Investing and trading are financial activities that involve the buying and selling of assets with the goal of generating a profit either in the long or short term.

Investing generally refers to a longer-term approach, where you purchase assets such as stocks, bonds, and real estate with the expectation of holding them for a period of time and benefiting from the appreciation in value over time or the payment of interest or dividends.

Trading, on the other hand, generally involves a shorter-term approach, where you buy and sell assets more frequently, attempting to profit from short-term price movements.

Both investing and trading can be done in various markets, including the stock market, bond market, commodities market, and foreign exchange market.
