What should I be aware of as a young investor?
Don't start by investing in a few individual companies. This is risky. Want an example? I'm thinking of a big company, say $120 billion or so, a household name, and good consistent dividends to boot. They were doing fairly well, and were generally busy trying to convince people that they were looking to the future with new environmentally friendly technologies. Then... they went and spilled a bunch of oil into the Gulf of Mexico. Yes, it wasn't a pretty picture if BP was one of five companies in your portfolio that day. Things would look a lot better if they were one of 500 or 5000 companies, though. So. First, aim for diversification via mutual funds or ETFs. (I personally think you should probably start with the mutual funds: you avoid trading fees, for one thing. It's also easier to fit medium-sized dollar amounts into funds than into ETFs, even if you do get fee-free ETF trading. ETFs can get you better expense ratios, but the less money you have invested the less important that is.) Once you have a decent-sized portfolio - tens of thousands of dollars or so - then you can begin to consider holding stocks of individual companies. Take note of fees, including trading fees / commissions. If you buy $2000 worth of stock and pay a $20 commission you're already down 1%. If you're holding a mutual fund or ETF, look at the expense ratio. The annualized real return on the stock market is about 4%. (A real return is after adjusting for inflation.) If your fee is 1%, that's about a quarter of your earnings, which is huge. And while it's easy for a mutual fund to outperform the market by 1% from time to time, it's really really hard to do it consistently. Once you're looking at individual companies, you should do a lot of obnoxious boring stupid research and don't just buy the stock on the strength of its brand name. You'll be interested in a couple of metrics. The main one is probably the P/E ratio (price/earnings). If you take the inverse of this, you'll get the rate at which your investment is making you money (e.g. a P/E of 20 is 5%, a P/E of 10 is 10%). All else being equal, a lower P/E is a good thing: it means that you're buying the company's income really cheap. However, all else is seldom equal: if a stock is going for really cheap, it's usually because investors don't think that it's got much of a future. Earnings are not always consistent. There are a lot of other measures, like beta (correlation to the market overall: riskier volatile stocks have higher numbers), gross margins, price to unleveraged free cash flow, and stuff like that. Again, do the boring research, otherwise you're just playing games with your money.
