The Nasdaq-100 is a collection of 100 of the largest stocks listed on the Nasdaq exchange. While the index has lost 11% in the month of November, its bottom 10 companies have seen their stock prices fall even further.

Of course, a stock's price can drop for reasons both significant (e.g., the emergence of a more powerful competitor) and insignificant (e.g., tax selling). Hence, a large drop in stock price could offer a unique buying opportunity, but it could also present a value trap.

That's why we've paired the 10 biggest Nasdaq-100 losers for the month of November with the intelligence of our 120,000-member-strong Motley Fool CAPS community. Each company's CAPS rating should offer some insight into how our community views the company. As always, though, you should conduct your own fundamental research.
