Lo spread — il grafico chiave. La linea verde misura la “distanza” tra le due azioni: ln(EXR) − β·ln(PSA). La riga orizzontale al centro e’ il suo valore medio (μ), la banda grigia l’oscillazione normale (±σ e ±2σ). Come leggerlo: finche’ la linea resta nella banda le due azioni sono in equilibrio. Quando esce in alto, EXR e’ diventata cara rispetto a PSA; quando esce in basso, il contrario. Piu’ e’ lontana dal centro (z elevato), piu’ ci si aspetta che rientri: e’ li’ che nasce il segnale di pair trading.
Setup contrarian: RSI(14) < 30 (ipervenduto) o > 70 (ipercomprato) sullo spread daily, in concomitanza con volume aggregato min(VEXR, VPSA) < SMA(20). Volume basso in fase estrema = forza del movimento in esaurimento ⇒ mean reversion più probabile. Le zone gialle sul grafico evidenziano i giorni triggered.
Setup volatilità: %b > 1 (spread sopra banda superiore ⇒ short spread) o %b < 0 (sotto banda inferiore ⇒ long spread), in concomitanza con BandWidth in pendenza piatta o negativa su 5 giorni (volatilità non in espansione ⇒ movimento esaurito). Bande di Bollinger SMA(20) ± 2σ rolling. Le zone gialle evidenziano i giorni triggered.
