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 CVS 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: December 10, 2021
End date: November 19, 2024

a = 4.9882

b = -0.0005

s = 0.0796

Annual growth rate:

Exp(365 × b) – 1
= Exp(365 × -0.0005) – 1
= -17.43%

Price channel spread:

Exp(4 × s) – 1
= Exp(4 × 0.0796) – 1
= 37.47%

Top border of price channel:

Exp(Y518)
= Exp(a + b × X518 + 2 × s)
= Exp(a + b × 751 + 2 × s)
= Exp(4.9882 + -0.0005 × 751 + 2 × 0.0796)
= Exp(4.7533)
= $115.97

Bottom border of price channel:

Exp(Y518)
= Exp(a + b × X518 – 2 × s)
= Exp(a + b × 751 – 2 × s)
= Exp(4.9882 + -0.0005 × 751 – 2 × 0.0796)
= Exp(4.4351)
= $84.36
