Trading Strategies Performance
XT99 Diversified Program
This was Pardo's flagship trading program for over a decade:
- The XT99 Diversified program ran from 1999 to 2012, producing a 19% Annualized Rate of Return on maximum capital of $40 Million.
- It earned top rankings by BarclayHedge and other rating services on over thirty-five occasions.
- In 2008, Pardo was featured as one of the top traders in Futures magazine after XT99 posted gains of +142%, followed by a loss of 49% in 2009 and then a gain of 25% in 2010.
- The program traded a dynamic portfolio of over 50 liquid futures markets across eight distinct sectors, selected via a proprietary algorithm.
Following the success of XT99, Pardo developed a more sophisticated program:
- Pardo Renaissance Diversified is described as "a state-of-the-art, highly diversified, algorithmic trading program" with pro forma returns of an Annualized Rate of Return of 29.98% and a Sharpe Ratio of 2.5, which exceed those of XT99.
- Renaissance was designed to address the volatility issues that affected XT99, with Pardo noting that "a loss like we experienced in 2009 is as close to impossible for Renaissance as it can be."
Pardo & Company now offers several strategy portfolios:
- Ranger Alpha 2022: 60-minute trading strategies on stock index futures, energy, and agricultural markets
- LDR Alpha Portfolio: A collection of 60-minute trading strategies on a small, diversified portfolio
- LDR Bitcoin Portfolio: Six 60-minute trading strategies on Bitcoin futures
- Cross Alpha Portfolio: 60-minute trading strategies on a diversified portfolio
Walk-Forward Analysis
Pardo's most significant contribution to trading strategy development is the Walk-Forward Analysis methodology:
- In 1991, Pardo developed this ground-breaking methodology, now considered the "gold standard" for strategy optimization and validation.
- Walk Forward Analysis involves optimizing a strategy on a training set, testing it on out-of-sample data, then rolling forward and repeating the process, examining the combined results of multiple out-of-sample periods.
- This approach simulates real-world trading by "rolling" the optimization window forward over time, creating a backtest of entirely out-of-sample results, which helps strategies adapt to evolving market conditions while avoiding overfitting.

Strategy Development Process
Pardo's approach to strategy development emphasizes robustness testing:
- His 9-step Strategy Development Process focuses on creating trading strategies that actually work in live trading, with robustness as a key aspect.
- His proprietary strategy validation process is based on an application of his Walk-Forward Analysis, which has been refined and improved over the years.
- Pardo's process includes analysis of the "Optimization Space" to uncover important details about a trading strategy hidden in optimization results, and proper selection of optimization parameters, ranges, resolutions, and market history.
