When you buy shares in a company, it's worth keeping in mind the possibility that it could fail, and you could lose your money. But when you pick a company that is really flourishing, you can make more than 100%. For example, the Micron Technology, Inc. (NASDAQ:MU) share price has soared 105% in the last half decade. Most would be very happy with that. In the last week shares have slid back 4.3%.

Although Micron Technology has shed US$4.9b from its market cap this week, let's take a look at its longer term fundamental trends and see if they've driven returns.

It's fair to say that the TSR gives a more complete picture for stocks that pay a dividend. As it happens, Micron Technology's TSR for the last 5 years was 109%, which exceeds the share price return mentioned earlier. This is largely a result of its dividend payments!

A Different Perspective

Micron Technology provided a TSR of 30% over the year (including dividends). That's fairly close to the broader market return. Most would be happy with a gain, and it helps that the year's return is actually better than the average return over five years, which was 16%. Even if the share price growth slows down from here, there's a good chance that this is business worth watching in the long term.
