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.
|Feb. 3||Weekly Loss||My Watchlist|
MannKind was the market's biggest loser, shedding a little more than a third of its value after announcing a dilutive stock offering. MannKind's run into a few speed bumps -- and apparently now a cash crunch -- in getting its inhaled insulin Afrezza on the market.
Hyperdynamics was the Big Board's biggest decliner. It too announced a dilutive share offering at a healthy market discount, and that was enough to prompt Howard Weil to downgrade shares of the oil explorer.
Small-box retailer RadioShack got even smaller after announcing dreadful preliminary results for the holiday quarter. Thinning gross margins find the consumer electronics chain targeting a profit of no more than $0.13 a share for the holiday quarter, well short of the $0.37 a share that analysts were targeting.
ShoreTel may have posted a surprising quarterly profit, but it was the provider of Web-based telephony's bleak near-term outlook that led to investors hanging up on the stock.
Finally, Polypore took a hit after a former customer revealed plans to compete with the company by building its own plant to make filtration membranes. A couple of analysts downgraded Polypore on the news.
