Is a Drop a Loss?

We humans use stories about events great and small to help understand the world. One of the common stories about the stock market contributes to a great misunderstanding, however.

A market decline from some higher point in the past is often spoken of as a loss. Yet whenever the market is trading at an all-time high, every past downturn has been fully recovered. One might ask where the loss actually is.

To illustrate, the decade of the 1990’s was a good one for the broad stock market, as measured by the S&P 500 Stock Index. It more than tripled, rising from 353 points to 1,469. Yet of the 2,527 trading days of the decade, 1,171 saw a decline—a drop—in the market index.1

Those down days represent a cumulative 729% in “losses.”1

In a decade when the market tripled, how does it make sense to speak of losses during the interim? Particularly losses equal to many times the beginning level?

The market is volatile. Values fluctuate. It goes up and down. But if you have long term goals, it might pay to focus on long term results, not temporary downturns. If you invest next week’s grocery money in the stock market, then yes, a temporary downturn will result in a loss when you sell out in order to buy food. Otherwise, we would say a drop is not a loss.

Note: one should never invest next week’s grocery money in the stock market.

The Monster Under the Bed

When we were small, some of us had older brothers who tried to convince us there was a monster under the bed. You may be surprised to know there is a corollary in the world of investing.

The monster promoted by some is generally called “the arithmetic of losses.” The arithmetic of losses is a simple mathematical observation that from a given number, if you take a certain percentage decrease, and then an equal percentage increase, you wind up lower than you started–even though your increase and decrease were proportionately the same. For example, if you start with $100, and lose 20%, you are at $80. If you gain 20% of $80, you’re still only back to $96. But we are here to tell you, there is no monster under the bed.

Consider that when a major stock market index declines by 50%, it then does need a 100% gain to get back to even. This is just arithmetic. But consider: whenever a stock market index is at an all time high, that is conclusive proof that the “arithmetic of losses” is a bunch of baloney.

Each all-time high means that the index has successfully come back 100% from every 50% loss, 50% for every 33% loss, 25% for every 20% loss… and MORE. Every time, every loss thus far. The long-term history of major United States stock market averages speaks for itself, and incorporates all the losses and all the gains.

Some fearmongers say investors cannot live with the ups and downs that are a necessary and integral part of long term investing. Clients, you know we work hard to ascertain whether you could be suited to our philosophy.

Part of that philosophy is that temporary declines, no matter how sharp, are not losses unless you sell out. It is not always easy, but it has worked out. No guarantees about the future, of course.

If you can be turned into a chicken, then some operator who claims to ‘control risk’ or promises short-term stability AND long-term returns may get your money. Please keep in mind that every chicken, sooner or later, gets eaten.

The fearmongers are right about one thing: markets go up and down. You and we know this. We work hard to manage the money you need without having to sell out at a bad time. This is one of the keys to being able to get through the downturns.

Clients, we are striving to find bargains, avoid stampedes, and own the orchard for the fruit crop. These principles will not prevent volatility. But there is no monster under the bed. Email us or call if you would like to discuss this or anything else at greater length.
