Carvana's Stock Surges, Leaving Wall Street and Short Sellers in the Dust.

Online used car dealer Carvana's stock has surged more than 400% this year, making it the second-best-performing stock on the market. Despite the company's $6.8 billion debt, it has managed to improve profitability faster than expected, leading to a positive EBITDA. However, Carvana's stock is difficult to value due to its stage of turnaround and high percentage of shares sold short. While Wall Street analysts have mixed opinions on the stock, the upside potential still outweighs the downside risk.
