Strong week for Semtech (NASDAQ:SMTC) shareholders doesn't alleviate pain of three-year loss

In this article:

Semtech Corporation (NASDAQ:SMTC) shareholders will doubtless be very grateful to see the share price up 44% in the last quarter. But only the myopic could ignore the astounding decline over three years. The share price has sunk like a leaky ship, down 73% in that time. Arguably, the recent bounce is to be expected after such a bad drop. Only time will tell if the company can sustain the turnaround.

On a more encouraging note the company has added US$104m to its market cap in just the last 7 days, so let's see if we can determine what's driven the three-year loss for shareholders.

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 flawed but reasonable way to assess how sentiment around a company has changed is to compare the earnings per share (EPS) with the share price.

Over the three years that the share price declined, Semtech's earnings per share (EPS) dropped significantly, falling to a loss. Since the company has fallen to a loss making position, it's hard to compare the change in EPS with the share price change. However, we can say we'd expect to see a falling share price in this scenario.

We like that insiders have been buying shares in the last twelve months. Even so, future earnings will be far more important to whether current shareholders make money. Before buying or selling a stock, we always recommend a close examination of historic growth trends, available here..

A Different Perspective

Semtech shareholders are down 35% for the year, but the market itself is up 23%. Even the share prices of good stocks drop sometimes, but we want to see improvements in the fundamental metrics of a business, before getting too interested. Regrettably, last year's performance caps off a bad run, with the shareholders facing a total loss of 10% per year over five years. We realise that Baron Rothschild has said investors should "buy when there is blood on the streets", but we caution that investors should first be sure they are buying a high quality business. It's always interesting to track share price performance over the longer term. But to understand Semtech better, we need to consider many other factors. Consider for instance, the ever-present spectre of investment risk. We've identified 2 warning signs with Semtech (at least 1 which is potentially serious) , and understanding them should be part of your investment process.
