Three Mistakes to Avoid as a
Long-Term Investor: Part II

October 2023
View of the city in the mountains

In this second piece of our three-part series, we cover mistake No. 2: attempting to time the market.

In part one of the series, we looked at how focusing on metrics like return on equity and return on invested capital are key to long-term investing.

Attempting to time the market

Successful market timing can boost short-term returns, but it is fraught with risks and challenges — boosting returns in this manner consistently is incredibly difficult, if not impossible. While some investors may get lucky, achieving ongoing success is a different matter. Research linked in our piece, Three Mistakes to Avoid as a Long-term Investor: Observations from 35 Years Managing Money, reveals the significant underperformance of investors who missed the 10 best trading days each decade versus those who adopted a buy-and-hold approach. 

Our approach

For us, investing is about identifying great companies with enduring competitive advantages with the goal of achieving consistent and favorable outcomes for our clients. Rather than rely on chance, we dedicate significant time to studying companies and emphasize meticulous research, rigorous analysis and strategic decision-making in our process.

We also hold our positions for extended periods. Over time, we believe quality reveals itself, and based on our experience strong companies tend to outperform the broader market. Holding for the long-term also highlights the powerful potential of compounding, which can be a critical component of wealth creation.

Finally, holding quality companies during periods of market volatility can create opportunities for us to buy undervalued stocks, which we believe will ultimately benefit our investors.

In part three of the series, we examine the third mistake: focusing on the stock, not the company.
