If you buy and hold a stock for many years, you'd hope to be making a profit. But more than that, you probably want to see it rise more than the market average. But Turtle Beach Corporation (NASDAQ:HEAR) has fallen short of that second goal, with a share price rise of 75% over five years, which is below the market return. On a brighter note, more newer shareholders are probably rather content with the 53% share price gain over twelve months.

With that in mind, it's worth seeing if the company's underlying fundamentals have been the driver of long term performance, or if there are some discrepancies.

There is no denying that markets are sometimes efficient, but prices do not always reflect 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.

During the last half decade, Turtle Beach became profitable. That would generally be considered a positive, so we'd hope to see the share price to rise.

The company's earnings per share (over time) is depicted in the image below (click to see the exact numbers).

We consider it positive that insiders have made significant purchases in the last year. Even so, future earnings will be far more important to whether current shareholders make money. This free interactive report on Turtle Beach's earnings, revenue and cash flow is a great place to start, if you want to investigate the stock further.

A Different Perspective

We're pleased to report that Turtle Beach shareholders have received a total shareholder return of 53% over one year. Since the one-year TSR is better than the five-year TSR (the latter coming in at 12% per year), it would seem that the stock's performance has improved in recent times. Someone with an optimistic perspective could view the recent improvement in TSR as indicating that the business itself is getting better with time. 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. Even so, be aware that Turtle Beach is showing 4 warning signs in our investment analysis , and 1 of those doesn't sit too well with us...
