Bottom line

While it’s possible to turn a profit investing in security stocks, keep in mind that — like any investment — security stocks are not immune to risk. These stocks are subject to fluctuating conditions — both in the market and in the online and physical security industry, so carefully vet your picks before you invest. And if you’re new to investing, or if it’s been awhile since you’ve taken a critical look at your investing accounts, compare brokers to make sure you’re getting the best features in your trading account.
