It is doubtless a positive to see that the Alector, Inc. (NASDAQ:ALEC) share price has gained some 35% in the last three months. But that is meagre solace in the face of the shocking decline over three years. The share price has sunk like a leaky ship, down 77% in that time. Arguably, the recent bounce is to be expected after such a bad drop. Of course the real question is whether the business can sustain a turnaround.

Since shareholders are down over the longer term, lets look at the underlying fundamentals over the that time and see if they've been consistent with returns.

Given that Alector didn't make a profit in the last twelve months, we'll focus on revenue growth to form a quick view of its business development. Shareholders of unprofitable companies usually desire strong revenue growth. As you can imagine, fast revenue growth, when maintained, often leads to fast profit growth.

In the last three years Alector saw its revenue shrink by 25% per year. That means its revenue trend is very weak compared to other loss making companies. And as you might expect the share price has been weak too, dropping at a rate of 21% per year. Never forget that loss making companies with falling revenue can and do cause losses for everyday investors. There is a good reason that investors often describe buying a sharply falling stock price as 'trying to catch a falling knife'. Think about it.

A Different Perspective

Alector shareholders are down 7.1% for the year, but the market itself is up 30%. However, keep in mind that even the best stocks will sometimes underperform the market over a twelve month period. Unfortunately, longer term shareholders are suffering worse, given the loss of 11% doled out over the last five years. We would want clear information suggesting the company will grow, before taking the view that the share price will stabilize. 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. To that end, you should be aware of the  3 warning signs  we've spotted with Alector .
