Chip equipment maker OmniVision has plenty of fund fans. But only one of its top five recent buyers commands at least a four-star rating from Morningstar.

Allow me to introduce you to Hussman Strategic Growth (HSGFX), a no-load winner that's anything but your typical fund. Strategic Growth, you see, is what's called a hybrid fund, which are like hedge funds in that they combine long and short positions to form a defensive portfolio that profits in both up and down markets.

Few have performed better in that role than manager John Hussman. Over the past year, with markets imploding around the globe, Strategic Growth is up more than 4%. How did he do it? A heavy dose of defensive stocks. Here's a look at the top five in Hussman's portfolio:

Notice the balance Hussman maintains. Just when you think he's an all-value guy with a deep interest in commodities, bam! ... he springs a growth stock, Research In Motion, on you. But even RIM may be cheaper you think, according to CAPS investor kUO0830. Quoting from last week's pitch:

The stock is cheap relative to where it was at towards the end of 2007. The BlackBerry is still being sold in tremendous numbers quarter after quarter. Research In Motion [has] beat earnings estimates quarter after quarter. The stock is cheap compared to how much the company is worth.

Numbers back up that assertion. Reuters estimates confer upon Research In Motion a 0.88 PEG ratio for calendar 2008 and a 0.65 ratio for 2009. In each case, analysts appear to believe the stock is undervalued.

I'll add that while the iPhone appears to have slapped Palm (Nasdaq: PALM) and stalled Motorola, BlackBerry sales continue unabated. Doesn't that deserve a premium of some sort? I think so, yet there doesn't appear to be one attached to RIM's share price.

But that's my take. What's yours? Would you own Research In Motion or any of the stocks in Hussman Strategic Growth's portfolio, at today's prices? Log in to CAPS today, and let us know what you think. It's 100% free to participate.
