Frequently Asked Questions
What is the APEX Sector Signal Index?
The APEX Sector Signal Index tracks technical momentum across all 11 S&P 500 sectors using RSI and price performance data from sector ETFs (XLK, XLF, XLE, etc.). Each sector receives a Bullish, Neutral, or Bearish signal based on its 14-day RSI and 1-week price change. This helps identify which sectors have strong technical momentum and which are showing weakness.
Which sector ETFs does APEX use?
APEX uses the 11 SPDR Sector ETFs: XLK (Technology), XLC (Communication Services), XLF (Financials), XLY (Consumer Discretionary), XLI (Industrials), XLB (Materials), XLE (Energy), XLV (Health Care), XLP (Consumer Staples), XLRE (Real Estate), XLU (Utilities). These are the standard benchmarks used by institutional investors for sector rotation analysis.
How does sector rotation analysis work?
Sector rotation is the movement of investment capital from one industry sector to another as economic cycles change. Technology and consumer discretionary sectors tend to lead during bull markets. Utilities and consumer staples tend to hold up during downturns. By tracking RSI and momentum signals across all 11 sectors simultaneously, APEX identifies where institutional money is flowing in real time.
