Quick Answer
The ETF Rotation Monitor ranks 15 major ETFs by trailing 3-month return using the dual-momentum method: the top 3 qualify only while their momentum is positive, otherwise the slot defaults to cash. It is a transparent, math-only ranking refreshed from end-of-day data.
Frequently Asked Questions
What is ETF rotation and how does dual momentum work?
ETF rotation is a systematic approach that periodically ranks a fixed basket of ETFs by recent performance. Dual momentum, popularized by Gary Antonacci, combines two tests: relative momentum (rank all ETFs by trailing 3-month return and take the strongest) and absolute momentum (only keep a leader while its own trailing return is positive — otherwise that slot sits in cash). The combination historically reduced deep drawdowns compared with buy-and-hold in academic studies, though past results never guarantee future returns.
Which ETFs does the rotation monitor track?
The basket holds 15 liquid, low-cost ETFs chosen to cover the whole market: SPY (S&P 500), QQQ (Nasdaq 100) and IWM (small caps) for US indexes; the SPDR sector funds XLK, XLF, XLE, XLV, XLY, XLI, XLP and XLU for the major GICS sectors; EFA and EEM for international developed and emerging markets; TLT for long-term Treasuries; and GLD for gold. ETFs do not delist the way single stocks do, so the ranking is free of survivorship bias.
Why a 63-day lookback and top 3?
The parameters are pre-specified rather than tuned: 63 trading days is roughly three months, the momentum window with the most consistent evidence in academic literature, and holding the top 3 balances concentration against diversification. Fixing the parameters in advance avoids curve-fitting — the temptation to keep adjusting settings until a backtest looks good, which usually fails in live markets.
What does the risk-on / risk-off regime badge mean?
The regime badge compares the S&P 500's latest price with its 50-day and 200-day moving averages. Risk-on means price is above the 200-day average and the 50-day average is also above it — the classic definition of an uptrend. Risk-off means both conditions point down. Anything in between is labeled mixed. It is a slow, deliberately simple trend gauge, not a prediction.
Is the ETF rotation monitor investment advice?
No. The monitor is an educational visualization of a well-documented systematic rule. It shows what the rule currently ranks, not what you should buy or sell. Momentum strategies can underperform for long stretches, whipsaw in sideways markets, and generate taxable events. Always do your own research and consider consulting a licensed financial advisor before acting on any strategy.
How often does the ranking update?
Rankings are recomputed from end-of-day closing prices and cached for up to 12 hours, so the page reflects the most recent market close. The underlying dual-momentum rule is typically evaluated monthly by practitioners — daily moves rarely change the leaders, which is part of the strategy's appeal: it is slow by design and ignores intraday noise.
