Contrarian take

Many Magnificent 7 companies are currently unable to execute share buybacks because free cash flow is being redirected entirely into capex, removing a key historical support for their stock prices.

“A lot of the mag 7 is not able to do buybacks right now because they're using their free cash flow to invest in VEX and capback.”
