Chapter 4 Risk Management
February 28th, 2009Playing a round of golf can be like investing in the stock market. One bad hole can ruin the round, while one bad investment can spoil the market. Ross Jardine in his book Bear Market Game Plan, Strategies for Success in Choppy Markets tells how you can take steps to get that bad investment out of your game.
- Stop loss order. A stop loss order will instruct your stock broker to automatically sell a stock when it drops to a certain price. This is important to have as it will limit the loss you will suffer on any one trade. Another important aspect of a stop loss order is that it will help prevent you from playing the stock market with your emotions. You should determine the stop loss order at the time of your purchase.
- Deciding on a stop loss. Jardine says that you should set your stop at 10 to 20% of the purchase price. If you buy the stock at $20 per share, a 20% stop would issue the order when the stock drops to $16 per share. Some investors who don’t like much risk will put the stock loss order at less than 10%. If you are trading in the options market the stop loss should be in the 30 to 50% range. Remember that you will almost always have a better chance of earning a loss back on your next trade than sticking too long with a stock.
- Choosing your stop. Remember the moving averages we discussed earlier. Make sure you use that research to help determine where to put your stop. You also need to be aware of support and resistance. Support is the point where buyers tend to jump in and offset any selling pressure. Look at the history of the stock and set up your stop just below the support level. Make sure you are following trends for the stock, the market and the segment of the market you are trading in.
- Stop order versus stop limit. Make sure you know the difference between a stop order and a stop limit. Some trading websites give you the option, Jardine says you should never go with a stop limit. The difference is simple to understand. Using the example from above, if the purchase price is $20 a share and you put the order at $16 a share your broker will automatically sell the stock when it hits $16. Since you can’t sell instantly, the price could be a little less than $16 or a little more. The point will be the stock will be sold and you are protected. With a stop limit, it will have to sell at $16 a share. Therefore if the price continues to drop it will not sell because it hasn’t returned to $16. To get out, you will have to over ride the stop limit and you could end up selling at a much lower amount than you want.
There are a couple of other things to consider with a stop order. Make sure you understand how your broker handles stop orders; some will automatically expire after a certain date. Don’t lower a stop loss from your original stop price. Trade with knowledge not with emotion.
