Start Bank: $198,00
Mr. Kelly's Bank: $34,53
Mr.Kelly's Start Bank: $20,00
I only managed two bets yesterday and Mr. Kelly was shut down completely. The markets were very tight with few prices out of line, probably due to the high liquidity. Anyway, the bank continued to grind away a profit to a new all-time high of $546,47.
It still bothers me that Mr.Kelly is right and I should be placing larger bets...but I really must force myself. So, I will reluctantly agree to move up to half-Kelly stakes using half of my bank, currently I am using only a quarter of my bank. Mr. Kelly has been complaining that this over over-conservative and is costing me both time and money. So, OK, fine, I'll go along...although I've got a nervous feeling about this...

SHANNON'S DEMON
Claude Shannon was a genius. He really was. He used to have some informal meetings at MIT, basically chat sessions, where he would discuss various ideas he had. They became so popular that they had to be moved to an auditorium.
One such informal lecture dealt with investing and noise in the marketplace. Shannon was very interested in noise, and the difference between noise and signals. The problem with investing in the markets, Shannon believed, was that there was too much noise -- the markets wandered up and down in a random walk most of the time. (And that's true if you think of it...if the stockmarket rises 10% over a year, that's 10% divided by 365 days...0.027% per day...that's almost nothing)Shannon believed it was far better to invest in the noise rather than try in vain to find the signal like most investors.
But how do you invest in noise? Shannon proposed an investment plan that looked like this: Take 50% of your money and invest it in stocks and 50% in cash. When the market rises, your stocks will be worth more than 50% of your total, so you sell them to return to 50%. When the market falls, your stocks will be less than 50%, so you buy more to return to your original 50% level.
What happens over time by always keeping a 50-50 balance is that you are buying "high" and selling "low" most of the time and harvesting the market noise. At the end of the year, the market may not have moved much, but you have gained all the up-and-down noise.
Someone asked Shannon if he used this method himself and he said no. The transaction costs in those days were far too high. That, and the taxes, would have made it unprofitable for Shannon to use.
Nowadays, this portfolio rebalancing is well-known and encouraged. Yet, few investors actually do it.
Times have changed since Claude Shannon's day. With most index and mutual funds today you are sheltered from taxes and transaction fees. And it doesn't have to be stocks. You can set up your own "demons" using gold, foreign currency or other assets. As long as the transaction fees and taxes are low, and you rebalance often and stay in it for the long term, you can profit substantially from Shannon's Demon.
Next time, I will talk about why it works and how it is connected with John Kelly and the Kelly Criterion.
