Understanding Risk and Return: The Roller Coaster Ride of Investing

Investing money requires research and strategy, since the risks and rewards can be considerable. Before making the commitment, a would-be investor should understand the elements of an investment – from risk and return, to short-term notes and inflation. Read More

What’s the difference between investing your money and stashing it beneath your mattress? Rather than five $20 bills that become a little frayed and weathered over time in your bedroom, when invested, that same $100 might quickly grow to $150 – or it might lose value and dwindle to $75.

It is important to understand the key elements of an investment before digging out those $20 bills and putting them into stocks, bonds or some other means of potentially growing your money. Concepts to think about include risk, return, the effects of inflation on an investor’s return and what is involved in a so-called “risk-free” return, according to Mark McLennon, vice president of Investment Advisory Services with Northwestern Mutual, a financial security company based in Milwaukee, Wisc. “When people talk about risk in the stock market, some of them think about danger or uncertainty,” says McLennon. “But when it comes to investing, the risk can be quantified, or measured, based on historical trends.”

A quantifiable risk isn’t the same as a guarantee, since unanticipated events ranging from technological advances to a sudden shift in the economy can still throw a curveball into how your investment performs. Even so, risk measurement may be able to help an investor to plan his or her strategy, says McLennon.

More Risk, Greater Return — Usually

The holy grail of investing is return, or the profit that a person hopes to make from his investment. The ROI, or return on investment, is usually related to the degree of risk involved, and can be calculated by dividing the investor’s profit — the gain from the investment minus its cost — by the cost of the investment. The result is expressed as a percentage or a ratio. For example, someone who makes $25 on a $100 investment would have a 25% ROI.

“Typically, if there is more risk, an investor expects a larger return over time,” McLennon notes. “You can have different kinds of return, like growth in value or a rise in the price of a stock. Return can also refer to the interest or dividends associated with the investment.”

ROI was an important concept for Kunal Kochar, a 17-year-old senior at Neuqua Valley High School in Naperville, Ill., who was on a team that turned $100,000 of virtual investments into more than $171,640.60 in 14 weeks last year, taking first place in the national 2011 Securities Industry and Financial Markets Association (SIFMA) Foundation Stock Market Game.

The annual SIFMA competition lets students use the Internet and other research and news updates during a 14-week period to decide on their investments. “I’ve actually invested before, and my personal strategy is to buy and hold [the stocks I purchase],” Kochar says. “But the nature of the competition meant that we probably wouldn’t have achieved winning results without taking on a lot of risk.”

Kochar says the team “looked at a lot of things, including getting the greatest ROI in a short period of time.” Among other sources, they used Barron’s (financial magazine), Bloomberg (business and financial news) and analysts’ opinions to make their investment decisions. “At school, we’d sit at the computer during lunch to check our picks, and then we’d run right home after school to check closing prices.”

Before making their initial investments or switching to other stocks, the team considered issues like past performance, and technical factors like price-to-earnings ratios (a measure of the price paid for a share of stock relative to the annual net income or profit earned by the firm per share) and other ratios that can be used to compare companies’ stock prices for value.

Beware of Inflation

For cautious investors, putting their money into short-term notes guaranteed by the U.S., is considered to be just about risk-free, says McLennon. The tradeoff, of course, is a lower return. “Three-month treasury bills, for example, currently pay an annualized yield of about 8¢ to 10¢ on every $100 of face value. So people should consider both the risk-free return, and the premium, or rate they’re getting for taking on risk.”

Return can’t be considered as a stand-alone concept, he adds. Inflation, or the rise in general prices, can reduce the real rate of return. Inflation is a rise in prices in a given area over a period of time. For example, soda that costs $1.50 today in the U.S. was at one time priced at 5¢. This is an important consideration in investing. “If your return on investment doesn’t at least keep pace with inflation, you’re actually losing money,” McLennon notes. “So the real rate of return is the unadjusted ROI, less the rate of inflation.” For example, an investment that has a nominal, or unadjusted ROI of 4% during a time when inflation is 5%, would actually suffer a 1% loss.

“I was fairly familiar with risk-reward concepts [because] I’ve been tracking stocks since I was young,” says Brad Stimple, 18, a senior on the first-place Neuqua Valley High School stock market team. “It was a real roller-coaster ride. We started off poorly, with a 20% portfolio loss at one point. But we polished our strategy and, in the end, it worked out. Some of the lessons we learned in the stock market competition can also be applied to our personal lives. In both, you have to find your own balance of risks and rewards. It’s something to think about.”

  1. I’ll never forget the conversation that I overheard on my first day as an intern at Anand Rathi investments, ” I’m looking for an investment that guarantees a 12-15% annual return with no risk. I should be able to encash it whenever without any exit fee.”

    Little did I realize that this is the daily dilemma that investment specialists face. Any investment decision involves two sub decisions, the expected return on the investment and the risk undertaken to achieve the return. In other words, increasing the probability of obtaining the desired outcome is reducing the risk.

    My toying around with stocks had made me realize that the higher the return, the greater is the risk. Earning returns that beat inflation is mandatory. Inflation is a rise in prices in a given area over a period of time and hence it can reduce the real rate of return. As our goal was to outperform the inflation rate, additional risk needed to be taken.

    Being a sports fanatic, I have unconsciously dabbed in statistics and sports analytics all my life. Statistics silently drives all major decisions in my life. Subconsciously I use it to predict outcomes for games and rate my favorite players.

    As it was important to define, measure, and manage risk, I started working on a simple mathematical model to calculate the risk, using standard deviation. This model could be generalized and used across stock markets in the world (Hang Seng, Nikkei, NASDAQ etcetera) and financial products for different time intervals [5-years, 7-years and so on and so forth.]. The goal of this model was to calculate risk mathematically based on past performance and the to determine the probability of achieving the mean outcome and we calculated an 84% probability of getting a return over 7.5%. Over the summer, I completed a class in Artificial Intelligence (AI) in Bangalore, conducted by Stanford University. Now I plan to combine what I have learned in AI to enhance my model using Real-Time Machine Learning to check if the market conditions (news, GDP etcetera) are favorable or not.

    Just like this model tries to minimize the crests and troughs of investing, we must maintain a stable stature in life without letting the rollercoaster rule us!

  2. Quantifiable Risk: A quantifiable risk is a risk that can be measured and expressed in numerical terms. It is a risk that can be analyzed, estimated, and assigned a specific probability or impact.

    Threat to Rate of Return: Inflation is a key factor that can threaten the rate of return on investments. If the rate of return on investments does not outpace the rate of inflation, the real value of the investment can erode over time.

  3. I am a risk averse person, and I prefer to save money rather than spend it; I don’t like investing because I’m afraid of losing money

    • It’s all about balance. No good investor will ever invest their money into one place and will even limit the money invested as a whole. Diversification and pre-planning these investments you have your eye on can help you get started. I myself now apply this whenever I am allowed to buy some shares by my father. I wish you good luck.

    A quantifiable risk assigns a numerical number to extant risks. have invested in stocks and luckily it turned out well.
