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 PFE 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

Start date: November 17, 2021
End date: July 11, 2024
a = 4.3724
b = -0.0007
s = 0.0710
Annual growth rate:
Exp(365 × b) – 1
= Exp(365 × -0.0007) – 1
= -23.74%
Price channel spread:
Exp(4 × s) – 1
= Exp(4 × 0.0710) – 1
= 32.86%

Exp(Y412)
= Exp(a + b × X412 + 2 × s)
= Exp(a + b × 595 + 2 × s)
= Exp(4.3724 + -0.0007 × 595 + 2 × 0.0710)
= Exp(4.0726)
= $58.71
Bottom border of price channel:
Exp(Y412)
= Exp(a + b × X412 – 2 × s)
= Exp(a + b × 595 – 2 × s)
= Exp(4.3724 + -0.0007 × 595 – 2 × 0.0710)
= Exp(3.7885)
= $44.19
