I said that manager B knows the expected outcame not the exact next outcome. Same as a casino knows his expected gain on a roulette wheel not what will be the next number.
Assume that you know that the S&P500 has grown at an AVERAGE annual rate of 10%, assume that this grow will not change in the future (and you are the only one to know this) and assume the the distribution of returns is lognormal, is it possible to make risk free money on this knowledge? We find no. Options are priced on risk neutral basis, they assume all stocks will grow at the risk free rate.
However what about a CPPI strategy instead of buy and hold? Can CPPI give us superior risk-adjusted returns?
