Apple Inc. shares surged as high as $230 on Friday, putting the stock on course for its first close above its 200-day moving average since early March, according to real-time market data. The rally marks a sharp recovery of almost 30 points from the post-earnings dip recorded earlier in the week. The iPhone maker has climbed about 12%–15% since Monday, a move that would rank as its strongest weekly advance in roughly four years and its best three-day relative performance since 2008. Apple’s strength helped lift major equity benchmarks, with the Dow Jones Industrial Average, Nasdaq Composite and S&P 500 all trading higher as investors rotated back into the megacap stock.
