This week on D-Risk Investing, we tackle Carvana's (CVNA) mind-bending rally. After nearly collapsing, the online used car giant is joining the S&P 500 at a jaw-dropping 170x forward P/E, while its fundamental valuation sits four times lower. Is this equity a genuine, debt-slashing turnaround story justified by massive operational leverage, or is the stock price running on pure, speculative momentum and short-squeeze fuel? We break down what the technical picture, options market, and a $110 fair value estimate are really signaling—and what’s next for investors.
