Monday's Small-Cap Winners & Losers

Progressive Gaming International (PGIC Quote) plummeted more than 26% Monday after the Las Vegas-based maker of gambling equipment announced "irregular trading volume" in its stock Friday.

The irregular trading came just before the media published "specific excerpts related to the company's risk factors" from its 2006 year-end financials. Progressive intends to report this incident to regulators. The filing contained a warning that bankruptcy may be in the cards due to a $39 million verdict from an antitrust lawsuit. Shares were losing $1.31, to $3.62, in recent trading.

CV Therapeutics (CVTX Quote) slid after an analyst with Deutsche Bank cut the company's rating to sell from hold, forecasting that the drugmaker's value will drop more than 75% over the coming year after it publicizes complete late-phase results for Ranexa, its existing angina drug, which had undergone extensive testing for a new indication. Earlier this month shares plummeted on disappointing preliminary results. Today the stock was sinking $2.04, or 24%, to $6.52.
