Palantir Technologies Inc. (NYSE: PLTR) declined 7% on Thursday after a flood of shares became eligible to sell for the first time. Nearly all shares are now unlocked for trading, the result of an unusual restriction placed on stockholders when the data software company went public. Two longtime investors said in interviews that they will hold, but at least one other, billionaire George Soros, has publicly signaled his plans to exit. Palantir’s stock has more than tripled since going public. Palantir released its quarterly earnings results on Thursday. Despite exceeding analysts’ expectations on revenue and other measures, concerns about growth prospects and the lockup expiration sent the stock 7,05% lower.
