Turnover Index - Week 13
Here are the Turnover Index picks for Week 13. 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 12 results
Our week 12 bets went 1-1 against the spread. Our bet on the Redskins was successful, but we only wagered 0.8% of our bankroll. Our bet on the Jets was unsuccessful (to say the least), and we had a higher stake on that game: 1.7% of our bankroll. Here are the season to date results:
- Against the Spread: 6-2
- Starting Bankroll: $1,000
- Current Bankroll: $1,066 (7% ROI)
And here are the week by week results:
| week | bets | won | starting bankroll | amount bet | profits | ending bankroll |
|---|---|---|---|---|---|---|
| 7 | 2 | 2 | $1,000 | $51 (5.2%) | $47 | $1,047 |
| 8 | 2 | 1 | $1,047 | $26 (2.6%) | $1 | $1,048 |
| 10 | 2 | 2 | $1,048 | $32 (3.1%) | $29 | $1,077 |
| 12 | 2 | 1 | $1,077 | $26 (2.5%) | ($11) | $1,066 |
