Tesla Inc.'s stock experienced a significant surge in after-hours trading, reaching new all-time highs. The stock price hit nearly $427, with some traders predicting further increases to $450. This bullish trend was highlighted by various market observers, with one user noting that Tesla's stock had doubled since its earnings report low in October. Meanwhile, Uber Technologies Inc. faced a different market sentiment, closing down 5.82% and trading about 30% below its all-time high. Uber's decline was attributed to several factors, including hedge fund holders offloading shares and the company's stock being close to a 52-week low. However, Uber's stock saw a slight recovery in after-hours trading, possibly influenced by comments made during a conference. Specific details include Uber's stock being down 28% from recent highs, trading at a Forward EV/EBIT of ~26x, and being in the $57 - $62 zone, which some investors see as an opportunity for the stock to reach $80 again.
