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

a = 4.9230

b = -0.0005

s = 0.0828

Annual growth rate:

Exp(365 × b) – 1
= Exp(365 × -0.0005) – 1
= -17.95%

Price channel spread:

Exp(4 × s) – 1
= Exp(4 × 0.0828) – 1
= 39.29%

Top border of price channel:

Exp(Y427)
= Exp(a + b × X427 + 2 × s)
= Exp(a + b × 617 + 2 × s)
= Exp(4.9230 + -0.0005 × 617 + 2 × 0.0828)
= Exp(4.7543)
= $116.08

Bottom border of price channel:

Exp(Y427)
= Exp(a + b × X427 – 2 × s)
= Exp(a + b × 617 – 2 × s)
= Exp(4.9230 + -0.0005 × 617 – 2 × 0.0828)
= Exp(4.4229)
= $83.34
