While it may not be enough for some shareholders, we think it is good to see the Incyte Corporation (NASDAQ:INCY) share price up 11% in a single quarter. But over the last half decade, the stock has not performed well. After all, the share price is down 22% in that time, significantly under-performing the market.

After losing 5.5% this past week, it's worth investigating the company's fundamentals to see what we can infer from past performance.

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.

During the five years over which the share price declined, Incyte's earnings per share (EPS) dropped by 38% each year. This fall in the EPS is worse than the 5% compound annual share price fall. So the market may previously have expected a drop, or else it expects the situation will improve. The high P/E ratio of 420.09 suggests that shareholders believe earnings will grow in the years ahead.

A Different Perspective

Incyte shareholders gained a total return of 11% during the year. But that return falls short of the market. But at least that's still a gain! Over five years the TSR has been a reduction of 4% per year, over five years. So this might be a sign the business has turned its fortunes around. 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. Consider for instance, the ever-present spectre of investment risk. We've identified 2 warning signs with Incyte , and understanding them should be part of your investment process.
