Books provide a wealth of information and are inexpensive compared to the costs of classes, seminars, and educational DVDs sold across the web.

When you've been approved for margin stock trading, you're also eligible to short stock. Almost every successful stock trader has shorted stock at one time or another. When you short stock, you make money when the company's shares fall—or, even better yet, when they crash. The problem is that you can expose yourself to unlimited liability when you do this.

Wald says refiners are the best group within the energy sector, and Marathon Petroleum has significant long-term momentum following a breakout above $60 in late 2017. In addition to its positive momentum, Marathon recently raised its dividend by 15 percent and now yields about 2.1 percent. Even at its current payout, the stock’s relatively low 21 percent payout ratio suggests more hikes could be on the way in the near future. Marathon also recently diversified away from its Gulf-Coast-centric operations by acquiring Andeavor (ANDV) and its West Coast and Rocky Mountains assets for $23 billion.
If you trade stock regularly, you might find yourself accidentally violating the dreaded wash-sale rule. This means you've sold shares of stock and then bought the same or similar shares shortly thereafter. This can cost you huge tax penalties. With a little planning, you can avoid this fate and still enjoy trading stocks aggressively with a little planning.

Two well-respected services include Investors.com and Morningstar.

Momentum investing usually involves a strict set of rules based on technical indicators that dictate market entry and exit points for particular securities. Momentum investors sometimes use two longer-term moving averages, one a bit shorter than the other, for trading signals. Some use 50-day and 200-day moving averages, for example. The 50-day crossing above the 200-day creates a buy signal. A 50-day crossing back below the 200-day creates a sell signal. A few momentum investors prefer to use even longer-term moving averages for signaling purposes.
