Set forth below is the text of a comment that I recently posted to the discussion thread for another blog entry at this site:
What do you consider long term timing and when have you been successful in getting back in the market?
Short-term timing is trying to guess when a price change will take place and to profit from it. Long-term timing is changing your stock allocation because the level of risk associated with that stock allocation has changed and you want to keep your risk profile constant over tine.
An effort to engage in long-term timing is successful at the moment it is made because that is the moment when the risk profile is corrected. I don’t think that it is possible for an effort in long-term timing to fail, not any more than it is possible for an effort to engage in price discipline to fail when making purchases in any other market. If someone pays less for a car because he engages in research and negotiates with the dealer, I don’t see how that effort could produce bad results. He may end up getting the wrong car because he didn’t know his own mind well enough. That sort of thing can happen in the stock market. You could engage in market timing to adjust to your preferred risk profile and you could determine years later that you chose the preferred risk profile improperly. That doesn’t show that price discipline (market timing) is a bad thing. It shows that our execution of it is going to be imperfect because our knowledge of the subject is imperfect.
That’s not an argument for failing to engage in market timing (price discipline), it is an argument for expanding our knowledge of the subject. Which of course requires opening every investing site on the internet to honest posting re the last 39 years of peer-reviewed research in this field.
