It's not possible to invest over long periods without making some bad investments. But you want to avoid the really big losses like the plague. So consider, for a moment, the misfortune of Zoom Video Communications, Inc. (NASDAQ:ZM) investors who have held the stock for three years as it declined a whopping 82%. That would be a disturbing experience. Shareholders have had an even rougher run lately, with the share price down 13% in the last 90 days. While a drop like that is definitely a body blow, money isn't as important as health and happiness.

Since Zoom Video Communications has shed US$794m from its value in the past 7 days, let's see if the longer term decline has been driven by the business' economics.

To paraphrase Benjamin Graham: Over the short term the market is a voting machine, but over the long term it's a weighing machine. One imperfect but simple way to consider how the market perception of a company has shifted is to compare the change in the earnings per share (EPS) with the share price movement.

Zoom Video Communications saw its EPS decline at a compound rate of 4.3% per year, over the last three years. This reduction in EPS is slower than the 43% annual reduction in the share price. So it seems the market was too confident about the business, in the past.

A Different Perspective

Investors in Zoom Video Communications had a tough year, with a total loss of 8.8%, against a market gain of about 22%. However, keep in mind that even the best stocks will sometimes underperform the market over a twelve month period. Unfortunately, last year's performance may indicate unresolved challenges, given that it was worse than the annualised loss of 1.5% 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.
