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 WBA 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 4, 2019
End date: May 22, 2020

a = 7.8510

b = -0.0023

s = 0.0393

Annual growth rate:

Exp(365 × b) – 1
= Exp(365 × -0.0023) – 1
= -57.44%

Price channel spread:

Exp(4 × s) – 1
= Exp(4 × 0.0393) – 1
= 17.04%

Top border of price channel:

Exp(Y1,088)
= Exp(a + b × X1,088 + 2 × s)
= Exp(a + b × 1,578 + 2 × s)
= Exp(7.8510 + -0.0023 × 1,578 + 2 × 0.0393)
= Exp(4.2365)
= $69.17

Bottom border of price channel:

Exp(Y1,088)
= Exp(a + b × X1,088 – 2 × s)
= Exp(a + b × 1,578 – 2 × s)
