24/7 Wall St.

With a huge trading year in the books last Friday, it’s no surprise that many top executives took advantage of the best December since 2010 and sold stock. This past week we noticed many trades on the top technology companies, and given the solid advances in the stocks this year, it was no surprise. In addition, with first quarter-earnings in about two weeks, most insider windows for transactions will be closing soon.

We cover insider selling each week at 24/7 Wall St., and we like to remind readers that just because an individual or 10% institutional owner sells stock, that is no cause for immediate alarm. Many top executives, and even directors, are compensated with stock and often sell just to diversify portfolios or purchase other assets.
