The central problem for gamblers is to find positive expectation bets. But the gambler also needs to know how to manage his money, i.e., how much to bet. In the stock market (more inclusively, the securities markets) the problem is similar but more complex. The gambler, who is now an “investor”, looks for “excess risk adjusted return”. In both these settings, we explore the use of the Kelly criterion, which is to maximize the expected value of the logarithm of wealth (“maximize expected… Expand

Rebalancing Frequency Considerations for Kelly-Optimal Stock Portfolios in a Control-Theoretic Framework
• Economics, Computer Science
• 2018 IEEE Conference on Decision and Control (CDC)
• 2018
It is shown that if there is an asset satisfying a certain dominance condition, then an optimal portfolio consists of this asset alone; i.e., if the trader puts “all eggs in one basket,” performance becomes a constant function of rebalancing frequency, and the problem ofRebalancing is rendered moot.

On inefficiency of markowitz-style investment strategies when drawdown is important
• Economics, Mathematics
• 2017 IEEE 56th Annual Conference on Decision and Control (CDC)
• 2017
The focal point of this paper is the issue of “drawdown” which arises in recursive betting scenarios and related applications in the stock market and a new investment strategy which involves a time-varying linear feedback block K (k), called the drawdown modulator, which results in classical Markowitz-style strategies are inefficient.
