Big market gains left scores of top-rated stocks at new highs, including breakouts in several sectors. Insys Therapeutics (INSY) broke out of a cup-without-handle base, although volume was merely average. Shares of the biotech climbed 0.81 to 34.26. The rise left the stock slightly above its 34.03 buy point. The stock’s relative strength line hit a new high — a bullish sign for the breakout if volume can come into the stock.
