back to indexBogleheads University 501 2023 - The Case Against Factor Investing with Rick Ferri
00:00:00.000 |
And Rick had 35 years as a financial advisor. 00:00:11.200 |
He is a recognized champion for low investment fees. 00:00:14.520 |
I view him as the Jack Bogle heir apparent in a lot of ways. 00:00:19.440 |
But he's a pioneer in low-fee investment advice and portfolio management. 00:00:25.640 |
hundreds of articles, been published all over the place. 00:00:29.080 |
He's got a Master of Science in Finance from Walsh College. 00:00:32.920 |
He's also a CFA charter holder and he's a marine. 00:00:36.960 |
There's no such thing as a retired marine or an ex-marine. 00:00:39.600 |
He's a marine. He flew jets for the Marines for 21 years. 00:00:42.560 |
>> Thank you. Me, the case against factor investing. 00:00:53.400 |
And I told Paul, I don't really need 20 minutes, probably five. 00:01:04.680 |
Now, I'm going to describe what I put up here next. 00:01:10.040 |
So the bullet points will come up and then I'm going to talk about them. 00:01:13.840 |
So you don't really have to look at them on the screen. 00:01:22.400 |
this is just some basic stuff about the markets and the stock market. 00:01:27.240 |
Market beta, the return of the entire market, 00:01:33.720 |
explains most of the return of every diversified portfolio. 00:01:39.840 |
There've been several studies on this, several famous studies. 00:01:42.400 |
Eighty percent of the return of your diversified portfolio of stock. 00:01:50.120 |
the academics that did this, 100 stocks in each portfolio. 00:02:02.400 |
80 percent of the return or the variability of 00:02:06.200 |
any of those portfolios was based on the return of the market. 00:02:13.840 |
large growth, whatever you put in your portfolio, 00:02:19.840 |
is going to drive more actually than 80 percent of your stock return. 00:02:38.880 |
And Gene Fama, Nobel Prize Laureate Gene Fama, 00:02:49.120 |
And what that meant is that in addition to the 80 percent 00:02:58.720 |
about 20 percent or less will be explained by these other factors. 00:03:03.760 |
And that is the amount of stock in that portfolio 00:03:11.760 |
the amount in that portfolio which has more value stocks relative to the market, 00:03:16.840 |
the amount in that portfolio that has more quality stocks, 00:03:19.240 |
price momentum stocks relative to the market, 00:03:24.600 |
of the return of the variability of those portfolios. 00:03:33.800 |
I mean, there's a lot of marketing terms for this. 00:03:38.400 |
So in the end, what is going to drive your portfolio return is beta. 00:03:44.280 |
Beta is driving your return, and factor investing is sort of, 00:03:49.880 |
I don't know, the color of the flavor of the sprinkles 00:03:56.560 |
Now, most of the weight to additional factors, 00:04:00.320 |
this will determine what's called the tracking error, 00:04:03.000 |
the tracking error of your portfolio to the market. 00:04:05.520 |
So if you have more value stocks, you have more quality stocks, 00:04:09.840 |
you have more of these factors in your portfolio, 00:04:12.600 |
the return will track the return of the market, 00:04:15.040 |
but it might be more, which is the premium that Paul is hoping for, 00:04:19.880 |
or it could be less, and that's a negative tracking error, 00:04:23.160 |
which was what we've seen for the past almost 20 years, 00:04:30.240 |
so what I'm doing here is I'm going over some semantics. 00:04:32.600 |
The factor-tilted portfolio means you are starting 00:04:40.360 |
I know all the poor old slides were talking about the S&P 500 00:04:45.720 |
That's great for the presentation that he made, 00:04:49.760 |
I start with the Vanguard total stock market index fund, 00:04:52.760 |
which has small value in it, and it has everything else. 00:04:57.160 |
So you're going to get a factor-tilted portfolio. 00:05:02.800 |
and then you decide how much load you want to add to it, 00:05:15.760 |
and then that will determine your tracking error 00:05:18.720 |
to the market over the long term, that other 18%. 00:05:23.000 |
So now, the presumption with Paul's slides that go all the 00:05:35.680 |
I'm not going to argue with math that Paul put up there 00:05:47.040 |
it took large cap value minus small cap value. 00:05:52.040 |
In other words, it's a long-short strategy, long-short. 00:05:58.000 |
So you're going to go long, say, large cap growth stocks 00:06:06.160 |
to find out what the premium is on small cap growth. 00:06:31.360 |
But anyway, I don't want to get into the math of it too much. 00:06:32.880 |
The bottom line is, if you invest in these factors 00:06:37.080 |
and that premium is not positive, it's less than zero, 00:06:42.080 |
then you're going to have negative tracking error 00:06:51.560 |
It will, which is what we've seen for a long time. 00:06:58.800 |
using a tilted strategy is to be in it long enough, 00:07:10.080 |
You have to be committed to a factor-tilted portfolio 00:07:14.120 |
for probably 25 years to have a fairly high probability 00:07:19.120 |
that you will actually get the factor premiums. 00:07:33.560 |
okay, it's not gonna make that much difference, 00:07:39.800 |
You gotta get over that, what's called the hurdle rate, 00:07:42.200 |
and the hurdle rate, by the time you have to, 00:07:53.720 |
By the way, small cap value, everything else, 00:08:04.520 |
that Vanguard has to the total stock market index, 00:08:11.880 |
that I'll be talking about tomorrow with Jerry O'Reilly, 00:08:23.120 |
the return of the total stock market, even net of fees. 00:08:37.020 |
You can get a small cap value fund relatively cheap. 00:08:42.840 |
to small cap value, 'cause the cheaper you get, 00:08:45.840 |
it seems like the less the loadings to the value are. 00:08:48.560 |
In other words, loadings are how much of that fund 00:09:01.280 |
small cap value fund, it tends to be lower fee, 00:09:03.900 |
but it's also not high loadings to value factors. 00:09:07.900 |
I know we're talking, but this is the advanced group, right? 00:09:18.320 |
I want to look at these small cap value funds 00:09:30.760 |
to get the exposures to small cap and small cap value? 00:09:37.720 |
It's probably better if you're actually gonna do that, 00:09:41.280 |
because you'll find that when you look at the fees, 00:09:43.960 |
they're not that much higher than the less potent, 00:09:53.400 |
So I'm just saying that if I was gonna do small cap value, 00:09:55.400 |
I would buy the most potent small cap value fund 00:10:03.640 |
25 basis points, 30, 35, a lot higher than the total market. 00:10:09.980 |
You have to make that up before you're gonna outperform, 00:10:21.320 |
All right, this seems to be a real interesting thing, 00:10:24.280 |
phenomenon that happens in the academic world. 00:10:26.240 |
It's that when academics come out with a new study, 00:10:37.900 |
small cap stocks outperformed large cap stocks. 00:10:44.800 |
small cap mutual funds started to become very, very popular. 00:10:50.840 |
Since 1980, no more premium, no more premium. 00:11:01.720 |
Like Paul said, there's different value indexes. 00:11:04.440 |
That's true, value is in the eyes of the holder. 00:11:10.320 |
return on equity, enterprise value, on and on and on, 00:11:18.640 |
How have value stocks done relative to growth stocks 00:11:28.640 |
in basically the early 1990s, the Palmer French study? 00:11:50.520 |
and they said, if you were doing this back in the day, 00:11:53.820 |
you would have achieved higher rates of return. 00:12:05.320 |
And, but I mean, he's a really a fine researcher himself 00:12:12.520 |
Your Complete Guide to Factor-Based Investing. 00:12:17.460 |
And Larry has a library of over 3,000 different articles 00:12:25.380 |
on factor investing, the so-called Factors Zoo. 00:12:34.840 |
In his book, he cites 106 of these different factors. 00:12:58.440 |
They're very good at going back and looking at past data. 00:13:26.340 |
Of course, cameras weren't invented until the early 1800s. 00:13:33.440 |
But I bet if there actually were photographers 00:13:46.840 |
So in other words, same thing with back testing. 00:14:10.120 |
These institutional managers have to perform. 00:14:13.300 |
If they knew that value was gonna outperform growth, 00:14:18.400 |
What would that have actually done to the real world data? 00:14:23.220 |
We in a period now where since all this academic information 00:14:26.920 |
is now out there, that maybe the world has changed. 00:14:31.280 |
Maybe we're not gonna see these premiums going forward. 00:14:48.760 |
So factor tilts create what I call a behavioral risk. 00:15:21.980 |
From 2000 to 2007, after the tech stock bubble exploded, 00:15:32.960 |
I think, ever, and Paul, you can correct me on this. 00:15:36.040 |
I was in the money management business at the time. 00:15:47.680 |
Will you put me in a portfolio with DFA funds? 00:15:56.640 |
small cap value investment management firm at the time, 00:16:02.040 |
And the only way you could get access to DFA funds 00:16:07.000 |
and most of the advisors were charging 1% or more 00:16:23.280 |
"that's a little cheaper than DFA," whatever it was. 00:16:30.600 |
But you'll probably hear this tomorrow from Charlie Ellis. 00:16:39.440 |
Well, we had a long period of underperformance. 00:16:43.320 |
Since 2007, small cap value and factors in general 00:16:47.200 |
have underperformed the market significantly. 00:16:53.020 |
So what is that, 16 years, 17 years, roughly? 00:17:30.840 |
The last thing I want is complexity in my portfolio 00:17:36.400 |
So anyway, so the performance-chasing mentality 00:17:42.320 |
that got people into factor investing to begin with 00:17:48.040 |
They talk about the premiums that they delivered 00:17:53.200 |
but they don't talk about the mental aspect of it. 00:18:00.360 |
where people who got in during that I-gotta-have-DFA period 00:18:04.780 |
have already thrown in their hand, and guess what? 00:18:11.960 |
the stock market since inception, guaranteed, 00:18:14.620 |
because they have no chance of making that back 00:18:18.440 |
Therefore, I'm gonna tell you something John Bogle said. 00:18:22.320 |
John Bogle was way advanced, way advanced on this stuff. 00:18:31.320 |
over your retirement to just hold the stock market, 00:18:43.360 |
you own an index fund that owns the whole market, 00:18:54.580 |
You could be rewarded for adding additional factors 00:19:19.200 |
You're also making your portfolio more complex, 00:19:27.500 |
if it goes on for a long enough period of time, 00:19:31.240 |
and now you've permanently locked in on the performance 00:19:42.080 |
to the people who are already doing this, Paul. 00:19:51.160 |
I mean, you've been in it, you've been losing, 00:19:58.600 |
so you really need to stay in this thing, okay? 00:20:01.760 |
If you're thinking about adding additional factors, 00:20:09.600 |
and then you do a very heavily concentrated portfolio 00:20:15.980 |
And you need to do it for a very long period of time, 00:20:34.900 |
So remember, the most important decision we make, 00:20:38.460 |
the most important decision we make as investors 00:20:45.000 |
How much stock market beta are you going to have? 00:20:48.680 |
How much bond market beta are you going to have? 00:20:52.280 |
Jim Dolly gave the presentation about real estate, 00:21:05.920 |
small cap value investing, it's not important. 00:21:13.800 |
So this is something that it's hard to talk the talk 00:21:32.400 |
It's hard to swallow 17 years of underperformance. 00:21:39.840 |
What is the biggest risk of factor investing? 00:21:41.640 |
I don't think it's the fact that these premiums 00:21:46.360 |
I mean, I think that if enough people blow out 00:21:52.800 |
just keep on getting bigger and bigger and bigger 00:21:56.840 |
hey, hey, look at this, look at that, look at the spread. 00:22:00.840 |
We have except for next year, it gets cheaper.
