Definitions for "Day Traders"
online investors who buy and sell a stock on the same day hoping to make profit from any small increments in price.
The ultimate speculators are day traders, a phenomenon created by the internet/technology boom, who buy (or, less commonly, sell) shares in the morning in the hope of exiting at a profit within a day. This is an approach which can only work, if at all, in a one-way bull or bear market in which prices rise or fall with great regularity.
Speculators who take positions in futures or options contracts and liquidate them before the close of the same trading day.
