The company's share price has seen some big swings in 2025, and is down roughly 21% year to date with today's pop. </p> <h2>Is Tesla stock a buy right now?</h2> <p>Tesla launched robotaxi operations in Austin, Texas last month, and the rollout of the service in San Francisco is happening quicker than previously anticipated. While that's a bullish development for the company, challenges facing the core auto business still make the stock a risky buy right now.</p>  <p>Tesla's automotive revenue sank 16% year over year to land at $16.7 billion in the second quarter, and CEO Elon Musk said that the company could face a few quarters of relatively weak performance due to the impact of tariffs and the expiration of subsidies for the electric vehicle (EV) market. Despite big declines for its sales and earnings, the EV company is still valued at roughly 11 times this year's expected sales and 185 times expected earnings. While Tesla's robotaxi and robotics initiatives could potentially start being meaningful sales contributors within the next year, challenges facing the core auto business suggest that investors may be able to wait for a better buy-in point.</p>                                                                            </div>

<p>Tesla's stock surged 4.6% today, driven by news of its robotaxi service launching in San Francisco this weekend. Despite this gain, the stock is down 21% year-to-date following disappointing Q2 results and ongoing challenges in the automotive sector. CEO Elon Musk indicated potential weak performance ahead due to tariffs and subsidy expirations. While the robotaxi initiative is promising, analysts suggest that the core auto business challenges make Tesla a risky buy at this time.</p>
