DCI Forecast



Bearish<—>Bullish



80% Confidence




Bullish Case: Known: mean-reverting tape; today $85.5 within prior 78–88 band (April/May calibration, >20% rally not materialized). Inferred from DCI IV surface: center strikes 80–95 have lower IV (~25–35) vs far downside wings (red), and from DCI return surface: likelihood concentrates around modest +5–15% returns. Uncertain: next earnings/guidance and late-June macro. If IV compresses and DCI holds 83–86, 90–93 upside is plausible.




Bearish Case: Known: put flow > calls; DCI -2.9% vs 60d; 70–75 downside thesis not realized yet. Inferred from SPY IV surface: pronounced put-skew persists into ~1–3 months; DCI IV surface prices hot downside wings, implying tail hedging. DCI return surface shows lower likelihood for large negatives but not zero. Uncertain: whether an earnings/guidance miss breaks 82. If it does, -10%+ becomes more likely than reversion.




Potential Outcomes:
  1. 35% +0–8%: oracle bull spreads only if DCI holds 83–86 and DCI IV 80–95 ~25–35 (SPY IV<20).
  2. 15% +10–20%: reclaim 90; call IV rises and SPY calms.
  3. 30% -3–15%: mean-reversion fails; DCI <82 as SPY put-skew persists.
  4. 20% -15%+: credit/macro shock; DCI far-put IV stays “red”.
