Interesting seasonal 6mo in 6 mo out investing theory

[BTDretire]

I ran across a page suggesting a seasonal 6mo in 6 mo out investing theory, uses past data to show it's positive effect.
Page down about 1/2 way until you see, "May 7, 2012, Bob Brinker's Moneytalk Summary Part Two"
and read David Korn's comments.

The biggest market gains usually happen during a very short period of time.  The key is to be in the market at that time.  You could probably have good gains being in the market for only 3 months and out the other 9.

All you have to do is be able to predict which months to be in the market and which to be out.

Bob Brinker's newsletter is called Market Timer after all.

The last few years have been tough times for market timers. Low volatility and a market that has gone straight up.

 You missed the point the proper 6 months is already picked for you.
 But you well note, Brinker had nothing to do with the theory nor would he recommend it.
Also the weblog you were on is all about hold Brinkers feet to the fire.
