Should You Be Adding Silicon Motion Technology (NASDAQ:SIMO) To Your Watchlist Today?

It's only natural that many investors, especially those who are new to the game, prefer to buy shares in 'sexy' stocks with a good story, even if those businesses lose money. And in their study titled Who Falls Prey to the Wolf of Wall Street?' Leuz et. al. found that it is 'quite common' for investors to lose money by buying into 'pump and dump' schemes.

If, on the other hand, you like companies that have revenue, and even earn profits, then you may well be interested in Silicon Motion Technology (NASDAQ:SIMO). Now, I'm not saying that the stock is necessarily undervalued today; but I can't shake an appreciation for the profitability of the business itself. In comparison, loss making companies act like a sponge for capital - but unlike such a sponge they do not always produce something when squeezed.

How Fast Is Silicon Motion Technology Growing?

The market is a voting machine in the short term, but a weighing machine in the long term, so share price follows earnings per share (EPS) eventually.

As a tree reaches steadily for the sky, Silicon Motion Technology's EPS has grown 28% each year, compound, over three years. If the company can sustain that sort of growth, we'd expect shareholders to come away winners.
