Why Novocure Stock Sank Today

Shares of Novocure (NASDAQ: NVCR) were sinking 9.2% as of 3:30 p.m. on Tuesday. The oncology therapy company didn't announce any news, so why did the stock fall on a day when the overall market soared? The most likely reason is that some investors decided to lock in profits after Novocure's year-to-date gain of nearly 60% as of the market close on Monday.
