It's Nvidia earnings day:
The options market is currently pricing in a 6.1% post-earnings implied move in Nvidia, $NVDA.
This implies a swing of ~$270 BILLION of market cap after the close today.
This is more than the market cap of 95% of S&P 500 companies.
It's also more than the market cap of all but 41 public companies in the world.
Buckle up.
