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 26, 2021
End date: July 11, 2024

a = 4.5261

b = -0.0008

s = 0.0699

Annual growth rate:

Exp(365 × b) – 1
= Exp(365 × -0.0008) – 1
= -23.98%

Price channel spread:

Exp(4 × s) – 1
= Exp(4 × 0.0699) – 1
= 32.26%

Top border of price channel:

Exp(Y519)
= Exp(a + b × X519 + 2 × s)
= Exp(a + b × 752 + 2 × s)
= Exp(4.5261 + -0.0008 × 752 + 2 × 0.0699)
= Exp(4.1011)
= $60.40

Bottom border of price channel:

Exp(Y519)
= Exp(a + b × X519 – 2 × s)
= Exp(a + b × 752 – 2 × s)
= Exp(4.5261 + -0.0008 × 752 – 2 × 0.0699)
= Exp(3.8215)
= $45.67
