Step-by-step explanation:
Investors who buy and sell stock on the same day are called day traders.
Day traders aim to profit from short-term price fluctuations in the stock market. They typically make multiple trades within a single day, taking advantage of small price movements. Day trading requires active monitoring of the stock market and knowledge of technical analysis.
Some day traders use strategies such as scalping, where they buy and sell large quantities of stock within minutes or seconds, while others focus on momentum trading or breakout trading.
