The primary Z-score for this trading system (often called the System Quality Number or SQN) is 9.30.
• What this means: In statistical terms, a Z-score of 9.30 implies the average return is over 9 standard deviations away from zero. For context, a Z-score of >3.0 is considered "Superb," and anything >7.0 is typically classified as "Holy Grail" territory.
• Probability: The probability of achieving this result by pure random chance (luck) is virtually zero (p < 0.0000000000000000006).
To measure skill in finance, we use the Sharpe Ratio (Risk-Adjusted Return). It measures how much return you generate for every unit of volatility (risk) you endure.
• The Options SellerData's Annualized Sharpe Ratio:11.49
• Her Data's Sortino Ratio (Downside Efficiency):35.06
This score is statistically absurd. In the world of professional trading, a Sharpe Ratio above 3.0 is considered "Holy Grail" territory. A score of 11.5 implies you are effectively printing money with almost zero variation in your equity curve.
Comparison: The Hall of Fame
To put the 11.49 score in perspective, here is how it compares to the verified records of the best investors and funds of all time:
1. Warren Buffett (Berkshire Hathaway)
• Sharpe Ratio:~0.79
• Strategy: Long-term Value Investing.
• Verdict: Buffett became the richest investor not by having a high Sharpe (smooth ride), but by enduring massive volatility (drawdowns of -50%) over a very long timeframe (50+ years).
2. The "Fraud" Benchmark: Bernie Madoff
• Sharpe Ratio:~2.50 – 4.00
• Strategy: Ponzi Scheme (Faked "Split-Strike Conversion").
• Verdict: Even Madoff, who could make up any numbers he wanted to fool banks, did not dare to fake a Sharpe Ratio as high as 11.5. He kept his fake numbers in the 2.5–4.0 range to make them look "believable" to sophisticated investors.
3. The "GOAT": Renaissance Technologies (Medallion Fund)
• Sharpe Ratio:~6.0 – 7.0 (Estimated after fees).
• Strategy: High-Frequency Quant Arbitrage (Jim Simons).
• Verdict: This is widely considered the greatest money-making machine in history. They use supercomputers to trade milliseconds. Your data claims to be nearly twice as efficient as the Medallion Fund.
4. The Only Real Equivalent: Virtu Financial (HFT)
• Record: 1 losing day in 1,238 trading days.
• Strategy: Market Making / High-Frequency Trading.
• Verdict: The only entities that achieve stats similar to your file (90%+ win rate, Sharpe >10) are HFT firms that don't "predict" the market but "front-run" order flow using nanosecond speed advantages.
