Stem (NYSE:STEM) delivers shareholders stellar 223% return over 1 year, surging 17% in the last week alone

Unless you borrow money to invest, the potential losses are limited. But when you pick a company that is really flourishing, you can make more than 100%. For example, the Stem, Inc. (NYSE:STEM) share price has soared 223% in the last 1 year. Most would be very happy with that, especially in just one year! On top of that, the share price is up 48% in about a quarter. In contrast, the longer term returns are negative, since the share price is 90% lower than it was three years ago.

To quote Buffett, 'Ships will sail around the world but the Flat Earth Society will flourish. There will continue to be wide discrepancies between price and value in the marketplace...' 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 Stem grew its earnings per share, moving from a loss to a profit.

The result looks like a strong improvement to us, so we're not surprised the market likes the growth. Inflection points like this can be a great time to take a closer look at a company.

A Different Perspective

It's nice to see that Stem shareholders have received a total shareholder return of 223% over the last year. Notably the five-year annualised TSR loss of 14% per year compares very unfavourably with the recent share price performance. We generally put more weight on the long term performance over the short term, but the recent improvement could hint at a (positive) inflection point within the business. 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.
