Dow rises 0.7% as bitcoin hits $77K; tech stocks slide amid bond repurchase plan and Jackson Hole watch.

U.S. stock markets saw modest gains Friday with the Dow Jones up 0.7%, led by financials, while the S&P 500 and Nasdaq rose 0.4% and 0.3% respectively. Bitcoin surged to $77,000, marking its strongest weekly gain in nearly three years, contrasting with a six-day decline in tech stocks including Nvidia and Apple. Treasury Secretary Scott Bessent announced an expanded bond repurchase program to address Treasury yield volatility, but yields quickly rose again. Investors are now focused on the upcoming Jackson Hole Symposium, Nvidia's earnings report, and U.S. economic strategies toward Iran, signaling a cautious but resilient market environment.
