Day traders are attuned to events that cause short-term market moves. Trading the news is a popular technique. Scheduled announcements such as economic statistics, corporate earnings or interest rates are subject to market expectations and market psychology. Markets react when those expectations are not met or are exceeded, usually with sudden, significant moves, which can benefit day traders.
The goal of swing trading is to capture a chunk of a potential price move. While some traders seek out volatile stocks with lots of movement, others may prefer more sedate stocks. In either case, swing trading is the process of identifying where an asset's price is likely to move next, entering a position, and then capturing a chunk of the profit from that move.
Individual traders often manage other people's money or simply trade with their own. Few of them have access to a trading desk, but they often have strong ties to a brokerage (due to the large amounts they spend on commissions) and access to other resources. However, the limited scope of these resources prevents them from competing directly with institutional day traders. Instead, they are forced to take more risks. Individual traders typically day trade using technical analysis and swing trades—combined with some leverage—to generate adequate profits on such small price movements in highly liquid stocks.
The next important step in facilitating day trading was the founding in 1971 of NASDAQ—a virtual stock exchange on which orders were transmitted electronically. Moving from paper share certificates and written share registers to "dematerialized" shares, traders used computerized trading and registration that required not only extensive changes to legislation but also the development of the necessary technology: online and real time systems rather than batch; electronic communications rather than the postal service, telex or the physical shipment of computer tapes, and the development of secure cryptographic algorithms.
The profit potential of day trading is perhaps one of the most debated and misunderstood topics on Wall Street. Internet day trading scams have lured amateurs by promising enormous returns in a short period. The idea that this kind of trading is a get-rich-quick scheme persists. Some people day trade without sufficient knowledge. But there are day traders who make a successful living despite—or perhaps because of—the risks.
Retail investors are prone to psychological biases that make day trading difficult. They tend to sell winners too early and hold losers too long, what some call “picking the flowers and watering the weeds.” That’s easy to do when you get a shot of adrenaline for closing out a profitable trade. Investors engage in myopic loss aversion, which renders them too afraid to buy when a stock declines because they fear it might fall further.
