Which Industry to Short Which Investors Would Prefer GARP Investing

Which Investors Utilize Stop-Loss Orders?

No matter what type of investor you are, you should know why you own a stock. A value investor's criteria will be different from that of a growth investor, which will be different still from an active trader. Any one strategy may work, but only if you stick to the strategy. This also means that if you are a hardcore buy-and-hold investor, your stop-loss orders are next to useless. The point here is to be confident in your strategy and carry through with your plan. Stop-loss orders can help you stay on track without clouding your judgment with emotion.
