 Today marks the end of the first half of 2024 on Wall Street. Three major indexes up over the past six months. The Nasdaq leading the way thanks to the AI tech boom. The index up around 20% for the year so far. NVIDIA leading that charge up more than 150% since January. NVIDIA down slightly today. Still late week gains enough to carry the chip maker into positive territory. NVIDIA narrowly avoiding its second straight weekly loss.
