BlackLine, Inc. (NASDAQ:BL) shareholders should be happy to see the share price up 20% in the last quarter. But that is small recompense for the exasperating returns over three years. Indeed, the share price is down a tragic 53% in the last three years. So the improvement may be a real relief to some. The rise has some hopeful, but turnarounds are often precarious.

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.

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. By comparing earnings per share (EPS) and share price changes over time, we can get a feel for how investor attitudes to a company have morphed over time.

BlackLine became profitable within the last five years. That would generally be considered a positive, so we are surprised to see the share price is down. So it's worth looking at other metrics to try to understand the share price move.

We note that, in three years, revenue has actually grown at a 16% annual rate, so that doesn't seem to be a reason to sell shares. This analysis is just perfunctory, but it might be worth researching BlackLine more closely, as sometimes stocks fall unfairly. This could present an opportunity.

A Different Perspective

BlackLine provided a TSR of 12% over the last twelve months. But that was short of the market average. On the bright side, that's still a gain, and it's actually better than the average return of 4% over half a decade This could indicate that the company is winning over new investors, as it pursues its strategy. It's always interesting to track share price performance over the longer term. But to understand BlackLine better, we need to consider many other factors.
