Linear Regression Model
Model equation:
Yi = α + β × Xi + εi
Top border of price channel:
Exp(Yi) = Exp(a + b × Xi + 2 × s)
Bottom border of price channel:
Exp(Yi) = Exp(a + b × Xi – 2 × s)
where:
i - observation number
Yi - natural logarithm of DFIN price
Xi - time index, 1 day interval
σ - standard deviation of εi
a - estimator of α
b - estimator of β
s - estimator of σ
Exp() - calculates the exponent of e
Primary Trend
Start date: November 24, 2023
End date: November 12, 2025
a = 4.5238
b = -0.0003
s = 0.1051
Annual growth rate:
Exp(365 × b) – 1
= Exp(365 × -0.0003) – 1
= -10.74%
Price channel spread:
Exp(4 × s) – 1
= Exp(4 × 0.1051) – 1
= 52.27%

Top border of price channel:
Exp(Y761)
= Exp(a + b × X761 + 2 × s)
= Exp(a + b × 1,106 + 2 × s)
= Exp(4.5238 + -0.0003 × 1,106 + 2 × 0.1051)
= Exp(4.3898)
= $80.63
Bottom border of price channel:
Exp(Y761)
= Exp(a + b × X761 – 2 × s)
= Exp(a + b × 1,106 – 2 × s)
= Exp(4.5238 + -0.0003 × 1,106 – 2 × 0.1051)
= Exp(3.9693)
= $52.95

Top border of price channel:
Exp(Y1,254)
= Exp(a + b × X1,254 + 2 × s)
= Exp(a + b × 1,825 + 2 × s)
= Exp(4.5238 + -0.0003 × 1,825 + 2 × 0.1051)
= Exp(4.1661)
= $64.46
Bottom border of price channel:
Exp(Y1,254)
= Exp(a + b × X1,254 – 2 × s)
= Exp(a + b × 1,825 – 2 × s)
= Exp(4.5238 + -0.0003 × 1,825 – 2 × 0.1051)
= Exp(3.7456)
= $42.33
