Buying Tesla stock today means becoming a partial owner of the company, and the number of shares bought will determine how much ownership one has. However, there is no guarantee that buying Tesla stock today will result in a profit, and the stock price is volatile, meaning it can go up or down significantly in a short period of time. Before buying Tesla stock, it is important to do research and understand the risks involved, as well as consider investment goals and risk tolerance. As of September 29, 2023, Tesla stock is around 12% below its official entry point and is not a buy right now. However, some analysts have given Tesla stock a "Strong Buy" rating with a mean target price of $6.62, indicating an upside potential of about 25% from the current price. It is important to note that the stock market is constantly changing, and the decision to buy Tesla stock should be based on individual research and analysis of the current market conditions.
