VIX: A Market Timing Tool

Jake, Here is a very simple tool for timing the market. I don’t understand the complexity of some other models that are promoted, so I don’t use them. But I could have really used a simple tool to manage this bear market.

Take a look at the attached 5 year chart for VIX. Notice how VIX provides an excellent indicator for major tops and bottoms. When the daily VIX moves below the 100 day moving average and stays there for 10 days, it is a buy signal. A major buy was given by this indicator on March 31, 2003, which if you remember, was about 10 days after the market made its major low (at the start of the Iraq war) and began a five year bull run. When the opposite happens, like on February 25, 2007, it is a sell signal. VIX went back below the MA on April 2, so a buy would have occurred 10 days later on April 12. You could have bought back in for another 2 months without much conviction from the VIX.

It skidded around along the moving average until May 23 when it broke above the line for good creating another sell signal 10 days later on June 6. The July 19 top and selloff (with the Bear Stearns sub-prime hedge fund implosion) resulted in a big spike in volatility, but vol had already moved above the average. But you wouldn’t have given up much in gains by using this timing signal (DOW moved from 13,591 to 14,000 in that time or about 3%). With a 10% selling program, 80% of the portfolio would have benefited from the rise, saving 20% of the portfolio from what was to follow. Better yet, if we require a 5% move below the VIX moving average in order to buy, or 1.0 on the VIX scale, we would have not had a buy signal on April 12 and would have just kept on selling from the start on March 5 when the DOW hit 12,050. We would have had 40% of our portfolio moved out of stocks by July 19 and been 100% out by December.

As of now, we are way above the buy signal which is at about 18 on the VIX. We will need to fall back to that level and stay under it for 10 days. Then the coast should be clear, if past teaches us anything.

You will also notice there would have been a move out and back in the market in mid 2006 when the market tanked in May and June. But if you use a gradual approach in and out of the market, maybe 10% of the portfolio a month, it would not jerk you around much. Using a 10% per month rule, you would have been completely out of the market by November after the February sell signal which triggered in March (after the 10 day waiting period). It would have been hard selling in April to June as the market kept climbing, but this is why a system is so important.

I plan to use this timing signal in the future as I did not have much discipline this last downturn. Despite a correct reading on the potential problems for the market and the magnitude (so far) of the breakdown, I kept putting my funds back into the market too soon after selling and before volatility had fully subsided, causing needless losses along the way.
