Although we don't believe in timing the market or panicking over market movements, we do like to keep an eye on big changes -- just in case they're material to our investing thesis.
What: Shares of pharmaceuticals specialist Warner Chilcott (NAS: WCRX) rose more than 10% in early trading and remained up nearly that much at the close.
So what: We don't know exactly what caused the rally, but an ongoing unwinding of short positions in the stock may be partly to blame. On Monday, Reuters reported that Warner enjoyed the second-largest decline in short interest during the second-half of August.
Now what: Shorts redeemed more than 4.4 million shares between Aug. 15 and 31, down 58%. Capital IQ shows similar data. The implication? A massive short squeeze has fueled returns recently. Fundamentals and valuation will have to do the job over the long term. Do you agree? Disagree? Please weigh in using the comments box below.
