Sector Rotation Strategy

Research suggests a large share of a stock's return comes from its sector. When gold miners rise, most gold names rise; when energy crashes with oil, even the best producer falls. By being in the right sector you capture the majority of the move without needing to pick the single best stock.

Review rankings weekly but only rebalance monthly or when significant rank changes occur (3+ positions). A minimum holding period of 10 days prevents excessive turnover. Typical rotation holds sectors for 2-8 weeks before switching.

If no sector is outperforming the Composite (all RS < 1.0), the market may be in a broad decline or highly correlated - common in Canada when Financials, Energy and Materials all sell off together. Options: 1) raise cash (a HISA or money-market ETF), 2) focus on the least-negative RS sectors, 3) add defensives (Utilities/Staples or Gold) regardless of RS. This is a 'no sector leadership' signal.

Not recommended. Concentration in one sector creates high risk if it reverses - and on the TSX the top sector is often a volatile commodity group. Diversifying across the top 3 (subject to the correlation cap) provides better risk-adjusted returns. Maximum 25% in any single sector is the guideline.

For ETF-based rotation, roughly C$10,000-25,000 is enough since ETFs are cheap and cover most sectors. For leader-stock baskets (needed for Industrials/Discretionary/Communication), C$25,000-50,000 lets you hold several positions. MX sector futures carry large notional and are thin, so futures-based rotation realistically needs C$150,000+ and is more of an institutional approach. Start with ETFs if capital is limited.

Industrials, Consumer Discretionary, Communication Services and Health Care have no liquid domestic capped-sector ETF, so build a basket of 3-5 leader stocks with equal weight. Example: Industrials = CP + CNR + WCN; Communication = BCE + T + RCI.B. This gives sector exposure with stock-level flexibility, at the cost of more positions to manage.

Best results come from combining both. RS is backward-looking (what is working now); the cycle is forward-looking (what should work next). In Canada the inflation/rate regime is especially important because commodity sectors are so large. Use cycle/commodity analysis to anticipate leadership, then confirm with RS. Cycle + RS aligned = highest conviction.

Long the leader + short the laggard simultaneously; you profit from relative outperformance regardless of market direction. Beta-adjust sizes. Because MX sector futures are thin, most rotators express pairs with sector ETFs (long one, short another) or a US-listed proxy for an easier borrow. Example: long XGD (gold) + short a telecom basket. Monitor the spread, not the individual legs.

Common failures: 1) highly correlated 'risk-on/risk-off' markets where Financials, Energy and Materials move together (frequent on the TSX), 2) sudden macro/commodity shocks that override technical signals, 3) over-rotation in choppy markets (whipsaws), 4) ignoring fundamental drivers (oil, gold, BoC). Use filters and macro awareness to reduce failures.

Three approaches: 1) protective puts on long sector ETF positions, 2) covered calls for income (or packaged covered-call ETFs like ZWB/ZWU/ZWE), 3) leveraged rotation using ETF calls instead of shares. Note that Canadian single-name and ETF options are thinner than US ones, so favour the most liquid (SXO index options, XIU/XIC and large sector ETFs) or US-listed proxies.

Multi-factor approach: RS momentum (35-40%), RS ratio (25%), Trend (20%), Breadth (15%), Volatility (5%). Walk-forward optimise over 10+ years and adapt to regime. The key Canadian addition is a correlation/cluster constraint plus explicit oil and gold macro factors, because Financials/Energy/Materials dominate the index. Target 3-5% alpha over the Composite, Sharpe > 1.0, information ratio > 0.5.

Typically RS momentum, sector breadth and distance from moving averages, plus Canada-specific macro: WTI/WCS oil, the gold price and US real yields, BoC policy-rate changes and CAD/USD. Cross-sector relative ranks capture competitive dynamics. XGBoost/Random Forest are effective for this tabular task; oil and gold features carry unusually high importance on the TSX.

Risk parity weights by inverse volatility, so each sector contributes equal risk. Low-vol sectors (Utilities, Staples) get more weight and high-vol sectors (Gold, Energy, Materials) less. Given Canada's very large cross-sector volatility gaps, this materially improves the Sharpe ratio and reduces drawdowns from commodity blow-ups versus equal weight.

Core (40-50%) in a broad index (XIC/XIU) for beta; rotation sleeve (30-40%) for active sector alpha; tactical (10-20%) for special situations; defensive (5-10%) in gold/bonds. Crucially, because the core is already Financials/Energy/Materials-heavy, track the sleeve's overlap with the index and favour diversifying sectors when they lead. Monthly rebalance with threshold triggers.

Key metrics: absolute return, excess return vs the S&P/TSX Composite (alpha), Sharpe ratio, information ratio (alpha consistency) and max drawdown. Attribution: sector selection vs timing vs sizing. Correlation with the benchmark (lower = better diversification). Target 3-5% annual alpha, Sharpe > 1.0, correlation < 0.8.
