It might seem bad, but the worst that can happen when you buy a stock (without leverage) is that its share price goes to zero. But if you buy shares in a really great company, you can more than double your money. For instance the Potbelly Corporation (NASDAQ:PBPB) share price is 141% higher than it was three years ago. How nice for those who held the stock! Also pleasing for shareholders was the 60% gain in the last three months.
Since the stock has added US$54m to its market cap in the past week alone, let's see if underlying performance has been driving long-term returns.

While markets are a powerful pricing mechanism, share prices reflect investor sentiment, not just underlying business performance. 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).
Potbelly became profitable within the last three years. Given the importance of this milestone, it's not overly surprising that the share price has increased strongly.
The image below shows how EPS has tracked over time (if you click on the image you can see greater detail).
We like that insiders have been buying shares in the last twelve months. Even so, future earnings will be far more important to whether current shareholders make money. Before buying or selling a stock, we always recommend a close examination of historic growth trends, available here..
A Different Perspective
It's good to see that Potbelly has rewarded shareholders with a total shareholder return of 82% in the last twelve months. That gain is better than the annual TSR over five years, which is 7%. Therefore it seems like sentiment around the company has been positive lately. In the best case scenario, this may hint at some real business momentum, implying that now could be a great time to delve deeper. 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.
