A Case Against Market Timing
A customer wrote us yesterday and told us that they didn’t need our advice right now because they had pulled all their money out of the market and put it into the money market fund in their account. While this is not the first time this has happened, it still bothers me a great deal whenever I hear about it.
There are certainly very legitimate reasons to move your retirement money into a cash-equivalent investment like a money market or stable value fund. When you don’t have the time to ride out shorter-term ups and downs of the market, you may need to get more conservative with your money. But the more frequent reason people pull out of the market is flat out nervousness. Many people that get nervous about the markets are tempted to pull their money out before (they think) things could get worse. When the market starts to go back up, the plan is to jump back into their original investments, reaping the rewards of future market gains.
Well, I’m here to tell you two things:
1. Pulling out of the market whenever you fear further declines is a form of market timing
2. Market timing is extremely risky and can easily cost you tens of thousands of dollars if your timing is off the slightest bit. Read on to get the facts.
Goldman Sachs Asset Management did a study that looked at market returns as represented by the S&P 500 Index from 1986 to 2006. Here is what the data shows:
Stay invested in all 5,297 days of this study period, and the annual return is 12.12%
Miss the 10 best days and the annual return is 8.56% - a difference of 3.56% per year.
Miss the best 40 days and the annual return drops to 1.87%.
Miss the best 70 days and the annual return drops to -3.02%.
As the data above indicates, if you are out of the market only a handfull of key times, your returns can be severely impacted. What does this return difference mean in terms of dollars in your account at retirement? Let’s say you just missed the 10 best days over the above 20 year period, saved $400 per month for all of those 20 years, and had a return on your investments of 8.6% (rounded for our calculator) per year. You would have $254,500 after the 20 years. Under the same assumptions, except if your return were instead 12% per year (rounded for our calculator), you would have $ 399,700 - a difference of over $145,000 (these are before tax numbers). And that’s only 10 days! Imagine if you had missed the top 70 days, just over 1% of the days covered in the time period, and lost money!
Given these numbers, is it really worth the risk of going in and out of the market? We think not.

When you recommend changes to someone’s 401k plan, isn’t that a form of “market timing”? What makes you think you are better at timing the market than anyone else?

After reading this, I guess I will stay in the market. My stomach is in turmoil, but I am open to your advice……..

John,
Good question… True market timing deals more with moving in and out of the market in an effort to predict short-term market gyrations. The changes we suggest at Smart401k, focus on asset classes that we feel are overvalued/undervalued in relation to others as well as to portfolio optimization. Our goal is to find the combination of asset classes that offer the highest potential future return for the level of risk that each client is comfortable taking on.

I belive you were talking about me in your first paragraph. I thought about it for awhile, then left 55% into the money market account I have here at work and distributed the other 45% accordingly. The first day I lost almost $2900, first day! But I kept it in those accounts and now am moving back to having my original investment. Since I have 4 or 5 years til retirement, I will keep it diversified as you state, but only part of it…..I am still extremely nervous about the market. Here at my Federal job, 401K is at least 75% of my retirement.
