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 22, 2023
End date: October 29, 2025
a = 4.4942
b = -0.0003
s = 0.1045
Annual growth rate:
Exp(365 × b) – 1
= Exp(365 × -0.0003) – 1
= -9.93%
Price channel spread:
Exp(4 × s) – 1
= Exp(4 × 0.1045) – 1
= 51.91%

Top border of price channel:
Exp(Y770)
= Exp(a + b × X770 + 2 × s)
= Exp(a + b × 1,118 + 2 × s)
= Exp(4.4942 + -0.0003 × 1,118 + 2 × 0.1045)
= Exp(4.3828)
= $80.07
Bottom border of price channel:
Exp(Y770)
= Exp(a + b × X770 – 2 × s)
= Exp(a + b × 1,118 – 2 × s)
= Exp(4.4942 + -0.0003 × 1,118 – 2 × 0.1045)
= Exp(3.9647)
= $52.70
