Understanding The Relationship Between Risk and Reward In Investments
Definition of risk/reward tradeoff: Direct relationship between possible risk and possible reward which holds for a particular situation. To realize greater reward. Most economists and investment advisers use what is called the risk pyramid to demonstrate the relationship between risk and reward. Although renderings of. Risk-return tradeoff is a specific trading principle related to the inverse relationship between investment risk and investment return. an essential role in determining a portfolio with the appropriate levels of risk and reward.
Risk Fallacy Number 3: That risk can be measured. Most work on risk assumes that historic nominal before adjusting for inflation volatility of the stock market price or the historic correlation beta of an individual stock with the market are good measures of risk.Risk and Reward Prof Simply Simple & Suppandi Hindi
Beta may capture the market related risk and under CAPM that is the only risk that matters since all other risk can and should be diversified away. But studies have shown that beta varies over time, therefore it is not clear that beta can be actually measured. And calculations of beta vary dramatically depending if one works with monthly, daily, weekly or annual returns. And if one believes that diversifiable risks are also relevant then it is clear that those cannot be so easily measured.
How can you measure the chance that completely random events will occur? In addition some investors are not so concerned about volatility but are much more concerned about the risk that their long term wealth will be below an acceptable level.
Short term volatility does not address very well the risk of long term purchasing power. For example treasury bills are not risky in the short term but putting all funds into Treasury bills would cause a large risk of insufficient long term purchasing power, as the returns barely keep up with inflation.

My belief is that at best we can get a rough qualitative sense of the risk but we cannot precisely measure it. I also believe that their is too much focus on short term volatility and not enough focus on the risk of long term real after inflation wealth risk.
Risk Fallacy Number 4: Well, they might all be market returns but they are not equivalent in any sense. And there is some small chance that even over many years the risk free rate will actually turn out to beat the market return. A mythical average investor might be indifferent to the two positions along the SML. I may choose the safe route and expect a lower return. You may choose to take a maximum amount of risk and its expected far superior return.
There is nothing equivalent about this. Neither of us would be willing to trade places. You might have been willing to take on all that risk for a much lower risk premium than the market is currently paying.
I might not have been willing to take on the risk even if the market risk premium was significantly larger. The range width is larger, and follows the influence of increasing risk premium required as the maturity of that debt grows longer.
Nevertheless, because it is debt of good government the highest end of the range is still comparatively low compared to the ranges of other investment types discussed below. Also, if the government in question is not at the highest jurisdiction i.
Short-term loans to blue-chip corporations[ edit ] Following the lowest-risk investments are short-dated bills of exchange from major blue-chip corporations with the highest credit ratings.
The further away from perfect the credit rating, the higher up the risk-return spectrum that particular investment will be. Mid- and long-term loans to blue-chip corporations[ edit ] Overlapping the range for short-term debt is the longer term debt from those same well-rated corporations. These are higher up the range because the maturity has increased. The overlap occurs of the mid-term debt of the best rated corporations with the short-term debt of the nearly perfectly, but not perfectly rated corporations.
In this arena, the debts are called investment grade by the rating agencies.
Risk versus Reward
The lower the credit rating, the higher the yield and thus the expected return. Rental property[ edit ] A commercial property that the investor rents out is comparable in risk or return to a low-investment grade.
Industrial property has higher risk and returns, followed by residential with the possible exception of the investor's own home.

- The equity premium
High-yield debt[ edit ] After the returns upon all classes of investment-grade debt come the returns on speculative-grade high-yield debt also known derisively as junk bonds. These may come from mid and low rated corporations, and less politically stable governments. Equity[ edit ] Equity returns are the profits earned by businesses after interest and tax.
Even the equity returns on the highest rated corporations are notably risky. Small-cap stocks are generally riskier than large-cap ; companies that primarily service governments, or provide basic consumer goods such as food or utilities, tend to be less volatile than those in other industries.
Note that since stocks tend to rise when corporate bonds fall and vice versa, a portfolio containing a small percentage of stocks can be less risky than one containing only debts. Options and futures[ edit ] Option and futures contracts often provide leverage on underlying stocks, bonds or commodities; this increases the returns but also the risks. Note that in some cases, derivatives can be used to hedgedecreasing the overall risk of the portfolio due to negative correlation with other investments.
For example, the more risky the investment the more time and effort is usually required to obtain information about it and monitor its progress. For another, the importance of a loss of X amount of value is greater than the importance of a gain of X amount of value, so a riskier investment will attract a higher risk premium even if the forecast return is the same as upon a less risky investment. Risk is therefore something that must be compensated for, and the more risk the more compensation required.
If an investment had a high return with low risk, eventually everyone would want to invest there. That action would drive down the actual rate of return achieved, until it reached the rate of return the market deems commensurate with the level of risk. Similarly, if an investment had a low return with high risk, all the present investors would want to leave that investment, which would then increase the actual return until again it reached the rate of return the market deems commensurate with the level of risk.
That part of total returns which sets this appropriate level is called the risk premium.
