Investors should take note of the current market trends as the S&P 500 and Nasdaq have been on track for a winning week, with new records being set earlier. AI technology continues to dominate the market, with Anthropic debuting its powerful artificial intelligence model. In the biopharmaceutical sector, Gilead Sciences reported 100% effectiveness in its experimental HIV prevention shot, potentially offering a more convenient option for those at risk. However, Trump Media, the company behind Truth Social, saw its shares plummet by 15% following a sell-off, highlighting the volatility of the market. It is essential for investors to stay informed and prepared for fluctuations as they navigate the trading day.
