Where to learn the jargon. Stocks come with their own language. There are things like "limit orders" that dictate buying at a certain price or "trading on margin" which is essentially borrowing money to purchase stocks. Jeff Reeves, executive editor of InvestorPlace, a resource for individual investors, says people shouldn't worry too much about the terms when they are starting out. Rather than try complicated transactions, new investors are best served by simply buying securities at market price. As people get comfortable with the basics, they can then branch out into more advanced trading scenarios.
The most important thing you can do is get an investing education first. Learn the basics of the stock market and if there is something that you don’t quite understand, ask. That’s the secret to successful investing for beginners. A good place to start is by reading Rule #1. It gives a great foundation to investing principles used by Warren Buffett and other great investors.
Also similar to a bank account, once your online brokerage account is open, the brokerage will ask you to "fund" it. You can do this in any of several ways -- for example, by mailing a check or making an electronic deposit directly from your bank. If you happen to sign up with a brokerage that has a physical office nearby, you could even walk in and hand someone a duffel bag full of cash.
This is where the fun begins, but you need to think things through carefully before you take the plunge. Firstly, you have to take a look at your personal finances and see if this is the right decision for you. Do you have savings set aside that you want to start earning money from? Are you in a comfortable financial position that doesn’t rely on the success of your stock marketing investments? If you want to invest in stocks purely as a source of primary income, then you’re going about things in the wrong way. This isn’t the article for you, this is about investing in stocks for beginners that are already financially stable and don’t depend on their investments.
Dividend discount model: the value of a stock is the present value of all its future dividends. Thus, the value of a stock = dividend per share divided by the difference between the discount rate and the dividend growth rate.  For example, suppose Company A pays an annual dividend of $1 per share, which is expected to grow at 7% per year. If your personal cost of capital (discount rate) is 12%, Company A stock is worth $1/(.12-.07) = $20 per share.
Since stock prices can be volatile, it is unwise to invest too heavily in any one company or sector (such as energy, technology, finance, etc.). Diversify to minimize risk, and adjust your asset allocation periodically to reflect either changes in the stock or changes in your needs (this is known as rebalancing your portfolio). A rough rule of thumb is to invest your age in bonds or more conservative investments, and the rest in stocks (at age 25, keep 75% of your investments in stocks). Even though stocks typically shine over the long haul, they can be quite risky over the short run. That is why savvy investors distribute some of their capital into other asset classes such as bonds, real estate and money markets.
These extra fees are another big cost to investors, but they aren’t deducted from your account balance. Instead, these fees show up in the price on the ticker tape. That’s why many high-priced mutual funds’ and ETFs’ value per share doesn’t seem to change over time — any growth is offset by fees. Also watch out for mutual funds that charge a front- or back-end load for each purchase or sale. These usually range from 0.5% to 1% and can add up quickly.
