Nasdaq Races To An All-time High, As Dow, S&P 500 End Flat

The Nasdaq Composite closed at a record Thursday, during an busy day of corporate quarterly results, but the broader market ended in neutral territory as a slump in energy and questions about President Donald Trump's tax plan weighed on Wall Street. The Nasdaq Composite ended up 0.4% at 6,048, marking a fresh record for the tech-heavy index--its second all-time closing high for the week. The Dow Jones Industrial Average closed at break-even levels at 20,981, as did the S&P 500 index at 2,388. Energy stocks declined 1.1%, representing the worst performer among the S&P 500's 11 sectors as U.S. crude-oil prices settled at the lowest level in a month. Subdued trade in the broader market came as analysts said Trump's tax proposal delivered Wednesday afternoon, was light on specifics and failed to address the question of how the proposed cuts would be funded. In corporate news, American Airlines Group Inc. shares slumped after reporting disappointing first-quarter results. Investors were also awaiting a slew of earnings for tech names, including those for Google-parent Alphabet Inc. , Microsoft Inc. and Amazon Inc. , all reporting after Thursday's close of regular trade.
