As every investor would know, not every swing hits the sweet spot. But really bad investments should be rare. So take a moment to sympathize with the long term shareholders of Zoom Video Communications, Inc. (NASDAQ:ZM), who have seen the share price tank a massive 85% over a three year period. That might cause some serious doubts about the merits of the initial decision to buy the stock, to put it mildly. We really hope anyone holding through that price crash has a diversified portfolio. Even when you lose money, you don't have to lose the lesson.

After losing 3.0% this past week, it's worth investigating the company's fundamentals to see what we can infer from past performance.

In his essay The Superinvestors of Graham-and-Doddsville Warren Buffett described how share prices do not always rationally reflect the value of a business. 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).

Zoom Video Communications saw its EPS decline at a compound rate of 3.7% per year, over the last three years. The share price decline of 47% is actually steeper than the EPS slippage. So it's likely that the EPS decline has disappointed the market, leaving investors hesitant to buy.

A Different Perspective

While the broader market gained around 18% in the last year, Zoom Video Communications shareholders lost 15%. 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 6% over the last half decade. Generally speaking long term share price weakness can be a bad sign, though contrarian investors might want to research the stock in hope of a turnaround. It's always interesting to track share price performance over the longer term. But to understand Zoom Video Communications better, we need to consider many other factors.
