Worth a closer look

  • Bought by the CEO, one of the two people with the fullest view of the company.
  • 3 different insiders bought in the last 90 days.

Reasons for caution

  • Other insiders sold $3.7M in the same 90 days, more than was bought.
  • Similar past buys beat the S&P 500 only 35% of the time (86 cases); the typical one trailed it by 7.0%.
