Share prices are typically found on financial websites, stock exchanges' official platforms, or through brokerage firms' online platforms. You can check the share price of a company by looking it up on popular financial websites like Yahoo Finance, Google Finance, or Bloomberg. Additionally, if you have an account with a brokerage firm, you can log in to your account and find the share prices there. Stock exchange websites, such as the New York Stock Exchange (NYSE), NASDAQ, or the London Stock Exchange (LSE), also provide real-time or end-of-day share prices.
