Total Return is calculated by taking the total dollar amount an investor has gained from holding a bond and dividing it by the initial purchase price of the bond. It includes all of the below factors:
- Simple interest
- Interest compounded on interest
- Changes in the bond’s market price
- Any other payments received or made (for example commission paid on a transaction to buy a bond).
Financial institutions do a total return analysis on their bonds and other securities on a daily basis. This is known as “marking to market” and provides better and more up to date information on performance of financial products and potential risk to different events in the market.
Total Return vs. Yield to Maturity (YTM)
To understand, the current profit or loss of a bond investment an investor needs an alternative tool to Yield To Maturity (YTM). YTM includes certain assumptions about the future that may not play out, namely:
- That the investor holds the bond until maturity. Many investors sell their bonds prior to their maturity date.
- That the the coupon payments received on the bond are reinvested at the YTM rate. Interest rates are likely to change over the life of a bond and coupon payments are therefore likely to be reinvested at a different rate than the YTM rate.
In comparison to YTM which is forward-looking, total return assesses past performance up till a given instant (such as the current day). As Total return looks at the past there are no assumptions that need to be made in the calculation. Because of this fact total return is the most accurate gauge of the performance of a bond investment.
Using Total Return to Evaluate Investment Strategy
Total return is of particular interest to investors who pursue an active trading strategy and who seek to buy a bond when its price is low and sell when it is high, instead of holding to maturity. It also allows investors to compare projected YTM with total return to date, to evaluate the desirability of a buy and hold strategy (no trading commissions to be paid, pre-defined principal paid to investor at maturity) compared to an active trading strategy (trading commissions to be paid, market price of bond may go up or down).
