Rules of Thumb

Practical, experience-based guidelines for navigating the economic cycle — from novice to institutional.

For Novice Investors

7 rules
  • 1If the yield curve is inverted AND ISM is below 50 → move at least 30% into defensive ETFs (XLU, XLP, XLV)
  • 2Never fight the Fed — when the Fed is cutting rates, buy stocks; when hiking, be cautious
  • 3A 10% market correction during a bull market is a buying opportunity, not a reason to sell
  • 4Consumer spending declining 3 months in a row = reduce Consumer Discretionary (XLY), add Consumer Staples (XLP)
  • 5When unemployment rate starts rising month-over-month → the economy is already in trouble
  • 6Semiconductors (SOXX/SMH) bottom before the broad market — watch them as a recovery signal
  • 7Bond market peaks before the stock market. If TLT starts falling (yields rising), stocks still have room to run

For Institutional / Advanced Investors

10 rules
  • 1Stage 1–2 (Early/Mid Expansion): Overweight XLK, XLY, XLF, XLI — underweight XLU, XLP
  • 2Stage 3 (Late Expansion): Rotate to XLE (Energy), XLB (Materials). Begin trimming tech. Add commodity exposure
  • 3Stage 4–5 (Contraction): Overweight XLU, XLV, XLP. Add TLT (long bonds). Reduce overall equity beta
  • 4Stage 6 (Trough): Accumulate XLK, XLF, XLY. Buy small caps (IWM). This is maximum opportunity
  • 5Yield curve uninversion (after inversion) = recession imminent. This is MORE dangerous than inversion itself
  • 6When ISM rebounds from below 45 back to 50 = manufacturing recovery signal — buy Industrials (XLI) and Materials (XLB)
  • 7Crack spread widening (CRAK) → energy sector strength. U.S. refiners are early movers
  • 8Monitor HYG/TLT ratio daily — tightening spread = risk-on; widening = risk-off
  • 9Small caps (IWM) lead recoveries. If IWM outperforms SPY by 5%+ over 3 months = early expansion confirmed
  • 10Earnings recession (2 quarters of falling EPS) at market highs = major correction likely within 6 months

Bond Market Rules

7 rules
  • 1Bond prices and bond yields move inversely — when you hear 'yields rising', bond prices are falling
  • 2Rising yields = bond traders expect economic growth + inflation ahead (sell bonds before rates rise more)
  • 3Falling yields = bond traders fear deflation or recession (buy bonds as safe haven, prices go up)
  • 4Bond market bottoms 3–6 months before stocks bottom — the first sign of recovery
  • 5Bond market peaks 3–6 months before stocks peak — the first sign of cycle turning
  • 610Y-2Y inversion has preceded every recession since 1950. It's the single most reliable signal
  • 7When the Fed pivots from hike to cut → long-duration bonds (TLT) benefit enormously

Sector Rotation Rules

7 rules
  • 1Early Expansion: Technology → Consumer Discretionary → Financials (in roughly that order)
  • 2Mid Expansion: Industrials → Materials → Real Estate
  • 3Late Expansion: Energy peaks last in expansion. Don't chase it too far
  • 4Contraction: Health Care holds best first, then Consumer Staples, then Utilities
  • 5Recovery: Financial sector leads — a steepening yield curve means bank profits rebound first
  • 6Defensive sectors (XLU, XLP, XLV) should ALWAYS be part of a balanced portfolio
  • 7Sector rotation is not instant — transitions take months, not days
