Since June 2016, the team presently managing the Fund has now overseen a cumulative total return of 100%, versus 96% for the Index. While we hope and expect that the lead we have opened will widen in coming years, we are pleased that the Fund has outperformed a remarkably ebullient and resilient stock market— particularly during a past year punctuated by extraordinary events and increasingly extraordinary equity valuations in many areas. Companies that have demonstrated either an ability to dependably outgrow a plodding global economy or an exposure to areas of excitement like cloud software and electrified transportation now trade for valuations we have not seen since the late-90s dot-com bubble. If ever there was a year that illustrated the humbling nature of our profession, this was it. Recognizing that for many of you we are not just “a” money manager but “the” money manager, we have always considered a wide range of outcomes when evaluating potential investments and have tried to construct portfolios capable of compounding value come rain or shine. We have also always assumed that the world’s population of black swans is far larger than textbooks and conventional wisdom would have you believe— and that trying to predict where they will reveal themselves is a fruitless endeavor.Yet we readily admit that we were completely blindsided— dumbfounded, frankly— by the events that have transpired over the past year. More importantly in many ways, if we had somehow seen them coming, we still wouldn’t have guessed the reactions they elicited from markets and many businesses. Answering questions about the future turns out to be a sobering challenge even if you own a crystal ball. Which is why we try to answer as few of these questions as possible— and why we try to confine ourselves to the easier ones rather than the harder ones. We have always thought of forecasting the near-term direction of the economy or the stock market as akin to trying to predict the next month’s weather. We feel the same way about handicapping the probability of “tail risks” like nuclear wars, terrorist incidents, solar flares and, yes, viral pandemics. By contrast, we do think that with enough research and thoughtful debate, it is sometimes possible— but by no means easy— to make useful predictions about the future performance of an individual business. The task gets a little more manageable if you focus on advantaged businesses, because they’re naturally easier to assess. And still more manageable if you focus on gifted business managers, because they’re more likely to navigate the potholes you’ll inevitably overlook. And still more manageable if you focus on businesses that can grow independently of economic circumstances, because then you can ignore the weather, so to speak, and enjoy the luxury of only having to worry about if you’re right and not when you’re right. It also helps to purchase your holdings at prices that incorporate a margin of safety, because then when you’re wrong, you’re less likely to be very wrong, and when you’re right, every so often you’ll be really right. Sadly, even when you seek out the easier questions, you’re still bound to answer a portion of them incorrectly, which is why we try to construct our portfolios with a prudent balance of concentration and diversification. Because it takes time to research a business carefully enough to maximize the odds of analyzing it correctly, we focus our efforts on a narrow group of holdings. But not so narrow that we raise the stakes associated with being wrong to unacceptable levels, since one of the very few things you can know with complete certainty as an investor is that the world is full of surprises. A curious flu in China can turn into a global pandemic, driving the stock market down 30% in a monthѧand then up 15% for the year, to all-time highsѧwith some businesses ultimately doubling, tripling and quadrupling in value during a year many would understandably describe as the worst in living memory. The twists and turns of fate can be staggeringly unpredictable, but as we wrote during the peak of the pandemic, fifty years of history have taught us
