Sector Rotation Clock

GICS sector ETFs. Relative strength is the ratio of trailing N-period returns vs the benchmark, momentum its period-over-period change — distinct from the JdK RRG. Each sector spirals out from the center over time. Read it as a positioning map, not a forward signal: backtested over 20y the leadership octants don't predict outperformance (the RS axis is mildly mean-reverting at 1–3 month horizons) — context, not buy/sell.
