Last week, in my Nov. 18 column, I sketched out a picture of a very volatile 2011 and said that today I'd take my best shot at a strategy for how to invest through the turbulence.
I probably shouldn't be telling you this, but most of the time investing is pretty simple: Follow the trend with your money and get your emotions out of the way. And that's also the key to even as turbulent a year as 2011 promises to be.My strategy is based on taking advantage of that "most of the time" and staying alert for the exceptions.
Markets love trends
Most of the time, markets are in a trend. Look it up yourself on a chart of something as staid as the Standard & Poor's 500 Stock Index ($INX) or something as supposedly volatile as the iShares MSCI Emerging Markets Index (EEM, news, msgs).If you graph the market's daily moves along with its 200-day moving average, you'll see that while the daily moves create a mountain range of jagged peaks and valleys, the smoothing average reveals a remarkably steady trend line.
So from March 2003 to December 2007, you'll see a 200-day moving average draw a very steady ascending slope. That's despite the big valleys caused by daily moves like those of March 2007, or the big peaks caused by daily moves like those of July 2007.
Long-term trends are your friends
If you play around with these charts, a couple of really important investing truths pop out at you.First, the longer your holding period is, the less important the volatility on the daily chart. Peaks and valleys fade into insignificance when you're looking at an upward-trending 200-day moving average from March 2003 to December 2007 or from May 2003 to June 2008.
This observation can easily get extended into something like the extreme form of what's called buy-and-hold investing, which argues that if your holding period is long enough, you need never sell stocks. You just hold on through any volatility.
Second, it's clear from looking at these charts that this extreme form of buy and hold isn't very good advice. And that's because these "most of the time" trends are punctuated by bouts of volatility that are big enough to completely reverse the 200-day or any other trend line.
The volatility from January 2008 through August 2009 (otherwise known as the global financial crisis or the bear market of 2007) decisively ended that March 2003-to-December 2007 upward trend. Same thing happened in the volatility that stretched from November 2000 to April 2003 (otherwise known as the tech bubble or the bear market of 2000).
Even if you draw a chart all the way back to 1950, you will see clearly these great trend-busting events. Some volatility is big enough to get your attention no matter how long your holding period.
