In broad terms, risk involves exposure to some type of danger and the possibility of loss or injury – whether that’s to your physical health, social status or something else. People face numerous risks every day, doing things like driving to work and texting while walking – or worse, while driving (please don’t). There are also risks that stem from things you aren’t doing (but should) – like getting enough sleep, exercising regularly and eating a healthy diet.  

Of course, some activities are riskier than others. Certain adventure sports, for example – such as free climbing, BASE jumping, big wave surfing and bull riding (the “most dangerous eight seconds in sport”) – expose participants to higher-than-normal levels of risk. For many adventure enthusiasts, that’s the whole point. Still – no matter what risks you face – there are usually ways to lower the possibility of loss or injury, whether that’s learning to hold your breath as a big wave surfer or wearing a seatbelt as a morning commuter.

Reality vs. Expectations

In the investing world, risk refers to the chance that an investment’s actual return will differ from the expected return – the possibility that an investment won’t do as well as you’d like, or that you’ll end up losing money. The good news: Like other dangers we face, it’s possible to manage investing risks – by learning what they are and by diversifying your portfolio. That way, one bad investment can’t do serious damage to your overall financial health. (See also: Common Risks That Can Ruin Your Retirement.)

To help you get started, this tutorial introduces risk and provides a good foundation for understanding the relationship between return and risk, as well as the importance of diversification. (For related reading, see: Calculating Risk and Reward.)
