Marvell Technology and Flex are set to replace Campbell's and Pool Corp. in the S&P 500 on June 22nd. This means massive index funds will be forced to buy their stock.

## Idea

When a stock gets added to the S&P 500, automated funds that track the index are forced to buy millions of shares, regardless of the price. Marvell Technology is joining the index on June 22nd. This guaranteed wave of forced buying typically pushes the stock's price up in the days leading into the switch.
