What happened
After a brutal 2022, almost no one expected a rebound. Then ChatGPT set off an AI arms race, and Microsoft poured $10 billion into OpenAI.
Nvidia's May 2023 earnings guidance stunned Wall Street: the stock jumped 24% in a single day, added $184 billion in market value, and briefly joined the $1 trillion club. Nvidia tripled over 2023 as the 'Magnificent Seven' carried the whole market. Its CEO called it 'the iPhone moment of AI.'
Spotting the boom was easy. The hard part was deciding when to pile in — and when to take profit before the inevitable pullbacks.
