5 of Last Week's Biggest Losers

There's never a shortage of losers in the stock market. Let's take a closer look at five of this past week's biggest sinkers.

Let's start with Tremor Video. It was the biggest loser on the New York Stock Exchange, shedding nearly half of its value on Friday alone after posting disappointing quarterly results. Revenue growth fell short of analyst targets, and then it warned of a sharp sequential decline on the top line. Wall Street was braced for improvement. The video advertising specialist went public in June, and the market hates when rookies mess up. It makes it seem as if retail investors were duped into buying into a debutante that was actually peaking. In short, Tremor Video's lost the market's confidence.

BlackBerry got squeezed after the smartphone pioneer ousted its CEO and called off the strategic review to entertain buyout offers. Investors hoping for an exit strategy or at least an asset sale were disappointed to see BlackBerry move to raise money and try to make it on its own. This just doesn't seem like a feasible strategy when sales are plunging.

Tesla hit the brakes after posting a quarterly report that was a bit light on Model S deliveries. Reports that a third Tesla caught fire also hurt the company that uses its car's high safety rating as part of its marketing message.

Calumet Specialty Products slipped after missing Wall Street estimates for the third quarter in a row. The company stunned the market by posting a loss when a healthy profit was expected. Calumet's soft report was the handiwork of higher input costs that tightened up the margins for fuel and specialty products.

Finally, we have Annaly Capital Management going the wrong way. The mortgage REIT posted a smaller profit than Wall Street was expecting, and just as troubling, we're seeing Annaly's book value continue to contract sharply. Book value per share has fallen from $16.70 to $12.70 over the past year.
