“Activity is the enemy of investment returns.” – Warren Buffett
We believe there are a couple of reasons why this statement is spot on for most investors. First, the primary input many people use is whether the security has performed well or poorly. Some investors are quick to take profits on securities that have gained even when the fundamental story is still intact (e.g., the security has appreciated in line with things like underlying growth in sales, earnings or cash flow per share). On the other side of the spectrum, many investors have a propensity to buy into market segments that have performed exceedingly well and parting with those that have ‘failed to keep up.’ Reversals are common. Securities that have been disappointing to own could prove to be the winners going forward. Others that have performed exceedingly well can fall precipitously if their valuation metrics compress – for a variety of reasons. As you know, our approach is not based upon buying or selling based upon price movement per se. Rather, we actively seek out securities that tend to perform differently over time. We also look to identify and patiently own segments that are inexpensive relative to their own history and other market segments. That’s because, when conditions improve and/or sentiment turns favorable, these securities can surprise on the upside.
“I view diversification not only as a survival strategy but as an aggressive strategy because the next windfall might come from a surprising place.” – Peter L. Bernstein
As steadfast proponents of diversification, we believe this statement is powerful. First, history shows that most market segments come into and out of favor. Indeed, pronounced leadership changes often occur when they are least expected. Therefore, investors are well served to purposefully own investment assets that have historically performed differently from one another over time. True diversification entails a willingness to go against the grain by actively seeking opportunities to invest in market segments that are out of favor with respect to most investors. Collectively, most investors shun investments that have performed poorly of late and where sentiment is palpably low. The key to avoiding ‘group think’ is using valuation metrics as a primary input and then exercising patience. For instance, at what proved to be the bottom of the GFC (great financial crisis) in 2009, most investors viewed things like the S&P 500 as inherently risky.i However, long-term oriented investors who use valuation as a primary input were more readily able to not only stay the course but to add to positions. Indeed, we think it is helpful to ask things like, ‘What is the likelihood that this segment will perform poorly over the next 5 years if the economy improves?’ The reverse is also true for dearly loved segments. Will they perform well if the economy is not robust in light of current high valuation metrics?
The table below shows how difficult it is for even well-known and resourced companies to stay at the top of the leaderboard.

One of the things that make it difficult for stocks to stay on top is the fact that valuation metrics can expand such that their share of an index’s value significantly exceeds their respective earnings contribution. As the chart below shows, the PE ratio for the largest 10 components of the S&P 500 is elevated compared to the remaining 490 stocks (all equal weighted). This was true during the dotcom bubble. The largest and most expensive stocks fared particularly poorly from their highs. Historically, the bottom 490 have performed relatively well when the top 10 lose significant valuation (see the table below).ii

Here are a few more of my favorite quotes from Mr. Bernstein –
- “What’s comfortable is not the right way to You must own things that you’re uncomfortable with. Otherwise, you’re not really diversified.”
- “Survival is the only road to ”
- “The constant lesson of history is the dominant role played by Just when we are most comfortable with an environment and come to believe we finally understand it, the ground shifts under our feet.”
