Aaron Brown, author of The Poker Face Of Wall Street, makes a strong case for the negative impact of volatility drag on expected value with respect to the Kelly Criterion in the following posts:
  * Short-Term Variance
  * Risk Of Ruin And Kelly Betting
  * Bankroll Performance Simulator
  * Betting Strategy
