These companies are allowed to go public and anyone can buy their shares.
Since the start, the S&P 500 has had a simple and consistent profitability screen. Your company must be GAAP profitable in the past quarter, as well as for your past four quarters when summed up.
The S&P 500 committee isn’t targeting these companies. They are simply choosing to keep the rules they’ve had in the beginning. And when these companies can deliver one year of profitability, like every single company added to the S&P 500 since inception, they too can join the index.
Refusing to change longstanding rules that make sense (remember: companies are supposed to be profitable!!) isn’t unfair.
