The Nasdaq Composite Index was trading sharply higher late-morning Friday, with the session's gains, helping to erase a weekly loss for the index, pushing it firmly in to positive territory for the week, up 0.7%. The Nasdaq most recently was 1.2% higher at 7,169 on the back of Apple Inc. hitting a record high on a report that Warren Buffett's Berkshire Hathaway Inc. acquired 75 million shares of the iPhone maker during the first three months of 2018, increasing its investment in the company. The bounce in shares of the most highly valued company in the world, helped to push the broader market high, but had a decided effect on the market-value weighted Nasdaq. Meanwhile, the Dow Jones Industrial Average [: DJIA], where Apple is also a major component, was rallying, up 214 points, or 0.9%, at 24,144, while the S&P 500 index climbed 0.7% at 2,649.
