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
Primary Trend
Start date: November 1, 2022
End date: April 26, 2024
a = 5.3293
b = -0.0012
s = 0.0411
Annual growth rate:
Exp(365 × b) – 1
= Exp(365 × -0.0012) – 1
= -34.35%
Price channel spread:
Exp(4 × s) – 1
= Exp(4 × 0.0411) – 1
= 17.88%

Exp(Y886)
= Exp(a + b × X886 + 2 × s)
= Exp(a + b × 1,282 + 2 × s)
= Exp(5.3293 + -0.0012 × 1,282 + 2 × 0.0411)
= Exp(3.9332)
= $51.07
Bottom border of price channel:
Exp(Y886)
= Exp(a + b × X886 – 2 × s)
= Exp(a + b × 1,282 – 2 × s)
= Exp(5.3293 + -0.0012 × 1,282 – 2 × 0.0411)
= Exp(3.7687)
= $43.32
