The day trader’s ultimate objective is usually to trade expensive and volatile stocks on the NASDAQ and NYSE markets in increments of 1,000 shares or more, and profit from the small intra-day price movements. The day trader may possibly make many trades within a day, holding onto stocks for just a few minutes (or hours), and virtually never overnight. Day traders are short-term price speculators. They aren’t investors, and they’re not gamblers.
Day trading is not really investing. The day trader’s time frame of analysis is rather small: one day. Their only intention is to exploit the stock’s intra-day price swings or daily price volatility. Unlike stock investors, day traders tend not to seek long-term value appreciation.
Stock volatility is generally a rule of the market rather than an exception. The majority of stock prices move up or down in any given day due to a number of external factors. Even when the market is relatively calm, there are always stocks that are volatile. Day traders want to identify a stock with a trend and consequently go with that trend. “Trend is a friend” is a common motto amongst day traders. Day traders seek to pick up a somewhat small stock movement, 1/8 or more on that stock. If day traders are trading a sizable block of shares (that is, 1,000 shares per trade), then day traders will profit $125 from a 1/8 price movement. However, if a day trader obtained 1,000 shares and the trader ended up being completely wrong, which also occurs, then the day trader will lose $125 from a 1/8 price movement. Volatility can be a double-edged sword.
For expensive stocks that trade for $100 or more, a 1/8 or 12.5 cents movement is usually such a small relative price change that it happens constantly. Consequently there are plenty of day trading options. It’s not uncommon to see a day trader executing many, sometimes as many as 100, trades in one day. Conversely, an investor’s time frame is actually significantly longer. Investors search for a significantly larger price movement than 1/8 to earn the sought after rate of return. That usually takes time.
In short, day traders seek to extract an income from intra-day price volatility by trading the stock often, whereas the investors look for a long-term capital appreciation.
