Overtrading refers to excessive buying and selling of financial assets within a short period, often driven by emotions like greed or fear. It can lead to increased transaction costs, higher taxes, and diminished returns due to frequent trades. Overtrading often results from a lack of discipline, failure to adhere to a trading plan, or seeking instant gratification. It can also lead to increased exposure to market volatility and higher risk of losses. Effective risk management strategies and sticking to a well-defined trading strategy can help mitigate the negative impacts of overtrading.
