Turnover Index - Week 14

Here are the Turnover Index picks for Week 14. The Turnover Index is a simple betting strategy based on the theory that the market overvalues defensive turnovers when judging team strength. See here and here for more background.

Week 13 results

Our week 13 bet was successful against the spread (the Jets covered against Miami in a losing effort). Here are the season to date results:
  • Against the Spread: 7-2
  • Starting Bankroll: $1,000
  • Current Bankroll: $1,073 (7% ROI)
And here are the week by week results:

Week 14 Picks

There is just one bet against the spread this week (the Raiders to cover against the Niners). We are wagering 0.6% of our bankroll. The table below shows the turnover differential, probability of covering, and the recommended fraction of bankroll to bet, according to the Kelly Criterion.

The "Old" Index

Under the original, simpler betting approach (bet any game with at least a 10 defensive turnover differential between the teams), season to date results for 2014 are 6-2 against the spread.
