Portfolio Investment

What is Portfolio Investment?

Portfolio investments are investments made in a group of assets (equity, debt, mutual funds, derivatives, or even bitcoins) instead of a single asset with the objective of earning returns is commensurate with the risk profile of the investor. Portfolio investments might vary from a small segment of one industry to a wide-ranging – entire market.

Types of Portfolio Investment

An investment gives returns in proportion to its risk factor. If one invests in highly risky assets like bitcoin, they can either get absurdly high returns or go to zero. But if one invests in treasury bonds, the risk factor is almost zero, but the returns are also very low. And each financial investor will have their own risk profile, which is tailored to their specific investments.

But the investments available in the market are not tailored to such needs. Hence each investor will have a specific requirement that can be maintained using a portfolio. The different types of portfolio investment are as follows:

The thought that one can attain high returns with low risk is a difficult one to perceive. The free market dynamics call it arbitrage – when two similar risk profiles pay off at different scales, one of them has a benefit over the others. Such a difference slows the investors to pounce on the opportunity and neutralize the benefit of difference in returns for similar risk portfolios. This is called as law of one price, and such a law of one price does not allow the same risk assets to have the same price. One should keep this in mind while preparing a portfolio – any returns more than that for the specific risk rate will not stand the test of time.

Example of Portfolio Investment – Returns & Risks

Let us take an example scenario to see how portfolio investment returns and risks are calculated and represented.

For this, we will imagine a treasury bond that yields a return of 2% per annum. Treasury bonds are considered risk-free because they are backed by the US govt. So, the net variability/risk/variance in the returns will be zero. This means that a hundred percent of the time, the returns will be only 2% per annum.

Let us assume a stock with an average return of 10% and a variance of 2%. This means that if the returns are normally distributedNormally DistributedNormal Distribution is a bell-shaped frequency distribution curve which helps describe all the possible values a random variable can take within a given range with most of the distribution area is in the middle and few are in the tails, at the extremes. This distribution has two key parameters: the mean (µ) and the standard deviation (σ) which plays a key role in assets return calculation and in risk management strategy.read more, the net returns lie between 8% and 12% for 68% of the time.

If an investor builds a portfolio by investing 50% of his money in bonds and the rest in stock, then he can have an average return of about 6%. This is higher than the mean returns of bonds and lower than the mean returns of a stock. Precisely the reason why portfolios exist. If the investor wants to increase his risk, he can increase the share of stocks, and if he wants to decrease his risk, he can increase the share of his bondsBondsA bond is financial instrument that denotes the debt owed by the issuer to the bondholder. Issuer is liable to pay the coupon (an interest) on the same. These are also negotiable and the interest can be paid monthly, quarterly, half-yearly or even annually whichever is agreed mutually.read more.

Disadvantages of Portfolio Investment

The following are the disadvantages of portfolio investments.

  • One of the important reasons for proper stock marketStock MarketStock Market works on the basic principle of matching supply and demand through an auction process where investors are willing to pay a certain amount for an asset, and they are willing to sell off something they have at a specific price.read more functioning is the information flow. Information flow is the theory where, because of the money involved, the decision making during the stock price movement helps the company in gauging the conditions of the market and of the general public. If the stock price moves after a certain decision, it helps the company in deciding whether the decision made is a good decision or not. However, with portfolio investment, the movement of such stock prices becomes more uncertain as the risk is gauged as a whole, and hence the flow of information is uncertain.
  • If proper research is not done, and a proper risk profile is not calculated, the portfolio will not yield optimum returns.
  • In order to calculate what the returns have to be for a certain amount of risk, the person has to analyze multiple stocks and form a portfolio. Though there are companies available that analyze these sorts of portfolios and provide them, that still does not benefit the user to a complete extent.
  • Financial knowledge is mandatory for people who are trying to invest in using a portfolio instead of individual stocks. The relations between individual stocks, between stocks and markets, is a difficult thing to analyze.

Conclusion

Like every investment in finance, the decision to invest in a portfolio or not is a choice. But the decision many people make over here shows the obvious importance of portfolios in modern investing. They provide a method of customization, exactly where it is necessary.
