Double-down on hot stocks? After the Great Wall Street Panic of 2008, who would dare?

Of the 103 stocks that our data source Capital IQ says doubled in 2007, 75 dropped at least 40% in 2008, including First Solar (NASDAQ:FSLR). But not all stock pickers suffered: Capital IQ also found eight stocks that posted positive gains after doubling in 2007. One, Sequenom (NASDAQ:SQNM), doubled again.

Wowsa.

In better years, the ratio would be a lot higher. Consider 2003, in which the S&P 500 rose more than 26%. Capital IQ found 301 stocks that doubled that year, 183 of which beat the market again in 2004.

In other words, hot stocks can be worth buying. Fool co-founder David Gardner, chief rebel for our Motley Fool Rule Breakers service, often buys stocks after they've become multibaggers. "I bought AOL after it quadrupled," he declared in describing the six signs of a rebel stock in the making.

A touch of Synaptics
If CAPS investors love Synaptics it's because of the netbook craze. Explained robert815 in this late January pitch:

[Synaptics] consistently outperforms the market and beats expectations. They are good amount cash on hand and bought back shares. They are riding the wave of touchscreen craze after the iPhone. They are in the Blackberry Storm and Google G1 Android phones. They are also the dominant market leader in supplying notebook touchpads, and will benefit from the increased popularity of netbooks around the world. I expect continued success as long as these trends continue.

Touchscreens are, indeed, powerful technology. But it isn't new technology. 3M invented touch-sensitive dispersive signal technology (DST) in 2002. Can Synaptics maintain momentum in a maturing market? Last month's earnings report -- in which revenue and profit both surged by more than 40% -- screams, "YES!"

Plus, this rebel, with a PEG ratio of 0.62, is priced well below its expected long-term growth estimates. That's more than enough of a margin for CAPS investor samm107.

"Synaptics is a very innovative company creating chips and sensors for electronics including PDAs, cell phones, and currently most research geared toward laptops and notebooks. I personally love the new enhanced gesture recognition and the smart touch capability," our Fool wrote in a June pitch.
