Canadian Solar Inc. (NASDAQ:CSIQ) shareholders might understandably be very concerned that the share price has dropped 42% in the last quarter. But that doesn't change the fact that the returns over the last year have been very strong. Indeed, the share price is up an impressive 110% in that time. So we think most shareholders won't be too upset about the recent fall. Investors should be wondering whether the business itself has the fundamental value required to continue to drive gains.

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 way to examine how market sentiment has changed over time is to look at the interaction between a company's share price and its earnings per share (EPS).

During the last year, Canadian Solar actually saw its earnings per share drop 15%.

This means it's unlikely the market is judging the company based on earnings growth. Indeed, when EPS is declining but the share price is up, it often means the market is considering other factors.

We think that the revenue growth of 8.5% could have some investors interested. We do see some companies suppress earnings in order to accelerate revenue growth.

A Different Perspective

We're pleased to report that Canadian Solar shareholders have received a total shareholder return of 110% over one year. That gain is better than the annual TSR over five years, which is 15%. Therefore it seems like sentiment around the company has been positive lately. Someone with an optimistic perspective could view the recent improvement in TSR as indicating that the business itself is getting better with time. While it is well worth considering the different impacts that market conditions can have on the share price, there are other factors that are even more important.
