Limit orders are a key concept in finance that refers to the instructions given by an investor to a broker to buy or sell a security at a specific price or better. These orders are different from market orders, which are executed immediately at the current market price. Limit orders allow investors to have more control over their trades and potentially get a better price for their securities. As a knowledgeable professor in finance, I encourage you to consider the benefits of using limit orders in your investment strategy.
