Investing in the stock market has always been an effective way to build wealth. In today’s low interest-rate, it has become a necessity.

Since the Great Recession in 2008, the Federal Reserve has kept short-term interest rates—called the “federal funds rate”—at or near zero. That means the traditional ways of saving your money and watching it accrue—certificates of deposit, money-market accounts, Treasury bonds—are no longer viable. Investing in the stock market is one of the few viable ways to have your money work for you these days.

Of course, stock market investing comes with more risk than a safe, low-yield savings account. Inevitably, not all of your investments will be winners.

In investing, no one really knows for sure what’s going to happen. Over time, however, stocks tend to rise. History tells us this. Since 1928, the average annual return in the S&P 500, the benchmark U.S. stock index, is 11.5%. So historically, the average stock rises 11.5% per year.

Successful investing is largely dependent on market timing. You can’t just buy any stock and assume it will turn a profit, much less return 11.5%. You have to buy the right stocks at the right time.

For example, if you bought stocks in 2011 and sold them at the end of the year, you probably didn’t fare so well. The S&P 500 was essentially flat that year. However, if you bought stocks at the beginning of 2012 and held on to them through 2014, you probably made a lot of money. The average annual return from 2012 to 2014 was 20.5%.

But, of course, your return would have depended on what stocks you actually bought. Take Apple (AAPL), for example. The largest and most recognizable technology company in the world has been perhaps the single best-performing stock of the past decade. But Apple had a rough stretch from September 2012 to June 2013, falling more than 43% at a time when most stocks were reaching record heights. The rising tide of the market doesn’t necessarily lift all boats—even the biggest boat.

That kind of unpredictability scares some people away from investing in the stock market. The track record over time should be enough to convince you otherwise.

The stock market is a vast and ever-evolving place, and there are many ways to approach stock market investing.

Want to invest in safe companies that offer a steady stream of income? You’re probably a dividend investor.

Are you willing to take on a bit more risk to go after bigger, faster rewards? Growth investing is likely for you.

Value investing is for investors who like to bargain shop.

Options trading is for those who like to invest based on statistical probabilities. And so on.
