Episode notes
Use 5.5× ATR Above 50-Day As Extension Signal
- Watch the 50-day ATR extension (5.5× ATR) as a signal that the market is extended.
- When the index nears or breaches that line, close buying windows and consider trimming or hedging positions.
Watch The 21-Day EMA For Re-Entry Signals
- Use the 21-day EMA as a practical support level to reopen buying or remove hedges after a pullback.
- If individual stocks bounce from the 21 EMA, consider selling protection and re-entering selectively.
Measure Pullbacks From Correction Declaration
- Krull measures pullbacks from the day IBD declares a market correction until the next follow-through day.
- This framing focuses analysis on the investor experience after the market is publicly labeled 'in correction.'
