The art of backtesting – techniques & war stories from practitioners

  • Filtering published research – appropriate benchmarks, survivorship bias, transaction costs, robustness over time, regime changes, scalability
  • Dealing with data – gathering and trusting data, identifying bad records, techniques for dealing with missing data, alignment and synchronization, data adjustment (dividends, splits, future rolls, etc.)
