"Over the past few weeks, shares in e-commerce outsource provider Digital River (Nasdaq: DRIV - News) have been selling off after reaching a 52-week high of $44 in early December. Helping to push the stock downward was news that Computer Associates (NYSE: CA - News) was giving away one-year trials of its firewall and security software for free. It was seen as a big threat to competitor Symantec (Nasdaq: SYMC - News), which is a major customer of Digital River, providing 27% of revenues in 2003."
