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

End date: February 11, 2025
a = 3.2358
b = 0.0012
s = 0.0549
Annual growth rate:
Exp(365 × b) – 1
= Exp(365 × 0.0012) – 1
= 55.30%
Price channel spread:
Exp(4 × s) – 1
= Exp(4 × 0.0549) – 1
= 24.56%

Top border of price channel:
Exp(Y720)
= Exp(a + b × X720 + 2 × s)
= Exp(a + b × 1,044 + 2 × s)
= Exp(3.2358 + 0.0012 × 1,044 + 2 × 0.0549)
= Exp(4.6047)
= $99.96
Bottom border of price channel:
Exp(Y720)
= Exp(a + b × X720 – 2 × s)
= Exp(a + b × 1,044 – 2 × s)
= Exp(3.2358 + 0.0012 × 1,044 – 2 × 0.0549)
= Exp(4.3851)
= $80.25
