Understanding bear market arithmetic
Thursday, April 30th, 2009One of the more confusing aspects of the financial markets is that so many numbers are casually thrown around. There are fractions, percentages, decimals, currencies, and more.
During market downturns, it is easy to get mixed up about what is lost and what is gained. Let’s explain some bear market arithmetic using some simplified numbers. Say we start with an investment of $1,000. Imagine that the investment loses 60%. Now we have an account that has lost $600 after starting at $1,000. That leaves $400 in the account.
If there is a bear market rally of 25% many people mistakenly believe that the market gained back one-fourth of what was lost. It is important to remember that we are now talking about 25% of $400 and not 25% of the original account value. A 25% gain amounts to $100 and takes the account value to $500. So while a 25% gain sound impressive, it is really only 10% of the original value of the account. Even after a 25% gain, the account is still down 50% from its original value.
The chart below illustrates what has actually occurred with the S&P 500 during this current bear market. Since the most recent bottom in March 2009, the S&P 500 has advanced 33%. Although that sounds impressive, an investor who experienced the full 58% decline in his account value has only regained 23% of what was lost.
So the only people who have seen a 33% gain in their accounts since March would be those who were out of the market for the decline and who were perceptive and brave enough to buy in at the exact low point. After watching the S&P 500 lose 58% in the prior 16 months, I doubt there were many investors who recognized the bottom and were willing to jump in at that time.
I must admit that I would have liked to reap the rewards of that 33% gain. That is an unusually large bear market rally. But our indicators continue to show that the current advance is overextended and past due for a reversal. Buying at this point would be imprudent and could very easily result in a significant loss if stocks turn down again. And as the illustration above shows, avoiding losses is important in protecting the value of an investment account.
