The potential cancellation of EV subsidies to finance a tax cut plan is something that could have significant implications for the electric vehicle market. If these subsidies are removed, it could increase the cost of EVs, affecting their affordability and demand. As a result, this could also create volatility for companies like Tesla, especially given that its stock is already relatively high.

I wouldn't be surprised if Tesla's stock dips below $300, considering its current valuation and the inherent volatility of its stock price. Tesla's shares have shown to be unpredictable in the past, and in my opinion, the stock is currently overvalued, which makes it less appealing for new investors.

While Tesla is undoubtedly an innovative and successful company with a strong presence in the EV market, I believe there are better investment opportunities elsewhere that offer more stability and value. That being said, Tesla’s technological advancements and market leadership do make it a fascinating company to watch in the long run.
