Five super falls -- one superball
There are no two ways about it. If you owned any of the five stocks named above last week, you're significantly poorer for it today. So what went wrong?

Let's see. F5's decline seems a simple function of gravity reasserting itself after a strong surge last week. At Great Panther, there appears to have been a hiccup in silver prices that briefly knocked the wind out of the stock (before it resumed its inexorable climb).

But in most cases, the primary factor behind stock weakness last week appears to have been "earnings." On Wednesday, MIPS Tech failed to deliver on its promise to steal market share from ARM Holdings (Nasdaq: ARMH), and fell 10% shy of earnings targets. Then Akamai missed earnings, growing revenue only 15% and translating that into a mere 9% improvement in profits. Last but not least, Teradyne took a tumble when it beat earnings but warned that Wall Street's expectations for the current quarter may be too aggressive.

Of the five, I'm probably more inclined to invest in the company that underpromises on future quarters, while overdelivering on current earnings. And I'm not the only one.

The bull case for Teradyne
CAPS member tuscanstar has been bullish on Teradyne since the summer of 2009, when the company won a contract to provide equipment for chip maker Qualcomm (Nasdaq: QCOM). Also attractive: "its relatively cheap price compared to its fundematal strength." As it turned out, this CAPS member was right -- beating the market by 46 percentage points on the pick.

CAPS member EnigmaDude says the "stock is being punished for a weak Q2 outlook after reporting good Q1 results." According to CAPS member ksiren, this just gives us a chance to repeat tuscanstar's feat, because once again Teradyne is showing "great growth" and selling for a "low valuation" with "a solid balance sheet."

I agree. At its current market cap, Teradyne shares fetch a shockingly cheap P/E ratio of just 7. They're even cheaper when valued on the company's $480 million in trailing free cash flow. The P/FCF ratio on this stock is a mere 6.2, while the company's solid balance sheet, loaded with $650 million in net cash, gives Teradyne an enterprise value-to-free cash flow ratio of less than 5. At the risk of overstating the case, investors are practically giving the stock away.

Time to chime in
Granted, Teradyne's earnings warning last week puts in question the 16% long-term growth estimate that analysts have assigned the company. But that's OK with me. The way I look at this, at today's prices Teradyne would be a bargain at half that growth rate.

Of course, that's just my opinion. What's yours?
