The CEO Follows His Director in With $2.6M

A few hours after a director stepped in, the CEO of this cancer-drug developer put down $2.6 million at $105.82, and that's the buy that carries the weight. Mark Lappe has now bought this name five times in the past year, which tells you he's not timing a bounce so much as building a position through the clinical grind. Insider buys here have worked about two-thirds of the time over 30 days, though the 90-day picture flattens out, so the edge fades if you overstay. Price is sitting below the 8-day at $114 with the 20-day underneath at $112, so the tape hasn't confirmed yet. Support is down at $86.40 if this pulls back, and that's where patience pays over chasing.
