The T-Rex 2X Inverse Tesla Daily Target ETF (TSLZ) surged 9.77% to close at $2.19 on December 27, as Tesla Inc. (TSLA) shares fell 4.87% to $432.02 amid concerns over its ability to meet ambitious delivery targets. Tesla's stock decline was fueled by profit-taking and skepticism about achieving the 515,000 vehicle deliveries needed in Q4 to meet its 2023 goal. Analysts forecast a slight shortfall, with deliveries expected around 510,000 units, raising investor anxiety. Additionally, rising bond yields and broader market volatility contributed to the downward pressure on Tesla's stock. Despite strong sales in China, the overall sentiment remains cautious, with Tesla's stock rally showing signs of fatigue after a 70% increase over the past three months.
