The T-Rex 2X Inverse Tesla Daily Target ETF (TSLZ) surged 6.17% to close at $2.41 on December 20, as Tesla's stock fell 3.59% to $420.50 amid a volatile trading session. Tesla's decline was influenced by a combination of factors, including a significant 40.9% drop in European sales in November and a recall of nearly 700,000 vehicles in the U.S. due to a tire pressure monitoring system issue. Despite a recent rally following Donald Trump's re-election, Tesla's stock faced pressure from concerns over its high valuation and the challenges in achieving full autonomy for its vehicles. The market's reaction was also shaped by the expiration of equity options, which contributed to the stock's volatility.
