Great piece! did you rebalance SP/Russell every year or just use the current baskets? (constituents change every year). If so, where do you find historical constituent data? i’ve had a tough time finding that in the past trying to test strategies on index constituents

Thanks! We only trade the constituents as they existed at each point in time, so there's no lookahead into future index membership. For historical constituent data, we use Norgate Data. They provide full historical index compositions, so our backtests are free of survivorship and selection bias. Can't recommend them enough if you're doing any kind of strategy testing on index constituents. Cheers!

Guessing this doesn't include trading costs?

Speaking of dynamic sizing... and you mentioned Ed Thrope, wondering if Kelly Criterion would be a natural progression :)

Which backtesting platform are you using for this? And which account size do you see as a cap for trading such strategies on stocks in the Russell 3000?
