Electro Scientific said its order backlog is the highest it has been in six years, which is pre-recession. The balance sheet remains solid; Electro Scientific ended the quarter with $185 million, or $6.32 per share, in cash (excluding restricted cash) and short-term investments, and no debt.

It currently trades at book value, and at just 1.44 times net current asset value, which is very cheap in my book. The company also initiated an 8-cent quarterly dividend in 2012 and currently yields 3%. There is also an active stock buyback program.

Those are small rays of light from three companies. While not enough to declare a return to brighter economic times, they're still slightly encouraging -- even for a skeptic.

Back to Facebook. The stock's woes have little to do with the economy. Expectations were simply too high, and any negative news will continue to weigh on the shares. Even considering the aftermarket drubbing the stock suffered yesterday, this is still a company with a $48 billion market cap -- and one that is unproven.
