Worse than expected
  The sale of shares by a key executive like the Chief Financial Officer, even if pre-planned under a Rule 10b5-1 plan, can be interpreted by the market as a less positive signal regarding the company's near-term stock performance or the executive's personal outlook on the stock's future appreciation.
