A basic problem of logic
October 11th, 2008. Posted by: Josh Friedlander.Today’s NYTimes contains an article by Ron Lieber that I’ve read hundreds of times in different guises by different authors.
The basic argument is “buy and hold”: keep your money in the stock market during this blip because you’ll be sorry if you miss a resurgence. Articles like this explain that, yes, it would be great to put money in cash and wait until the market decides to rebound, but there’s no way to know when that is, so you’d better stay invested.
A guarantee of a small loss may sound good right now. But if you’re not bailing out of stocks once and for all, how will you know when it’s time to get back in? The fact is, any peace of mind you gain by being on the sidelines now will turn into a migraine once you see how much you can harm your portfolio over time by missing just a bit of any rebound.
What always strikes me as funny is the basic logical fallacy of this argument. The author says if you sell now you’re market timing and no one can know when to get back in, but at the time time he’s basically telling you to invest NOW. There is no actual distinction between not redeeming money now and putting in new money. They work out to the same result, and both actions involve timing.
Since there was no way for me to comment (why do some NYTimes articles allow comments and others do not?), I wrote the author an email, adapted from my post of the other day: Read the rest of this entry »
