We think intelligent long term investing is the way to go. But that doesn't mean long term investors can avoid big losses.

Furthermore, it's down 12% in about a quarter. That's not much fun for holders.

While the efficient markets hypothesis continues to be taught by some, it has been proven that markets are over-reactive dynamic systems, and investors are not always rational. One way to examine how market sentiment has changed over time is to look at the interaction between a company's share price and its earnings per share (EPS).

During the five years over which the share price declined, Bank of Marin Bancorp's earnings per share (EPS) dropped by 19% each year. This change in EPS is remarkably close to the 19% average annual decrease in the share price. This implies that the market has had a fairly steady view of the stock. So it's fair to say the share price has been responding to changes in EPS.

What About Dividends?

As well as measuring the share price return, investors should also consider the total shareholder return (TSR). The TSR incorporates the value of any spin-offs or discounted capital raisings, along with any dividends, based on the assumption that the dividends are reinvested. So for companies that pay a generous dividend, the TSR is often a lot higher than the share price return. We note that for Bank of Marin Bancorp the TSR over the last 5 years was -58%, which is better than the share price return mentioned above. The dividends paid by the company have thusly boosted the total shareholder return.

A Different Perspective

While the broader market gained around 23% in the last year, Bank of Marin Bancorp shareholders lost 19% (even including dividends). Even the share prices of good stocks drop sometimes, but we want to see improvements in the fundamental metrics of a business, before getting too interested. Unfortunately, last year's performance may indicate unresolved challenges, given that it was worse than the annualised loss of 10% over the last half decade. We realise that Baron Rothschild has said investors should "buy when there is blood on the streets", but we caution that investors should first be sure they are buying a high quality business. While it is well worth considering the different impacts that market conditions can have on the share price, there are other factors that are even more important.
