0:00:18.720 --> 0:00:21.400
<v Speaker 1>not just a commodity power hies driving commodity prices. It's

0:00:21.440 --> 0:00:24.360
<v Speaker 1>a manufacturing power hives and has been putting in manufacturers

<v Speaker 1>someone who with Paul Wilmot change quantitative finance. Emmanuel Derman

0:00:44.880 --> 0:00:46.800
<v Speaker 1>will join us in this hour. There's gonna be a

<v Speaker 1>those of you driving. If you're at your desk, children

0:00:53.000 --> 0:00:57.640
<v Speaker 1>must leave the office as we speak to Derman of Columbia.

0:00:57.720 --> 0:01:00.400
<v Speaker 1>We will do that here in a big David Wilson's

<v Speaker 1>can talk for an hour in currency. But always interesting

0:01:51.160 --> 0:01:53.960
<v Speaker 1>stuff in the equity markets. David Wilson's what do you

0:01:54.000 --> 0:01:56.880
<v Speaker 1>have morning, Tom? I mean we have energy prices U

0:01:57.240 --> 0:02:00.680
<v Speaker 1>up and lots of dollar dynamics right, and ergy stocks

0:02:00.720 --> 0:02:03.800
<v Speaker 1>going along with them. Exxon Mobiles up half a percent

0:02:03.800 --> 0:02:07.320
<v Speaker 1>in early trading, Chevron and Conical Phillips with one percent

0:02:07.480 --> 0:02:11.280
<v Speaker 1>gained so far, Valiant Pharmaceuticals up four percent. The drug

0:02:11.320 --> 0:02:14.280
<v Speaker 1>maker asked lenders for an extension to file last year's

0:02:14.320 --> 0:02:18.519
<v Speaker 1>results until May thirty one. Now Valiant went into technical

0:02:18.560 --> 0:02:21.520
<v Speaker 1>default on some loans last month after failing to file

0:02:21.560 --> 0:02:24.640
<v Speaker 1>by March fifteen, and more defaults may follow if the

0:02:24.680 --> 0:02:27.799
<v Speaker 1>company doesn't deliver by April twenty nine, so that they're

0:02:27.800 --> 0:02:31.320
<v Speaker 1>looking to get out from under uh that pressure. Lulu

0:02:31.520 --> 0:02:33.960
<v Speaker 1>m Athletic of six percent. The yoga ware maker and

0:02:34.000 --> 0:02:36.760
<v Speaker 1>retailer posted fiscal fourth quarter earnings to beat the average,

0:02:36.760 --> 0:02:40.280
<v Speaker 1>anlessestment in the Bloomberg survey. Lulu Lemon benefited from cost

0:02:40.320 --> 0:02:44.360
<v Speaker 1>cuts and new products. Op Co Health, though down nine percent.

0:02:44.760 --> 0:02:48.320
<v Speaker 1>The drug maker said another company that manufactured its proposed

0:02:48.360 --> 0:02:52.680
<v Speaker 1>kidney treatment, Royaldi, was cited for deficiencies. Op Co has

0:02:52.680 --> 0:02:55.519
<v Speaker 1>filed for US approval of Royalty and said the production

0:02:55.560 --> 0:03:00.520
<v Speaker 1>issues don't directly affect that drug. Now Variant System down

0:03:00.680 --> 0:03:04.560
<v Speaker 1>fourteen percent. The data analysis software maker report of fiscal

0:03:04.560 --> 0:03:07.160
<v Speaker 1>fourth quarter property and revenue that were far below estimates.

0:03:07.320 --> 0:03:10.520
<v Speaker 1>Various forecast for this year showed it expects little or

0:03:10.600 --> 0:03:13.680
<v Speaker 1>no growth in its top and bottom lines. Land Star

0:03:13.800 --> 0:03:16.560
<v Speaker 1>System down five percent. The truck and company cut forecast

0:03:16.600 --> 0:03:20.000
<v Speaker 1>for first quarter earnings and sales to reflect falling revenue

0:03:20.080 --> 0:03:23.120
<v Speaker 1>per load. The drop amounts to about ten percent from

0:03:23.160 --> 0:03:27.320
<v Speaker 1>a year earlier. At Katia Pharmaceuticals up A US advisory

0:03:27.320 --> 0:03:30.840
<v Speaker 1>committee voted to support at katie is proposed treatment for

0:03:30.919 --> 0:03:35.640
<v Speaker 1>psychosis associated with Parkinson's disease. All Scripts Healthcare up four percent.

0:03:35.680 --> 0:03:38.080
<v Speaker 1>The medical software maker was raised. Equivalent can buy from

0:03:38.080 --> 0:03:41.560
<v Speaker 1>Hold Morgan Stanley Sonic up six and a half percent.

0:03:41.640 --> 0:03:44.280
<v Speaker 1>The drive in restaurant chains earnings and sales for the

0:03:44.520 --> 0:03:49.480
<v Speaker 1>fiscal second quarter receated projections UH Terraform power well, this

0:03:49.560 --> 0:03:52.080
<v Speaker 1>is it. This is the power plant owner created by

0:03:52.080 --> 0:03:54.200
<v Speaker 1>son Edison was cut. The equivalent of news from by

0:03:54.400 --> 0:03:59.000
<v Speaker 1>JP Morrigans and Shares sank fifty five percent yesterday after

0:03:59.000 --> 0:04:01.400
<v Speaker 1>its Terraform glow bull units start up filing that as

0:04:01.440 --> 0:04:04.520
<v Speaker 1>Parents faces substantial risk of bankruptcy. And I'll point out

0:04:04.560 --> 0:04:08.760
<v Speaker 1>Terraform Global down six Doing a value is what we call.

0:04:09.000 --> 0:04:11.920
<v Speaker 1>David Wilson, thank you so much, okay, folks, this is

0:04:11.920 --> 0:04:15.520
<v Speaker 1>a real pleasure. UM I will be direct. Paul Wilmot

0:04:15.640 --> 0:04:20.120
<v Speaker 1>changed the accessibility of quantitative finance, along with a lot

0:04:20.200 --> 0:04:23.479
<v Speaker 1>of other people. Bruno Dapierre, who were honored to say

0:04:23.480 --> 0:04:27.080
<v Speaker 1>works at Bloomberg LP. A guy named Taleb i'd throw

0:04:27.120 --> 0:04:30.160
<v Speaker 1>in their kent Osben who had a classic book. And

0:04:30.240 --> 0:04:34.520
<v Speaker 1>our next guest, Professor Dermot, Immanuel Dermot, Columbia University. Here's

0:04:34.520 --> 0:04:37.080
<v Speaker 1>what you need to remember. I will remember that I

0:04:37.120 --> 0:04:39.640
<v Speaker 1>didn't make the world, and it doesn't and it doesn't

0:04:39.680 --> 0:04:43.560
<v Speaker 1>satisfy my equations. Though I will use models boldly to

0:04:43.760 --> 0:04:48.640
<v Speaker 1>estimate value, I will not be overly impressed by mathematics.

0:04:48.880 --> 0:04:52.640
<v Speaker 1>And with that we welcome Emmanuel Dermant, professor. Wonderful to

0:04:52.720 --> 0:04:55.320
<v Speaker 1>have you on good morning, Good morning. I'm very glad

0:04:55.360 --> 0:04:59.080
<v Speaker 1>to be a I I look at Modelers of all Markets.

0:04:59.120 --> 0:05:01.600
<v Speaker 1>It's a classic. He's on the linkage of physics in

0:05:01.680 --> 0:05:05.560
<v Speaker 1>the finance. With great respect, I say, what did you

0:05:05.680 --> 0:05:10.359
<v Speaker 1>learn out of the crisis? The amplitudes that were mis

0:05:10.400 --> 0:05:13.919
<v Speaker 1>guests that you that you use every day, Now, what's

0:05:13.960 --> 0:05:18.919
<v Speaker 1>the new new for you? Seven years on? That's so

0:05:19.080 --> 0:05:21.880
<v Speaker 1>little has been learned in a way. I mean there

0:05:21.960 --> 0:05:24.920
<v Speaker 1>was a mass of failure, both of them. I think

0:05:24.960 --> 0:05:30.880
<v Speaker 1>of government and the FED after the after the crisis. Um,

0:05:30.920 --> 0:05:33.640
<v Speaker 1>you know, the crisis for me was was characterized by

0:05:33.680 --> 0:05:36.040
<v Speaker 1>several things. First of all, that piece you were reading

0:05:36.040 --> 0:05:39.600
<v Speaker 1>that Paul Wilmont and I wrote was called the modelers

0:05:39.680 --> 0:05:42.080
<v Speaker 1>and the financial modelers manifest that we were trying to

0:05:42.120 --> 0:05:46.719
<v Speaker 1>explain to people that social sciences and financial markets are

0:05:46.760 --> 0:05:50.040
<v Speaker 1>involved with people and not like physics systems, even though

0:05:50.080 --> 0:05:53.600
<v Speaker 1>the mathematics is similar, and people have to remember that, um,

0:05:53.600 --> 0:05:56.400
<v Speaker 1>that other people don't satisfy equations, even though you may

0:05:56.440 --> 0:05:58.680
<v Speaker 1>try to use equations to model them. In the end,

0:05:58.760 --> 0:06:02.120
<v Speaker 1>that's not the way they work. So um, that was

0:06:02.160 --> 0:06:04.279
<v Speaker 1>a good lesson, one that I actually learned ten years

0:06:04.279 --> 0:06:06.760
<v Speaker 1>before that, and nothing Paul Wood learned before that too.

0:06:07.200 --> 0:06:10.080
<v Speaker 1>But for me, the crisis has been so disappointing because

0:06:10.160 --> 0:06:15.480
<v Speaker 1>I'm we're sort of back in the same situation within

0:06:15.560 --> 0:06:18.040
<v Speaker 1>this is debate, and I want to stay away folks

0:06:18.040 --> 0:06:21.960
<v Speaker 1>from the mathiness and cross moments and blinding physics debates.

0:06:23.160 --> 0:06:25.960
<v Speaker 1>Token geek No, well, no, that rid Holes, very rid

0:06:25.960 --> 0:06:28.200
<v Speaker 1>Holes is here so he can be the token geek.

0:06:28.360 --> 0:06:31.839
<v Speaker 1>Are we have? We moved on from the simplicity of

0:06:31.880 --> 0:06:35.839
<v Speaker 1>the Gaussian or Bell curve distribution. It has been the

0:06:35.960 --> 0:06:40.400
<v Speaker 1>convenient model, going back to Fisher Black, even back to

0:06:40.480 --> 0:06:45.160
<v Speaker 1>bas Uh to mental block. But we've been doing the

0:06:45.160 --> 0:06:49.000
<v Speaker 1>Bell curve for years and we moved beyond the certitude

0:06:49.600 --> 0:06:54.560
<v Speaker 1>of that distribution. Yes, I think we have um The

0:06:54.680 --> 0:06:58.760
<v Speaker 1>trouble is there's nothing that replaces it was. What was

0:06:58.880 --> 0:07:01.520
<v Speaker 1>nice about the belt of was that it's a very

0:07:01.560 --> 0:07:06.240
<v Speaker 1>beautiful description of near what people call neoclassical finance, and

0:07:06.240 --> 0:07:08.080
<v Speaker 1>it would be great if the world worked that way.

0:07:08.120 --> 0:07:10.640
<v Speaker 1>It would be a beautiful system. But the world doesn't

0:07:10.680 --> 0:07:14.080
<v Speaker 1>work that way, and we've I think everybody knows that

0:07:14.120 --> 0:07:16.400
<v Speaker 1>the world doesn't work that way, but never really knows

0:07:16.440 --> 0:07:19.840
<v Speaker 1>what to replace it with. Professor tell Him has some

0:07:20.000 --> 0:07:24.120
<v Speaker 1>arguments about using fat tail distributions, but I think the

0:07:24.160 --> 0:07:27.640
<v Speaker 1>truth is people don't satisfy such simple there's no simple

0:07:27.680 --> 0:07:30.000
<v Speaker 1>model to replace it. So people have a hard time

0:07:30.000 --> 0:07:34.040
<v Speaker 1>mathematically with that. So when we're looking at models that

0:07:34.080 --> 0:07:39.840
<v Speaker 1>either depict the economy or an investment portfolio or any

0:07:39.880 --> 0:07:44.480
<v Speaker 1>specific asset class, how important is it for us not

0:07:44.680 --> 0:07:52.080
<v Speaker 1>to start out with assumptions that ultimately end up being disproven. Yes,

0:07:52.160 --> 0:07:56.800
<v Speaker 1>it's incredibly important all of those assumptions. A lot of

0:07:56.800 --> 0:07:59.400
<v Speaker 1>the models that the models that people make work for

0:07:59.480 --> 0:08:01.920
<v Speaker 1>a short time in a short regime when the markets

0:08:01.960 --> 0:08:05.640
<v Speaker 1>in a certain state, but as soon as things change,

0:08:05.800 --> 0:08:09.480
<v Speaker 1>it's driven by people. Obviously, that's almost the toutology, and

0:08:09.520 --> 0:08:13.600
<v Speaker 1>then all bets are off and there isn't some I mean,

0:08:13.640 --> 0:08:16.520
<v Speaker 1>part of what we were saying that exerved you read

0:08:16.680 --> 0:08:20.480
<v Speaker 1>was that there isn't a mathematics that describes people accurately,

0:08:20.560 --> 0:08:22.520
<v Speaker 1>and so you can't take solace in that. You have

0:08:22.600 --> 0:08:25.480
<v Speaker 1>to keep thinking, you have to stay aware. It's a

0:08:25.560 --> 0:08:28.360
<v Speaker 1>sort of human wish to find a formula that will

0:08:28.400 --> 0:08:30.640
<v Speaker 1>explain the market or explain what it's going to do,

0:08:30.720 --> 0:08:33.880
<v Speaker 1>but there isn't one, is my belief. Well, we certainly

0:08:33.920 --> 0:08:37.920
<v Speaker 1>can do worse than thinking about just basic mean reversion

0:08:38.520 --> 0:08:42.200
<v Speaker 1>as a way to think about different asset classes and

0:08:42.280 --> 0:08:50.120
<v Speaker 1>whether stocks, for example, are expensive or or inexpensive. Yes,

0:08:50.320 --> 0:08:53.360
<v Speaker 1>that's that's um. I think I think the right way

0:08:53.400 --> 0:08:54.800
<v Speaker 1>I agree with you, and I think the right way

0:08:54.840 --> 0:08:58.679
<v Speaker 1>to behave is is to use a mix of qualitative

0:08:58.720 --> 0:09:03.000
<v Speaker 1>and quantitative, not to be sort of blindingly quantitative. But

0:09:03.160 --> 0:09:04.680
<v Speaker 1>I don't think there's any I don't think there are

0:09:04.679 --> 0:09:07.000
<v Speaker 1>any permanent rules you look at the risk parity people.

0:09:07.000 --> 0:09:08.920
<v Speaker 1>I don't know if you're if your readers or your

0:09:08.960 --> 0:09:11.520
<v Speaker 1>listeners are familiar with rosparity. But that worked for a

0:09:11.559 --> 0:09:16.040
<v Speaker 1>long time. But that's not a solution either. Things. The

0:09:16.160 --> 0:09:19.160
<v Speaker 1>rule has change all the time within this and kent

0:09:19.360 --> 0:09:22.520
<v Speaker 1>osbin Folks has a fabulous book called Iceberg Risk. It

0:09:22.559 --> 0:09:25.320
<v Speaker 1>opens with two statisticians out at the tip of the

0:09:30.440 --> 0:09:34.840
<v Speaker 1>Iceberg gets to cut to the chase. But Emmanuel Derman

0:09:35.160 --> 0:09:41.240
<v Speaker 1>the whole idea of binomial or conventional mathematics versus not

0:09:41.360 --> 0:09:43.320
<v Speaker 1>a chaos. I don't want to go to cast theory,

0:09:43.640 --> 0:09:47.080
<v Speaker 1>but a more disjoint mathematics. Which is right or do

0:09:47.120 --> 0:09:50.120
<v Speaker 1>we have to learn to use both? I think you

0:09:50.200 --> 0:09:52.520
<v Speaker 1>have to be I think you have to be disjoint.

0:09:52.559 --> 0:09:55.239

0:10:01.280 --> 0:10:03.560
<v Speaker 1>you have to do. It's good to think about as

0:10:03.559 --> 0:10:05.960
<v Speaker 1>many different models as you can that are consistent with

0:10:06.040 --> 0:10:09.199
<v Speaker 1>what you know, but have different futures, and be skeptical

0:10:09.200 --> 0:10:11.600
<v Speaker 1>of them all, but try to see which one works

0:10:11.720 --> 0:10:14.640
<v Speaker 1>best for now. So you know, prices over earnings models

0:10:14.840 --> 0:10:19.920
<v Speaker 1>or more complicated, you know, neoclassical binomial models. They all

0:10:19.960 --> 0:10:23.160
<v Speaker 1>have their fifteen minutes of fame, but they don't last forever.

<v Speaker 1>you to the conversation is Frequently Asked Questions in Quantitative

0:14:05.400 --> 0:14:08.680
<v Speaker 1>also happens to be a fun book as well. Emmanuel Dermott,

0:14:08.679 --> 0:14:11.000
<v Speaker 1>I want to talk about what we learned from failure

0:14:11.080 --> 0:14:15.000
<v Speaker 1>not seem to Leb wrote the brilliant Anti Fragile about

0:14:15.120 --> 0:14:19.160
<v Speaker 1>learning from our disorder, learning from when things break, how

0:14:19.240 --> 0:14:22.560
<v Speaker 1>to move on and do better. Explain to us from

0:14:22.600 --> 0:14:26.960
<v Speaker 1>the Emmanuel Derman world, how we get wiser from our

0:14:27.040 --> 0:14:34.120
<v Speaker 1>quantitative mistakes. You know how sort of take us off

0:14:34.160 --> 0:14:35.640
<v Speaker 1>to a point of view to it, and that is

0:14:35.720 --> 0:14:40.240
<v Speaker 1>that people are people are. Nutrition and finance are kind

0:14:40.280 --> 0:14:42.600
<v Speaker 1>of very simple and are very similar, and that people

0:14:42.640 --> 0:14:46.600
<v Speaker 1>are always looking for some little bit of data that

0:14:46.720 --> 0:14:49.120
<v Speaker 1>they can use to predict the future. So for yours,

0:14:49.320 --> 0:14:52.640
<v Speaker 1>if you look at nutrition, um, people thought you needed

0:14:52.680 --> 0:14:54.680
<v Speaker 1>a lower amount of vitamin D, and then I think

0:14:54.760 --> 0:14:57.600
<v Speaker 1>you need the U s D. A keeps changing the

0:14:58.240 --> 0:15:02.400
<v Speaker 1>bitimum recommended requirements or vitamins and for various kinds of food,

0:15:02.480 --> 0:15:05.360
<v Speaker 1>and ten years later they change everything. And that's because

0:15:05.400 --> 0:15:07.880
<v Speaker 1>people have the terrible need, which is understandable, to be

0:15:08.000 --> 0:15:10.760
<v Speaker 1>told what to do when there isn't always a clear answer.

0:15:10.880 --> 0:15:14.600
<v Speaker 1>And I think finance is very similar. People glom onto

0:15:14.800 --> 0:15:17.040
<v Speaker 1>some kind of quantitative model and they use it for

0:15:17.080 --> 0:15:19.640
<v Speaker 1>a while. You see this a lot in statistical arbitragety.

0:15:19.680 --> 0:15:21.440
<v Speaker 1>It may work for a while, but then it fails.

0:15:21.960 --> 0:15:24.800
<v Speaker 1>And I think the lesson is kind of a philosophical

0:15:24.880 --> 0:15:27.400
<v Speaker 1>one that you sort of shouldn't be an idolator. An

0:15:27.440 --> 0:15:29.440
<v Speaker 1>idolator in the sense that you think you can make

0:15:29.480 --> 0:15:33.480
<v Speaker 1>an image of society, of human the human mind with

0:15:33.680 --> 0:15:36.040
<v Speaker 1>a formula or a prescription, and that it's always going

0:15:36.080 --> 0:15:42.840
<v Speaker 1>to work. So given that constantly skeptical, constantly skeptical, constantly

0:15:42.880 --> 0:15:46.920
<v Speaker 1>trying out new models, but don't don't make the transision

0:15:46.960 --> 0:15:49.560
<v Speaker 1>into hubris where you think you found the permanent solution.

0:15:50.080 --> 0:15:53.520
<v Speaker 1>So so, given that, does that mean investors have to

0:15:53.800 --> 0:15:59.040
<v Speaker 1>constantly be rethinking their philosophy in light of how humans

0:15:59.200 --> 0:16:02.120
<v Speaker 1>behave and miss behave in the market or can we

0:16:02.280 --> 0:16:06.160
<v Speaker 1>come up with the belief system that recognizes both the

0:16:06.280 --> 0:16:10.120
<v Speaker 1>math half and the psychology half of what takes place

0:16:10.240 --> 0:16:14.800
<v Speaker 1>in capital markets? Yeah, I think that psychology is dominant

0:16:14.920 --> 0:16:17.600
<v Speaker 1>and the math is an attempt to describe the psychology

0:16:18.720 --> 0:16:23.200
<v Speaker 1>and to formalize it in mathematical terms. And there isn't

0:16:23.240 --> 0:16:26.120
<v Speaker 1>going to be a permanent answer because when when regimes

0:16:26.160 --> 0:16:29.720
<v Speaker 1>in the market change, things change. And um, I look

0:16:29.720 --> 0:16:33.080
<v Speaker 1>a lot of option pricing and the nature of options

0:16:33.200 --> 0:16:35.480
<v Speaker 1>on for example, on the S and P changed after

0:16:35.560 --> 0:16:37.880
<v Speaker 1>the seven crash, and it's never been the same sense.

0:16:37.920 --> 0:16:42.000
<v Speaker 1>I'm writing a book called the Volatility Smile excuse me,

0:16:42.080 --> 0:16:45.320
<v Speaker 1>which is all about that phenomenon. And then gold similar

0:16:45.400 --> 0:16:48.200
<v Speaker 1>the options on gold suddenly changed in the late nineties

0:16:48.240 --> 0:16:51.760
<v Speaker 1>when the Swiss Central Bank did something different. And so yeah,

0:16:51.800 --> 0:16:55.240
<v Speaker 1>you've got to constantly understand how people psychology is changing

0:16:55.280 --> 0:16:57.800
<v Speaker 1>and then use the relevant math for a while. The

0:16:57.920 --> 0:17:02.000
<v Speaker 1>relevant math has an anchor. It may be a philosophical

0:17:02.080 --> 0:17:04.760
<v Speaker 1>anchor which is too deep for our radio. We wouldn't

0:17:04.800 --> 0:17:06.760
<v Speaker 1>even do that on TV. I mean, that's something you do.

0:17:07.400 --> 0:17:10.680
<v Speaker 1>You know with that fancy bookstore by Columbia Universities around

0:17:10.720 --> 0:17:13.160
<v Speaker 1>having a cup of coffee. It is a great bookstore,

0:17:13.200 --> 0:17:15.639
<v Speaker 1>and I think it's a hundred and twelve street. Uh uh,

0:17:16.200 --> 0:17:20.760
<v Speaker 1>Professor Dermot. Everybody wants to know where Bill Sharp's risk

0:17:20.880 --> 0:17:25.359
<v Speaker 1>free rate is. Every sophisticated global Wall Street or listening worldwide.

0:17:25.840 --> 0:17:30.280
<v Speaker 1>Those less sophisticated, they foundationally know there's a thing called

0:17:30.320 --> 0:17:32.600
<v Speaker 1>the risk free rate? Do you know where it is

0:17:32.800 --> 0:17:35.520
<v Speaker 1>right now? Or have we so distorted the system We

0:17:35.600 --> 0:17:39.200
<v Speaker 1>don't have a clue where our anchor is a little

0:17:39.240 --> 0:17:41.159
<v Speaker 1>bit on the side of what you just said that

0:17:41.320 --> 0:17:45.439
<v Speaker 1>I'm as distorted the system totally. The risk free rate

0:17:45.560 --> 0:17:48.560
<v Speaker 1>is low because some people are very risk averse, but

0:17:49.080 --> 0:17:52.359
<v Speaker 1>it's being set by the Fed in some very artificial

0:17:52.440 --> 0:17:55.240
<v Speaker 1>way that we've all gotten used to. And um um,

0:17:56.000 --> 0:17:58.200
<v Speaker 1>I think nobody really knows is it negative? Is it

0:17:58.600 --> 0:18:02.080
<v Speaker 1>going to get more negative? It's become It's it's very

0:18:02.119 --> 0:18:04.440
<v Speaker 1>strange for me. I mean, interest rates on the price

0:18:04.560 --> 0:18:09.360
<v Speaker 1>of money, and we're always against manipulating, manipulating the price

0:18:09.440 --> 0:18:11.320
<v Speaker 1>of things, and yet we all live with the fit

0:18:11.400 --> 0:18:15.600
<v Speaker 1>manipulating the price of money. That is the standard background.

0:18:16.080 --> 0:18:19.760
<v Speaker 1>There's always going to be some force out there impacting

0:18:19.840 --> 0:18:22.760
<v Speaker 1>what takes place in the market. It's our job to

0:18:23.560 --> 0:18:27.240
<v Speaker 1>figure out how to navigate those waters, isn't it. Yes?

0:18:27.440 --> 0:18:29.879
<v Speaker 1>And these days, for the last five years, it's all

0:18:29.920 --> 0:18:33.359
<v Speaker 1>a risk on risk off situation where people either punge

0:18:33.440 --> 0:18:35.399
<v Speaker 1>in and think everything is going to be good because

0:18:35.480 --> 0:18:39.119
<v Speaker 1>the fit is in is doing something good, or um

0:18:39.560 --> 0:18:42.520
<v Speaker 1>risk off and everything's in trouble. Did you have a

0:18:42.640 --> 0:18:46.040
<v Speaker 1>cue full and as or slide rule? Excuse me? Did

0:18:46.080 --> 0:18:48.840
<v Speaker 1>you have a slide role when you were in school? Oh? Yes,

0:18:49.280 --> 0:18:51.640
<v Speaker 1>once treated a picture of one a few years ago. Yeah,

0:18:51.680 --> 0:18:54.200
<v Speaker 1>I've got this old fabric castell slide rule from the

0:18:54.320 --> 0:18:57.680
<v Speaker 1>seventies of the sixties. Am I right? In that we

0:18:57.760 --> 0:19:01.840
<v Speaker 1>sort of lost something without the physical feeling of logarithms

0:19:01.880 --> 0:19:04.800
<v Speaker 1>off a slide rule versus everybody today. All your kids

0:19:04.840 --> 0:19:08.360
<v Speaker 1>at school today are all wis bang. You know, that's

0:19:08.400 --> 0:19:10.240
<v Speaker 1>a that's a I never thought of that, but that's

0:19:10.280 --> 0:19:14.960
<v Speaker 1>a that's a great, great insight in that calculation used

0:19:15.000 --> 0:19:17.560
<v Speaker 1>to be a physical thing with the slide rule. Yeah, well,

0:19:17.600 --> 0:19:20.520
<v Speaker 1>you used to look up logarithmic tables before that. Exactly

0:19:20.560 --> 0:19:23.040
<v Speaker 1>high school, Yeah, exactly. I mean this has been wonderful.

0:19:23.080 --> 0:19:25.480
<v Speaker 1>Emmanuel Dermot. I hope we can do this again. He

0:19:25.640 --> 0:19:29.760
<v Speaker 1>is a Columbia University, which barely describes his contribution to

0:19:30.359 --> 0:19:34.119
<v Speaker 1>the underpinnings of finance. Things branted every day, ran the

0:19:34.280 --> 0:19:38.960
<v Speaker 1>infamous quantitative Strategies group at Dolman SATs yes, and had

0:19:39.359 --> 0:19:42.399
<v Speaker 1>a number of other um efforts, of course, out of

0:19:42.440 --> 0:19:45.359
<v Speaker 1>the University of Cape Town originally, and of course his

0:19:45.960 --> 0:19:50.119
<v Speaker 1>truly his Columbia University. It's a very Columbia university. It is.

0:19:50.240 --> 0:19:52.320
<v Speaker 1>Let me do a shameless plug for the masters in

0:19:52.400 --> 0:19:56.760
<v Speaker 1>business we did with him. It was phenomenal. Quantz still
