The top 10 stocks held by institutions have been a mixed bag of returns so far in 2016. Alphabet (formerly Google) and Apple each were down more than 2%, while Microsoft had a modest gain. Johnson & Johnson was the top performer as investors move toward the safer ends of the market amid uncertainty. Gilead fell from its high nearly a year ago after earnings missed expectations and questions surrounding the firm's future profitability gained traction.
The broader U.S. equity markets are up approximately 6% over the same period.
