Nearest Resistance: $8 Nearest Support: $4.30 Catalyst: FDA Decision >>5 Stocks Under $10 Set to SoarIdenix Pharmaceuticals ( IDIX) is getting shellacked today, after announcing that the FDA was placing a traial for its lead hepatitis C compound on hold. While Idenix's compound didn't have any issues, a similar compound under trial from Bristol-Myers Squibb ( BMY) did cause a serious health issue in at least one patient. The similarities between the drugs are enough to suspend IDIX's contender -- and send shares down 30% today. Idenix is the prototypical falling knife here. Today's gap down is a big move lower for shares, but it's not necessarily any sort of a bottom at this point. Opportunistic buyers should wait for shares to catch a bid before trying to jump on a bargain opportunity. The nearest meaningful support level is the stock's 52-week low at $4.30.
