    Most traders have heard of options, but new really understand them. The old adage that "a little knowledge is a dangerous thing" applies, of course, but it makes sense to at least have a basic knowledge about options and how they work.

    These contracts are intangible and can work as high-risk speculative moves or, on the opposite end, as practical strategic tools for managing your portfolio and even reducing risk. But before jumping in to an options trade, you need to master the basics and, at the very least, understand the risks first.

    An option is the right, but not the obligation, to trade shares of stock. The cost of the option is only a fraction of owning shares, so buying options enables you to control shares for a very low risk. Every option controls 100 shares of stock, and there are dozens of possible strategies. This makes options trading attractive, potentially profitable, complex, and dangerous.

    A call is the right to buy 100 shares of a specified stock by or before a specified date and at a fixed price. A put is the opposite, the right to sell 100 shares. If you buy a call, you can either sell or exercise the contract before its expiration date. For example, if you buy a call granting you to right to buy 100 shares at $30 per share by or before February (a Feb 30 call), you may sell that call if the stock price moves higher, and make a profit from the higher value of the call. Or if you decide to exercise, you buy 100 shares. For example, if you own a Feb 30 call and the underlying stock price rises to $38 per share, by exercising the call, you buy 100 shares at the strike price of $30.

    The opposite example is buying a put. You do this if you think the stock price may fall. For each point the price of the underlying stock falls below the fixed strike price, the put will gain one point in value. For example, if you buy a March 55 put when the underlying stock is at $57 per share, you are speculating that the stock price will fall before the put's March expiration. If the stock does indeed fall to $48 per share, you can do one of two things. You can sell the put and take a profit; or if you already own 100 shares, you can exercise the put and sell those shares for $55 per share, seven points higher than their current market value.

    There is much more, of course. The value of an option, called its premium, changes for many reasons beyond the movement of the stock. Time plays a role, and the farther away from expiration, the higher the time value will be. However, time value declines as expiration approaches, a big problem if you own the option. Volatility also affects prices of the option.

    Options trading is intricate and complex. Novices can get into it, but only with study and practice. The best way to practice without risk is to paper trade (trading a virtual portfolio without putting any real money at risk) as a means for learning how options markets really work. One of the best free paper trading sites is offered by the Chicago Board Options Exchange (NASDAQ:CBOE) at cboe.com, at the link "tools" and then to "virtual trade."

    To gain more perspective on insights to trading observations and specific strategies, I hope you will join me at ThomsettOptions.com where I publish many additional articles. I also enter a regular series of daily trades and updates. For new trades, I usually include a stock chart marked up with reversal and confirmation, and provide detailed explanations of my rationale. Link to the site at ThomsettOptions.com to learn more. You can take part in discussions among members on the site at the Members Forum.

    I also offer a twice-monthly newsletter subscription if you are interested in a periodic update of news and information and a summary of performance in the virtual portfolio that I manage. Join at Weekly Newsletter I look forward to having you as a subscriber.
