Best Moving Averages for SPY, QQQ, and DIA
| Moving Average | Purpose |

Each of these moving averages helps you interpret different market phases.
SPY (S&P 500 ETF)
- Above 200-day SMA: Broad market is in a long-term uptrend
- Pullback to 50-day SMA: Often a buy opportunity during healthy bull runs
- Golden Cross (50 > 200): Bullish market-wide sentiment
- Death Cross (50 < 200): Risk-off or recession warning
Tip: SPY reacts well to 50-day SMA in strong uptrends. Many fund managers use this level to rebalance portfolios.
QQQ (Nasdaq-100 ETF)
- Volatile tech-heavy ETF, so use EMA (20, 9) for faster signals
- Price often overshoots then pulls back to the 20 EMA
- Watch for bullish crossover on fast EMAs (9/20) on the daily chart
- In strong uptrends, QQQ bounces off 50 SMA consistently
Tip: Combine moving averages with RSI for better timing, as tech stocks move quickly.
DIA (Dow Jones ETF)
- More stable and less volatile than QQQ
- 200 SMA is a strong long-term reference level for DIA
- Break below the 200 SMA may suggest broader weakness in traditional industries
- 20-day EMA is less relevant here; focus more on 50 and 200 SMA
Tip: Use the 200-day MA as a market health indicator when trading cyclical or value sectors.

Breakout Strategy:
