Semler Scientific, Inc. (NASDAQ:SMLR) shareholders might be concerned after seeing the share price drop 18% in the last week. But that doesn't change the reality that over twelve months the stock has done really well. In that time we've seen the stock easily surpass the market return, with a gain of 81%.

Although Semler Scientific has shed US$60m from its market cap this week, let's take a look at its longer term fundamental trends and see if they've driven returns.

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...' 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.

During the last year Semler Scientific grew its earnings per share (EPS) by 56%. The share price gain of 81% certainly outpaced the EPS growth. So it's fair to assume the market has a higher opinion of the business than it a year ago.

It's probably worth noting that the CEO is paid less than the median at similar sized companies. It's always worth keeping an eye on CEO pay, but a more important question is whether the company will grow earnings throughout the years.

A Different Perspective

We're pleased to report that Semler Scientific shareholders have received a total shareholder return of 81% over one year. Notably the five-year annualised TSR loss of 0.4% per year compares very unfavourably with the recent share price performance. This makes us a little wary, but the business might have turned around its fortunes. 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.
