And in 1996 Warren Buffett said, “Diversification is protection against ignorance. “
So you might think a very concentrated portfolio is the answer to wealth creation?
It is, if you can accurately predict the future
But you can’t
So I asked Perpexity, how many companies Peter Lynch held on average
“theĀ averageĀ number of holdings was around 200 stocks in the portfolio, and at its peak in 1989 it reportedly reached about 1,400 holdings”
I bet you weren’t expecting 200
So then I asked
“How has the total number of investments Berkshire Hathaway owned, changed over the years?”
“In the late 1970s and 1980s, Berkshireās investments were essentially a few dozen material positions overall
By the early 2020s, Berkshire had grown into a conglomerate with of the order of 60ā70 majorityāowned subsidiaries spanning insurance, railroads, energy, manufacturing, and retailing to well over 100 distinct business and stock investments today.”
so a few dozen to 100 across many industries
And how about UK investing legend, Anthony Bolton?
“Boltonās style across his major funds was to hold roughly 40ā100 stocks at a time”
My conclusion is that we know about these investing legends because of their great returns and because they survived in the markets over long periods of time, giving compounding time to work. Part of that “survival” is being diversified
I’m in good company because
In a 2019 a Morningstar paper studying the impact of portfolio concentration on returns, the author, Alex Bryan, CFA, concluded,
āThe idea that investing with conviction improves returns is a myth. Increasing portfolio concentration is just as likely to hurt returns as it is to help.ā
Over the past 12 months, some big holdings in some big funds have taken big hits:
– Novo Nordisk is down 54%,
– RELX is down 47%,
– LSEG is down 26%,
So maybe it’s time to reconsider the common notion that “high conviction investing” is the answer
In our January factsheet (comments), we make our case for a more diversified portfolio
Especially in a fast-changing world
