Wall Street was a scene of explosive optimism on Tuesday as a major breakthrough on the international trade front sent stocks soaring, pushing two of the three major indexes into record territory.

The Dow Jones Industrial Average rocketed up by 508 points, a stunning 1.1% gain that brought the index tantalizingly close to its first record close since early December. The rally was broad-based, with the S&P 500 climbing 0.8% and the tech-heavy Nasdaq Composite adding 0.6%—both closing at fresh all-time highs.

The powerful surge was ignited by a major announcement from President Donald Trump, who confirmed that new trade pacts had been secured with Japan, Indonesia, and the Philippines. The news sent a wave of relief through the market, fueling trader hopes that a wider agreement could be reached to lower effective tariff rates ahead of a critical August 1 deadline.

However, beneath the surface of the record-setting rally, a worrying signal flashed red in the crucial technology sector. Shares of semiconductor giant Texas Instruments plunged sharply after the company's management delivered a sobering outlook. In their commentary, executives cast significant doubt on the strength of the much-anticipated recovery in the industrial and automotive markets, suggesting the rebound might not be as robust as Wall Street had eagerly priced in.

The fallout was immediate, with the negative sentiment from Texas Instruments dragging down the entire semiconductor sector. This created a stark contrast on a day of otherwise widespread gains. The anxiety was further reflected in the bond market, where yields rose, with the 2-year Treasury note climbing to 3.88% and the 10-year yield hitting 4.39%.

Not all sectors joined the celebration. Defensive areas of the market took a backseat, with utilities and consumer staples emerging as the biggest laggards in the S&P 500. The day's mixed performance sets a tense stage for a blockbuster week of earnings, with investors now anxiously awaiting reports from titans like Alphabet and Tesla to determine if the market's optimism is justified or if Texas Instruments' warning is a sign of trouble ahead.
