There’s an previous saying that goes, “Focus to get wealthy, diversify to remain wealthy.” The concept being that you need to put all your belongings into one (or a number of) funding(s) to construct your wealth after which unfold your capital round later in life to protect it.
Nevertheless, the longer I’ve been investing the extra I’ve come to despise this phrase. As a result of whereas focus can result in riches, it may well additionally result in smash. This is named focus danger and there are many examples of it all through monetary historical past:
The monetary graveyard of historical past is full of concentrated traders.
And simply final week, Silicon Valley Financial institution (SVB), the premier financial institution to Silicon Valley startups, turned the most recent sufferer to affix their ranks after a financial institution run pressured them into receivership with the FDIC.
The place did the sixteenth largest financial institution within the U.S. go unsuitable almost about focus danger? Let’s dig in.
How Focus Danger Killed Silicon Valley Financial institution
In the case of the demise of SVB, there are two areas the place focus danger performed a pivotal function.
First, SVB had a concentrated place in longer-term Treasury bonds which they acquired earlier than the latest rise in rates of interest. Due to this fact, as charges elevated all through 2022, their bond portfolio took an enormous hit. As Marc Rubinstein acknowledged in his excellent overview of SVB’s demise:
Unrealised losses snowballed, from nothing in June 2021, to $16 billion by September 2022…So massive was this drawdown that on a marked-to-market foundation, Silicon Valley Financial institution was technically bancrupt on the finish of September. Its $15.9 billion of HTM mark-to-market losses fully subsumed the $11.8 billion of tangible frequent fairness that supported the financial institution’s steadiness sheet.
However, what made the primary focus downside worse was a second focus downside—SVB’s buyer base.
In contrast to many different banks in america, SVB specialised in banking for startups. In truth, according to SVB’s own marketing, almost half of the 130,000 venture-backed startups within the U.S. banked with SVB.
In consequence, SVB was extra inclined to macroeconomic shocks that might negatively influence its homogenized buyer base. Sadly, the one macroeconomic shock that might hurt SVB’s clients was the identical shock that might hurt its belongings—rising rates of interest.
So when rising charges materialized, SVB went right into a dying spiral. As Matt Levine summarized:
And so for those who had been the Financial institution of Startups…it turned out that you simply had made an enormous concentrated wager on rates of interest. Your clients had been flush with money, in order that they gave you all that money, however they didn’t want loans so that you invested all that money in longer-dated fixed-income securities, which misplaced worth when charges went up.
But in addition, when charges went up, your clients all bought smoked, as a result of it turned out that they had been creatures of low rates of interest, and in a higher-interest-rate setting they didn’t have cash anymore. In order that they withdrew their deposits, so that you needed to promote these securities at a loss to pay them again. Now you might have misplaced cash and look financially shaky, so clients get spooked and withdraw more cash, so that you promote extra securities, so that you ebook extra losses, oops oops oops.
That is an instance of how focus can go unsuitable quick.
However to supply a extra sensible instance of how focus danger impacts a typical investor, we flip to our subsequent part.
Visualizing Focus Danger (for the Typical Investor)
If you need a visualization of focus danger, you solely want to check the efficiency of the Russell 3000 Index versus its particular person inventory elements for 2021 and 2022.
I’ve achieved this within the plot under which reveals the efficiency of the Russell 3000 Index (in purple) and every of its underlying shares (in grey) all through 2021 [Note: the y-axis is a log-scale]:
This plot demonstrates the dispersion in efficiency that accompanies extra concentrated positions (i.e. particular person shares). Particularly, some shares grew by 3x (or extra) whereas others had been minimize in half. The twenty fifth percentile efficiency was 0%, the median efficiency was +23%, and the seventy fifth percentile efficiency was +49% in 2021. This all occurred in a yr the place the Russell 3000 Index was up 26% (e.g. $1 grew to $1.26 by yr finish).
Nevertheless, 2021 was a great yr for many shares and inventory indices. If we had been to plot the identical factor for 2022 (a not so good yr), then the story can be fairly completely different:
Now we are able to see the downsides of concentrated positions a bit extra clearly. In 2022 there have been no shares that went up 10x or extra (like we noticed in 2021) and there have been even fairly a number of shares that misplaced over 70% of their cash by yr finish (e.g. $1 turned $0.30). Particularly, the twenty fifth percentile efficiency was -38%, the median efficiency was -18%, and the seventy fifth percentile efficiency was +3%. This was in a yr the place the Russell 3000 Index misplaced 20% (e.g. $1 turned $0.80) by December 2022.
Whereas these plots present empirical proof for the riskiness of concentrated positions, the theoretical proof exists as nicely. As Lazard highlighted in this review of studies discussing concentrated portfolios, because the variety of shares in your portfolio will increase, the usual deviation of your portfolio (i.e. danger) drops:
Particularly, going from a 1-stock portfolio to a 5-stock portfolio cuts the usual deviation in half, and going from a 5-stock portfolio to a 50-stock portfolio reduces the usual deviation by one other 40%.
This demonstrates how avoiding focus can cut back danger on the portfolio stage. Nevertheless, there are different issues we are able to do in our monetary lives to keep away from focus danger as nicely.
How you can Keep away from Focus Danger (and the Limits to Diversification)
After we discuss avoiding focus danger, we’re usually referring to the danger you are taking inside your portfolio. Nevertheless, there are various different areas of your monetary life the place lowering focus danger may very well be equally, if no more, impactful. For instance, you may:
- Increase your banking relationships. With all the pieces that occurred within the final week at SVB, now is an effective time to re-evaluate whether or not you need to have a secondary banking relationship in case your major financial institution will get into monetary hassle.
- Construct a number of streams of earnings. Counting on a single supply of earnings, reminiscent of a job or a enterprise, can depart you weak to surprising adjustments in employment or market circumstances. Contemplate creating multiple streams of income, reminiscent of rental properties, royalties, or different income-producing assets to mitigate this danger.
- Have completely different insurance coverage suppliers. Relying on a single insurance coverage supplier to cowl all of your wants might be dangerous, particularly if that supplier experiences monetary troubles or protection adjustments. Contemplate diversifying your insurance coverage insurance policies throughout a number of suppliers to make sure ample protection.
- Diversify your geographic location. Concentrating your monetary life in a single geographic location might be dangerous if that space experiences a pure catastrophe, financial downturn, or different unexpected occasion. Contemplate diversifying your belongings and investments throughout completely different areas and international locations to unfold out this danger. Although this will likely be straightforward for an index investor, somebody who owns bodily actual property/companies might discover this tougher.
Whereas I may proceed including to this checklist by together with the diversification of what currencies you maintain, your profession expertise, and so forth, the reality is that diversification has its limits. We will’t hedge all the pieces in life. In some unspecified time in the future we have now to take some precise danger.
In spite of everything, what would life be like with out danger? Might we construct something of substance? And would we even get pleasure from it?
I don’t suppose so. In truth, a number of the finest issues in life require danger and concentrated danger at that. For instance, selecting a accomplice, elevating a household, and mastering a ability are all issues the place diversification will lead you astray. These are areas the place immense dedication of time, vitality, and sources are required.
So whereas focus danger isn’t your good friend in your monetary life, I wouldn’t be so weary of it all over the place else. Completely happy investing and thanks for studying.
