Communicating EV to Stakeholders

## When You Bet Other People's Money Whether managing a syndicate, operating a tipping service, or partnering with an investor, you must communicate EV-based performance metrics clearly to people who may not think in these terms. ## The Problem with Showing P&L Only Short-run P&L is dominated by variance. Showing a subscriber or investor a losing month result — even one caused purely by variance on a +EV process — undermines confidence in the system. ## What to Show Instead **Primary metric: CLV (Closing Line Value)** "On average, our selections were priced 2.8% better than the closing Pinnacle line." **Secondary metric: Sample-adjusted ROI** Actual ROI with confidence interval based on sample size. "Our 350-bet sample shows 4.1% ROI with 95% confidence interval of 1.2%–7.0%." **Variance context:** "A random sequence of 350 bets with our edge profile would produce results between −2% and +10% ROI in 90% of scenarios. Our actual result of +4.1% is within this range." ## The Subscription Service Challenge Tipster services typically report ROI, win rate, and profit in units. Most hide the confidence interval context. A responsible service: - Reports the number of qualifying bets in each reporting period - Shows rolling metrics rather than cherry-picked time windows - Acknowledges variance explicitly in monthly reports ## Investor Reporting for Syndicates For betting syndicates managing external capital: - Monthly reporting: CLV, actual P&L, cumulative - Quarterly reporting: Calibration test results, market breakdown - Annual reporting: Full statistical analysis, model documentation, forward-year edge estimate Transparency about the probabilistic nature of returns — including honest downside scenarios — builds durable investor confidence.
