Portfolio's Investment Returns

Aug 29, 2022 By Triston Martin

Investors need to look at the expected returns of each investment; they have to be aware of factors like the risk of a downturn in markets, market conditions, and the time required to allow each asset to achieve its gains. Also, they have to consider the possibility of opportunity costs incurred by an investment with a high chance of earning returns that could be less appealing if that same amount of money could be used more profitably in other investment options.

Calculating Returns for a Single Investment

Following that is to learn to determine ROI for every asset. This metric can quantify how well an asset puts your money to put to. The return on investment of a single purchase is calculated as a result of dividing the net increase from the investment by the asset's initial cost. The price of an asset does not comprise just the purchase price as well as any charges for management, commissions, or other costs associated with the purchase. The sum of these amounts is the value increase as a percentage of the asset's value. While it's not an exact technique, it indicates how well the investment's performance is compared to the entire portfolio.

Calculating Returns for an Entire Portfolio

As we've mentioned, there are risks associated with investing, which means you're unable to know how much you'll earn or whether you'll actually earn any money. There are market forces that could affect an investment's performance. The investment includes the effects of political and economic forces such as market sentiment and the actions of corporate entities. But that doesn't mean that you should not calculate the numbers.

Calculating the return on individual investments is exhausting, particularly when you've got your funds split across multiple investment vehicles managed by different organizations and firms. First, you need to record each asset on an excel spreadsheet, with the calculated ROI and dividends, as well as management fees, cash flows, and other data pertinent to the costs or the returns of these assets. It is important to be aware of these:

  • Cost total of an investment, including commissions and fees.
  • The historical returns for every investment
  • The portfolio's weight for each investment is expressed as a percentage of the portfolio's total value.

Other Factors

Although the above method is a well-known and simple method for estimating the returns of portfolios, it doesn't take into account other important factors, like the period of time for each asset or the additional dividends from bond or stock dividends. To be able to take into account these variables in your calculations, you'll need to think about a few things. One is to identify the time frame within which you'd like to calculate returns: daily, weekly or monthly, quarterly, or annually. Additionally, you must identify the net asset value of every portfolio position for the specified time period and note the cash flow in the event they are applicable.

Holding Period Return

After you have defined your time frames and added the portfolio NAV, you can begin formulating your calculations. The method to determine a base return is calculating the return on holding. The yield or return can be used to evaluate the returns of investments held over time. It determines the percentage change between a period to the time of the overall portfolio NAV and also the earnings from dividends and interest. It's the total amount of return earned from holding the portfolio of assets or one asset for a particular time period.

Adjusting for Cash Flows

You'll need to adjust the timing and quantity of cash flows if funds are deposited or removed from the portfolio(s). For example, suppose you deposited $100 into your account in the middle of the month. In that case, your portfolio's end-of-month NAV is also $100, which was not attributed to investments when you calculated your monthly return. The amount can be adjusted with different calculations based on the situation.

The modified Dietz technique is one of the well-known formulas to adjust for cash flow. Utilizing an internal rate return calculation with a financial calculator effectively adapts returns to cash flows. IRR is an interest rate that reduces an investment's net present value null. It is utilized to determine the potential profit for investment.

Annualizing Returns

The most common method is to annualize the returns of multi-period returns. This ensures that the returns are more similar across different portfolios or investment options. It creates an equal denominator in looking at the returns. An annualized return represents the geometric average of how much funds an investment makes each year. It displays the amount that could have been earned over time if the returns had been compounded. The annualized return doesn't reveal the number of fluctuations that occurred during the same time frame. The market volatility can be assessed using standard deviation, which measures how the data is distributed about its average.
