Opko Health $OPK is under investigation for unlawful business practices.

Potential Signals:- If price can hold above $4.50, OPK would essentially hold above the 200-day simple moving average (SMA). This would complete a bullish slingshot. Then, a break above $5.00 would convince me that bulls are indeed in control.- However, failure to push above $5.00 and inability to hold above $4.50 would open up the $3.00 support.
