Shares of Apple fell more than 3% Friday and are down for the whole week too. Worries of soft demand for iPhones --particularly the iPhone X -- hit chip stocks hard too. But Amazon, Netflix and other big techs are still up for the week.
The main U.S. stock indexes hit record intraday highs on Monday, with the S&P 500 topping $20 trillion in combined market-capitalization for the first time ever, as the "Trump trade" jump-started on renewed optimism about the economy. President Donald Trump vowed last week to make a major tax announcement in the next few weeks, rekindling a rally that has stalled amid concerns over Trump's protectionist stance and lack of clarity on policy reforms. The S&P has surged 8.3 percent since Trump's Nov. 8 election through Friday's close, fueled by expectations Trump would lower corporate taxes, reduce regulations and increase infrastructure spending.
