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 WAB 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: March 15, 2023
End date: November 19, 2024

a = 3.0311

b = 0.0012

s = 0.0566

Annual growth rate:

Exp(365 × b) – 1
= Exp(365 × 0.0012) – 1
= 55.67%

Price channel spread:

Exp(4 × s) – 1
= Exp(4 × 0.0566) – 1
= 25.40%

Top border of price channel:

Exp(Y833)
= Exp(a + b × X833 + 2 × s)
= Exp(a + b × 1,211 + 2 × s)
= Exp(3.0311 + 0.0012 × 1,211 + 2 × 0.0566)
= Exp(4.6126)
= $100.75

Bottom border of price channel:

Exp(Y833)
= Exp(a + b × X833 – 2 × s)
= Exp(a + b × 1,211 – 2 × s)
= Exp(3.0311 + 0.0012 × 1,211 – 2 × 0.0566)
= Exp(4.3863)
= $80.34
