about an important concept that he calls the center lane. 00:00:31.960 |
Now we'll be doing the same thing with questions. 00:00:43.360 |
and you can step out there and ask question afterward 00:00:48.640 |
- Great, thank you, Jim, for that kind introduction. 00:00:56.280 |
except that one difference is that I don't disagree 00:01:07.840 |
but maybe a little bit of a different perspective. 00:01:10.680 |
So the title of the session is the center lane. 00:01:16.160 |
When I first started in the industry on the first day, 00:01:21.920 |
and he talked to me about how the firm worked 00:01:32.400 |
irrevocable trust, nuts and bolts, things like that. 00:01:36.500 |
But instead, the first thing that he talked about 00:01:42.200 |
I thought, I've spent all this time in school, 00:01:45.800 |
and the first thing that he wants to teach me 00:01:47.800 |
as a new person is about recency bias, behavioral concept. 00:01:55.280 |
I think probably everyone in this room appreciates 00:01:57.280 |
that there are two answers to every financial question. 00:02:04.720 |
But threading the needle is not always so easy. 00:02:12.040 |
where we have some data, but not complete data. 00:02:15.960 |
And so how do you make a decision in situations like that? 00:02:26.180 |
So one year I was on vacation with my family, 00:02:40.520 |
And I knew which exit it was, and I saw it coming up, 00:02:47.720 |
the kind of the yellow part, if you can make it out, 00:02:54.600 |
Needless to say, faced recriminations from my family 00:02:58.600 |
for spending, I don't know how much more time 00:03:00.600 |
than the sort of sweltering heat and the traffic in Miami. 00:03:04.860 |
But as I was sitting there hearing those recriminations, 00:03:11.680 |
then that actually would have been the better approach, 00:03:26.120 |
about this idea of the center lane, of hedging your bets. 00:03:36.100 |
I mean, oh, let me hedge my bets, split the difference. 00:03:42.360 |
That doesn't seem like the right way to approach things. 00:03:46.580 |
But as I thought more about it over the years, 00:03:54.200 |
So, you know, what is the importance of the center lane? 00:04:03.120 |
isn't the optimal answer the better way, right? 00:04:06.400 |
You know, shouldn't I at least try to optimize 00:04:09.300 |
rather than just, you know, splitting the difference 00:04:15.800 |
So let's look at the importance of the center lane. 00:04:27.120 |
His name is Ronald Wayne, and he was a co-founder of Apple 00:04:36.080 |
we don't talk about him a lot, he's still alive, 00:04:43.360 |
The reasons are a little bit lost to history. 00:04:53.660 |
And so he sold out, and you can look this up on Wikipedia, 00:05:03.200 |
Today, Apple, as you know, worth more than three trillion. 00:05:09.240 |
well, that's probably one of the biggest financial mistakes 00:05:16.360 |
well, gosh, that's with the benefit of hindsight. 00:05:19.120 |
And Wayne himself, in an interview, once said, 00:05:22.320 |
nobody could have anticipated how big Apple would become. 00:05:27.720 |
But I would like to argue that even Ronald Wayne, 00:05:31.720 |
with the information that he had available to him 00:05:34.440 |
at the time when they were just getting started, 00:05:40.600 |
If Steve Jobs made him nervous, he could have said, 00:05:42.400 |
well, I'm gonna go down at 5%, or I'll go down to 1%, 00:05:45.960 |
or I need to change the working relationship here, 00:05:55.800 |
but not have to deal with whatever the dynamics were 00:05:59.880 |
And so that's what I mean by the center lane. 00:06:04.600 |
but these kinds of things happen all the time. 00:06:13.500 |
there's that area which is just sort of trees and wilderness. 00:06:19.680 |
It's a very nice 35-acre parcel in Fort Lauderdale. 00:06:24.680 |
And it used to be the winter home of the Bartlett family. 00:06:28.640 |
A woman named Evelyn Bartlett lived there with her husband 00:06:38.080 |
and the property obviously had ballooned in value, 00:06:41.480 |
and she had a hard time keeping up with the real estate taxes. 00:07:11.020 |
Mrs. Bartlett went on to live until the age of 109. 00:07:20.160 |
because the property was so valuable, it was enormous, 00:07:23.400 |
she avoided tens of millions of dollars in property taxes. 00:07:26.880 |
And so Mrs. Bartlett got the better end of the deal. 00:07:34.600 |
Could this city have done something different? 00:07:37.640 |
What her proposal was, I don't want to pay any taxes at all, 00:07:54.360 |
In other words, it didn't need to be a binary choice. 00:07:59.200 |
So as I said, these examples occur all the time. 00:08:26.320 |
into a startup that another guy in their dorm 00:08:38.400 |
and that's, he said, this is the dumbest idea in the world. 00:08:48.720 |
And so Danny and I have talked about this over the years. 00:08:52.360 |
And as an economist, he's pretty thoughtful about it. 00:08:55.360 |
And sure, we have the same problem as with Ronald Wayne. 00:09:04.800 |
that he could have made a different decision. 00:09:07.680 |
I don't know how much savings he had as a college sophomore, 00:09:09.880 |
but he could have said, well, this seems dumb to me, 00:09:13.840 |
but I don't know, other people might like it, 00:09:18.720 |
So again, doesn't need to be a binary decision. 00:09:30.400 |
If you were Ronald Wayne or the city of Fort Lauderdale 00:09:33.560 |
or my friend Danny, what could you have done? 00:09:40.280 |
So I keep referring to splitting the difference. 00:09:45.640 |
And so I think there's a distinction to be made 00:10:05.360 |
In my house with all boys, it's not always fair 00:10:09.480 |
but that's the sort of situation where you'd say, 00:10:16.920 |
and I think this applies to a lot of financial decisions 00:10:20.080 |
where you could say, well, it shouldn't just be 50/50. 00:10:32.480 |
It might be, say you're considering a Roth conversion 00:10:48.040 |
And so in that case, you might just split the difference. 00:11:00.200 |
I'm not sure if you're familiar with Cass Sunstein. 00:11:07.440 |
including Danny Kahneman in behavioral finance. 00:11:10.560 |
And so in this book, he offers one suggestion. 00:11:14.960 |
He talks about when you're trying to weigh a decision, 00:11:23.080 |
The cost of being wrong against the benefit of being right. 00:11:26.760 |
And those are both easier to kind of get your arms around 00:11:31.120 |
than just simply trying to predict the future 00:11:37.880 |
if you think back to whether it was Ronald Wayne 00:11:42.120 |
you could say, well, let me try to put some numbers on this. 00:11:49.080 |
okay, well, I see the computer error is starting. 00:12:06.120 |
That wouldn't have been an unreasonable guess. 00:12:08.840 |
And then he could have done the math and said, 00:12:12.520 |
And it probably would have come out to way more 00:12:17.840 |
So that's one approach that you can take is to just say, 00:12:23.640 |
A similar example, when it comes to Facebook, 00:12:26.800 |
I remember talking to a pretty well-known venture capitalist 00:12:29.920 |
was in 2005, so just a year after they got started. 00:12:39.200 |
yeah, based on other types of deals and IPOs, 00:12:42.040 |
he said, I think the company would be worth 300 million. 00:12:45.160 |
And if I'm doing my math right, I think he was way off. 00:12:50.800 |
So Facebook's now worth more than 1 trillion. 00:13:03.080 |
And so I think that this is an important idea, 00:13:06.320 |
which is just to say, well, what's the cost of being wrong 00:13:15.200 |
especially as the previous speakers were talking about, 00:13:19.880 |
you're not talking about putting your entire net worth 00:13:36.680 |
And not just to dismiss it, like Danny and say, 00:13:48.000 |
if you're thinking about a financial decision, 00:13:50.300 |
is to say, well, how much do I need this to work? 00:13:56.160 |
what we were looking at is to think about the upside. 00:13:59.600 |
Now we wanna also think about the downside, right? 00:14:07.440 |
this person here really needs this bridge to hold. 00:14:15.160 |
Suppose you're trying to make an asset allocation decision. 00:14:18.320 |
And just as an illustration, let's imagine two people. 00:14:22.800 |
One is Bill Gates and one is more like an average person. 00:14:30.960 |
or he could have it all under his mattress, right? 00:14:41.340 |
But if you look at the sort of more average person, 00:14:44.660 |
suppose it's somebody who doesn't have a lot of savings 00:14:50.480 |
and they're looking to put a down payment on a home. 00:14:55.640 |
that probably should remain entirely in cash. 00:15:07.160 |
And if they need to put the down payment down anytime soon, 00:15:19.440 |
Okay, that's the theory, but how do we apply this? 00:15:37.120 |
And he compared asset allocation to making a fruit salad. 00:15:40.560 |
And if you haven't read this, it's a classic. 00:15:49.120 |
And it's a great way of describing diversification. 00:15:52.400 |
And I think that people really beat each other up 00:16:04.440 |
Some people say, well, have the market weight 00:16:15.680 |
And I think that people, they beat each other up about this 00:16:25.040 |
just think about what would be the cost of being wrong? 00:16:38.120 |
And in recent years, I don't know how many times 00:16:40.240 |
people have said, why don't I just put it all 00:16:44.360 |
Why am I messing around with any of this other stuff? 00:16:48.760 |
that's the easy button, just put all on the S&P 500. 00:16:51.440 |
And so I think it is, I would echo what Christine had said 00:16:59.760 |
that it is the hardest thing to convince people 00:17:05.680 |
which has just been practically a perennial loser, 00:17:10.320 |
But my view and sort of the center lane approach 00:17:14.160 |
would be to say, well, don't go too far out on a limb 00:17:19.560 |
And I think the recency bias is a good caution 00:17:30.160 |
Well, things can change and it's better to remain balanced. 00:17:38.080 |
comes from Morgan Housel, he described an old coach 00:17:41.440 |
and he said, 1/3 of your days should feel good, 00:17:44.160 |
1/3 should feel okay and 1/3 should feel terrible. 00:17:48.000 |
He says, if it's always terrible, you're doing it wrong, 00:17:49.720 |
if it's always great, then also you're not doing it right. 00:17:53.400 |
And I think that's also another important perspective 00:17:58.640 |
Which is that there's the expression that certainly 00:18:07.000 |
means that you're always apologizing for something. 00:18:12.120 |
but I think whether you're working with an advisor 00:18:16.400 |
and just maybe apologizing to your own spouse or to yourself 00:18:20.920 |
the idea is just keep going with the diversification 00:18:24.420 |
because if you become too convinced in any one direction, 00:18:34.620 |
So how could you apply the center lane approach 00:18:42.160 |
So actually Christine asked about direct indexing. 00:18:47.160 |
And so this is something that has grown in popularity. 00:18:58.480 |
And so I think there are definitely costs and complexity 00:19:03.480 |
which were discussed, but there are also some benefits. 00:19:24.800 |
So there are reasons why direct indexing can matter 00:19:29.200 |
or it can be valuable, but we shouldn't view it 00:19:32.960 |
as something that we feel that we shouldn't do 00:19:41.840 |
but at the end of the day, it's not a religion. 00:19:48.240 |
well, we'll do something that's a little bit different 00:19:55.320 |
And so I think that's another way in which you can say, 00:20:03.560 |
This one of my favorite cartoons is a little hard to read, 00:20:10.620 |
and their perspective on the rest of the world. 00:20:13.100 |
And so you can see beyond the Hudson River to them, 00:20:16.840 |
it's sort of like, then the next thing is the Pacific Ocean 00:20:25.000 |
and Jonathan said this in the previous session also, 00:20:28.160 |
that the question of international diversification 00:20:44.120 |
always said that his own portfolio was 100% domestic. 00:20:47.680 |
He said, what do I need the rest of the world for? 00:20:57.400 |
in which it's important to take a balanced view 00:21:02.560 |
to not be home biased, but there are also reasons 00:21:14.680 |
And so again, there's no one right answer here. 00:21:30.160 |
This here is a poll that I did a little while back. 00:21:47.640 |
in which I don't disagree with anything anyone else said. 00:21:50.440 |
What Jonathan described and Christine also added to 00:21:54.320 |
is to say, well, don't just hold a total bond fund. 00:21:57.640 |
And you can see that three quarters of people said, 00:22:08.400 |
government versus corporate, there's different durations, 00:22:11.700 |
and they behave differently in 2022, we saw that. 00:22:15.480 |
You can also buy individual bonds versus bond funds. 00:22:25.880 |
No, I think that each plays a role in a portfolio. 00:22:40.220 |
this is another area where you don't have to have 00:22:59.240 |
who ended up with some Apple shares, some Amazon shares, 00:23:08.840 |
there are lots of other ways to split the difference. 00:23:26.740 |
And here, just a quick thought on portfolio construction. 00:23:46.240 |
is just to say, well, let's not go too far out 00:23:50.760 |
in any one direction and let's not be too sure. 00:24:02.280 |
I'll skip over this and come to a conclusion. 00:24:19.400 |
or maybe even, it just looks like the most terrible thing. 00:24:30.020 |
but probably what I should have done was to buy some, right? 00:24:36.680 |
which is that, what I've developed over the years 00:24:47.680 |
but you also feel like you might kick yourself later, 00:24:51.840 |
and maybe it actually does turn into something 00:24:57.200 |
Again, going back to the Cass Sunstein theory, right? 00:24:59.560 |
Is there a way that I can place a small bet here? 00:25:08.960 |
And so, I'm glad my wife isn't in the audience, 00:25:11.520 |
so I can admit that the first time I looked at Bitcoin, 00:25:16.320 |
And so now it's, I don't know if it's 50, 60,000 today. 00:25:20.320 |
So I wish I had followed the $1,000 rule myself at the time. 00:25:28.320 |
in which you can apply the concept of the center lane. 00:25:38.360 |
and I'm not sure if we'll have time for questions, 00:25:40.100 |
but I will be around and happy to speak with folks. 00:25:58.860 |
Good, nice work talking about Bitcoin there at the end. 00:26:01.520 |
That was the first question on my docket there. 00:26:04.600 |
But thank you so much for your preparation and for your time.
