Mean reversion – single cluster (3.9)

Pairs trading generalised to a group of related stocks: short those that beat the group average, buy those that lagged, with positions proportional to the gap. Here the five energy stocks.

Key equation

Lab formula

lookback = 5
r = log(close / delay(close, lookback))
-(r - market(r))

How the backtest works

The formula is evaluated for every asset on every day. Its values become positions at that day’s close, using the portfolio rule you pick, and earn the next day’s close-to-close return. Costs are charged in basis points on the amount traded. Everything runs in your browser on daily data from Yahoo Finance, adjusted for splits and dividends.
