Applying Parrando’s paradox to the stock market
Sunday, December 2nd, 2007I found this article in the nytimes (from Jan. 2000) about Parrando’s paradox very interesting. Two losing games can be combined to create a winning strategy.
Economists are studying Parrando’s paradox to help find the best strategies for managing investments. Dr. Sergei Maslov, a physicist at Brookhaven National Laboratory in Upton, N.Y., recently showed that if an investor simultaneously shared capital between two losing stock portfolios, capital would increase rather than decrease. ”It’s mind-boggling,” Dr. Maslov said. ”You can turn two minuses into a plus.” But so far, he said, it is too early to apply his model to the real stock market because of its complexity.
I’m dying to know more about this. Anyone heard of it being used in the market?
I’m also headed to Las Vegas this coming weekend - maybe if I alternate between craps and blackjack I can make millions.
I was disappointed to read this:
Unfortunately, Parrando’s paradox will not work for the kinds of games played in casinos, Dr. Abbott said. Games A and B must be set up to copy a ratchet, which means they must have some direct interaction.
Wikipedia also says that this theory won’t work in the stock market for the same reason.
There must be a way. Maybe I can figure something out on the 5 hour flight to Vegas.
