Larry Hite on Risk

Some wise views from Larry Hite:

“We don’t really trade silver…we don’t trade the S&P…we trade the differences. We really are risk managers. We take on risks, try to exploit them and we leave when they turn against us. That is what we get paid for. Basically we are in the risk transfer business. We take on what people want to sell, sell what people want to buy and hope to make a profit. The reason why one goes to a portfolio is because there are real limits to perfect knowledge. I’ll give you an example. Say you knew which commodity, stock or currency would appreciate the most in the following year, and you knew exactly what its price would be. We did this experiment looking backwards in fact in our database. The question of when you take a position is how are you going to trade the line…how much of a position are you going to leverage. Now, if you have perfect knowledge, would you leverage 5 to 1, would you leverage 10 to 1, 2 to 1? Well it turns out that if you leverage more than 3 to 1 that you are a loser. Because we found that if you did 3 to 1 you would have, even with perfect knowledge, you could go down a third. So that, the only perfect knowledge you could have, would be if you knew every wiggle on the line. Then you would know exactly how much to leverage. But you don’t.”

Note: No vulgarity or ugly attacks. There are other places for that.

    Over what period and what instruments was Hite’s 3:1 ruin constant observed I wonder? Interesting to connect the dots here.

    So, assume the bet is once per year (eg: yearly high or low is known) and you put your bet on at the earliest point when the market is going in the ultimate direction along with a closing order at the apriori known high or low.

    Now going forward. Given you didn’t know which way; or how high/low, you would have to pick from say 10 bets on different instruments, 5 long and 5 short. Also given you don’t know how high or low you close the ones that lose 33% or more and hold the profitable ones that go against you less than 33% from highest or lowest point.

    Assuming this constant is reliable over a portfolio, you should lose 5/10 x .67 = .34 of your collateral to the losers and still be in the game on the other 5/10 x 1.00 = .50 resulting in an average risk factor of about 1-(.34+.50=.84) = 16% in order to play the game.

    Without more information about how the positions are opened and closed per year or whatever period, there are some complications however. Among other things, if you have a winner that hasn’t backtracked 33% from high/low by year end, do you count it in next year’s 10 bets?

    Food for thought anyway. Any more detail on the rules of the experiment Michael?

    I would argue that the length of “the line” determines your trading pattern. A scalper’s line might be an hour long, a typical trend follower a few weeks to a year, and Warren Buffet’s might be 10 years. There are lots of wiggles along the way, but it depends on your holding power. No one method is more successful than any other it’s just how we view the markets.

  • Dave Bickings

    No wonder this guy (Hite) is a legend in this industry! He is disciplined, calculatingly aggressive, and humble enough to know that he can’t predict what happens tomorrow.
