Context
Sales by corporate officers can be routine (diversification, liquidity needs, scheduled plans) and do not by themselves indicate management’s view of the company’s prospects. This transaction is relatively small in dollar terms. For a fuller picture, compare with other recent insider trades and the insider’s total holdings disclosed in Cogent’s full Form 4.
