Over the last month the electroCore, Inc. (NASDAQ:ECOR) has been much stronger than before, rebounding by 32%. But will that repair the damage for the weary investors who have owned this stock as it declined over half a decade? Probably not. Indeed, the share price is down a whopping 72% in that time. It's true that the recent bounce could signal the company is turning over a new leaf, but we are not so sure. The important question is if the business itself justifies a higher share price in the long term.

Now let's have a look at the company's fundamentals, and see if the long term shareholder return has matched the performance of the underlying business.

electroCore isn't currently profitable, so most analysts would look to revenue growth to get an idea of how fast the underlying business is growing. Shareholders of unprofitable companies usually desire strong revenue growth. Some companies are willing to postpone profitability to grow revenue faster, but in that case one would hope for good top-line growth to make up for the lack of earnings.

In the last half decade, electroCore saw its revenue increase by 45% per year. That's well above most other pre-profit companies. So on the face of it we're really surprised to see the share price has averaged a fall of 11% each year, in the same time period. It could be that the stock was over-hyped before. We'd recommend carefully checking for indications of future growth - and balance sheet threats - before considering a purchase.

We consider it positive that insiders have made significant purchases in the last year. Even so, future earnings will be far more important to whether current shareholders make money. This free report showing analyst forecasts should help you form a view on electroCore

A Different Perspective

It's nice to see that electroCore shareholders have received a total shareholder return of 46% over the last year. That certainly beats the loss of about 11% per year over the last half decade. The long term loss makes us cautious, but the short term TSR gain certainly hints at a brighter future. 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.
