Abstract: Abstract The effect of anti-correlation between stocks in real stock market can be exploited for profit if one can also properly set the criterion for trading that takes into account the volatility of the stock pair. This complex problem of resource allocation for portfolio management of stocks is here simplified to a problem of adaptive trading with an investment criterion that evolves along with the time series of the stock data. The trend of the stock is modeled with standard stochastic dynamics, from which the volatility of the stock provides a criterion for investment on a two stock portfolio that consists of the anti-correlated pair using mean variance analysis that optimizes the return. The action of buy and sell of the two-stock portfolio will be based on the fractional return of the pair: when the fractional return of the pair is greater than an upper threshold of 1.01, the action “buy” is taken; and when this fractional return is less than a lower threshold of 0.99, the action “sell” is taken. Since both the volatility criterion for investment and the fractional return of the two-stock portfolio are time dependent, the entire trading scheme is adaptive. Comparison of this evolving strategy of investment with time-average performance of the respective stocks indicates a consistent superiority.
