Canaan (NASDAQ:CAN) shareholders are up 20% this past week, but still in the red over the last three years

It is doubtless a positive to see that the Canaan Inc. (NASDAQ:CAN) share price has gained some 47% 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 71% in that time. So it's about time shareholders saw some gains. The thing to think about is whether the business has really turned around.

The recent uptick of 20% could be a positive sign of things to come, so let's take a look at historical fundamentals.

AI is about to change healthcare. These 20 stocks are working on everything from early diagnostics to drug discovery. The best part - they are all under $10bn in marketcap - there is still time to get in early.

Because Canaan made a loss in the last twelve months, we think the market is probably more focussed on revenue and revenue growth, at least for now. Generally speaking, companies without profits are expected to grow revenue every year, and at a good clip. As you can imagine, fast revenue growth, when maintained, often leads to fast profit growth.

In the last three years Canaan saw its revenue shrink by 49% per year. That means its revenue trend is very weak compared to other loss making companies. The swift share price decline at an annual compound rate of 20%, reflects this weak fundamental performance. 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

Canaan shareholders are down 12% for the year, but the market itself is up 19%. 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 9% 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. It's always interesting to track share price performance over the longer term. But to understand Canaan better, we need to consider many other factors.
