Investors in Diodes (NASDAQ:DIOD) have unfortunately lost 41% over the last three years

Diodes Incorporated (NASDAQ:DIOD) shareholders should be happy to see the share price up 16% in the last month. But that doesn't help the fact that the three year return is less impressive. In fact, the share price is down 41% in the last three years, falling well short of the market return.

Since shareholders are down over the longer term, lets look at the underlying fundamentals over the that time and see if they've been consistent with returns.

While markets are a powerful pricing mechanism, share prices reflect investor sentiment, not just underlying business performance. 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.

Diodes saw its EPS decline at a compound rate of 32% per year, over the last three years. In comparison the 16% compound annual share price decline isn't as bad as the EPS drop-off. So, despite the prior disappointment, shareholders must have some confidence the situation will improve, longer term. This positive sentiment is also reflected in the generous P/E ratio of 47.47.

Investors in Diodes had a tough year, with a total loss of 20%, against a market gain of about 26%. 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. On the bright side, long term shareholders have made money, with a gain of 3% per year over half a decade. If the fundamental data continues to indicate long term sustainable growth, the current sell-off could be an opportunity worth considering. It's always interesting to track share price performance over the longer term. But to understand Diodes better, we need to consider many other factors.
