If you love investing in stocks you're bound to buy some losers. But the last three years have been particularly tough on longer term Amtech Systems, Inc. (NASDAQ:ASYS) shareholders. Unfortunately, they have held through a 57% decline in the share price in that time. Even worse, it's down 11% in about a month, which isn't fun at all.
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 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.
Amtech Systems saw its share price decline over the three years in which its EPS also dropped, falling to a loss. This was, in part, due to extraordinary items impacting earnings. Since the company has fallen to a loss making position, it's hard to compare the change in EPS with the share price change. But it's safe to say we'd generally expect the share price to be lower as a result!

A Different Perspective
Amtech Systems shareholders gained a total return of 4.0% during the year. But that was short of the market average. If we look back over five years, the returns are even better, coming in at 6% per year for five years. Maybe the share price is just taking a breather while the business executes on its growth strategy. I find it very interesting to look at share price over the long term as a proxy for business performance. But to truly gain insight, we need to consider other information, too.
