This strategy is mostly only done by day traders. It requires that you have access to one to several real-time news sources and can make split second decisions. News and rumors can provide large amounts of volatility and high emotion creating great opportunities if traded properly. The biggest challenge of trading this strategy is anticipating the market’s reaction to the news and how it effects the price of the stock. Click here for more information on trading news and rumors.
Assess how much capital you're willing to risk on each trade. Many successful day traders risk less than 1% to 2% of their account per trade. If you have a $40,000 trading account and are willing to risk 0.5% of your capital on each trade, your maximum loss per trade is $200 (0.005 x $40,000). Set aside a surplus amount of funds you can trade with and you're prepared to lose. Remember, it may or may not happen.
