Which share will double in 3 years?

It is not possible to accurately predict which stock will double in value within a specific time frame, as the performance of a stock can be influenced by a variety of factors such as the company's industry, market conditions, and management. The stock market can be volatile, and the value of individual stocks and the overall market can go up or down. It is important to carefully consider your investment decisions and be aware of the risks involved in investing in the stock market. It is always a good idea to diversify your portfolio and invest in a mix of assets to spread risk and manage volatility. It is also important to remember that past performance is not necessarily indicative of future performance.
