Tesla Surges to Market Activity Lead as Robotaxi and Energy Expansion Drive $36B Trading Volume

On August 11, 2025, Tesla (TSLA) surged 2.85% with a trading volume of $36.01 billion, ranking first in market activity. The rally followed CEO Elon Musk’s announcement that Tesla’s Robotaxi service in Austin would open to the public next month, marking a pivotal step in autonomous vehicle deployment. The company also applied to operate as a power supplier in the UK, signaling energy market expansion. Musk highlighted upcoming FSD V14 software improvements, emphasizing “dramatic gains” in autonomous capabilities.

Investor enthusiasm was further fueled by extended Model Y wait times, indicating strong demand amid the expiring $7,500 federal EV tax credit. While first-half EV sales declined year-over-year, progress in autonomous tech and energy diversification has shifted focus from near-term production challenges. Analysts note Tesla’s valuation remains elevated, trading 29.1% below its 52-week high despite a 65% annual gain.

A backtested strategy of purchasing the top 500 stocks by daily trading volume and holding for one day generated a 166.71% return from 2022 to present, outperforming the benchmark by 137.53%. This highlights liquidity concentration’s role in short-term momentum, particularly in volatile markets where high-volume stocks like Tesla can amplify price movements.
