Trading, on the other hand, involves the more frequent buying and selling of stock, commodities, currency pairs or other instruments, with the goal of generating returns that outperform buy-and-hold investing. While investors may be content with a 10 to 15% annual return, traders might seek a 10% return each month. Trading profits are generated through buying at a lower price and selling at a higher price within a relatively short period of time. The reverse is also true: trading profits are made by selling at a higher price and buying to cover at a lower price (known as "selling short") to profit in falling markets. Where buy-and-hold investors wait out less profitable positions, traders must make profits (or take losses) within a specified period of time, and often use a protective stop loss order to automatically close out losing positions at a predetermined price level. Traders often employ technical analysis tools, such as moving averages and stochastic oscillators, to find high-probability trading setups.

A trader's "style" refers to the timeframe or holding period in which stocks, commodities or other trading instruments are bought and sold. Traders generally fall into one of four categories:

Position Trader – positions are held from months to years
Swing Trader – positions are held from days to weeks
Day Trader – positions are held throughout the day only with no overnight positions
Scalp Trader – positions are held for seconds to minutes with no overnight positions

Traders often choose their trading style based on factors including: account size, amount of time that can be dedicated to trading, level of trading experience, personality and risk tolerance. Both investors and traders seek profits through market participation. In general, investors seek larger returns over an extended period through buying and holding. Traders, by contrast, take advantage of both rising and falling markets to enter and exit positions over a shorter timeframe, taking smaller, more frequent profits.
