Earlier quoted context omitted.
>All that an inclusion of these new companies would accomplish is a bailout of their stockholders by pension funds and ETFs where millions of regular people shoulder all the downside risk. Carvana is the poster child for this. It's astonishing that a company with a history of shady practices, and that has yet to offer a convincing explanation for why it is not a scam, is part of the S&P 500.
what's the argument for it being a scam?
They're an outlier in the industry in terms of profit per car. But they don't actually get revenue from selling cars, their revenue comes from selling car loans. So they're making the additional margin on the financing. They are also famous for not turning down loan applications. So putting the pieces together, it seems like they are selling high risk loans at a healthy profit. Which brings up the question of who is buying those loans. They don't disclose the buyers, but claim that those buyers are not controlled by Carvana or its parent. Given the history of fraud, it's hard to take those claims at face value. The suspicion is that they are selling the loans to family-controlled shell companies and leveraging the stock to finance the scheme.
