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 WEC 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: September 26, 2023
End date: December 1, 2025
a = 3.6673
b = 0.0006
s = 0.0457
Annual growth rate:
Exp(365 × b) – 1
= Exp(365 × 0.0006) – 1
= 25.57%
Price channel spread:
Exp(4 × s) – 1
= Exp(4 × 0.0457) – 1
= 20.08%

Top border of price channel:
Exp(Y639)
= Exp(a + b × X639 + 2 × s)
= Exp(a + b × 928 + 2 × s)
= Exp(3.6673 + 0.0006 × 928 + 2 × 0.0457)
= Exp(4.3378)
= $76.54
Bottom border of price channel:
Exp(Y639)
= Exp(a + b × X639 – 2 × s)
= Exp(a + b × 928 – 2 × s)
= Exp(3.6673 + 0.0006 × 928 – 2 × 0.0457)
= Exp(4.1548)
= $63.74

= Exp(4.8350)
= $125.84
Bottom border of price channel:
Exp(Y1,186)
= Exp(a + b × X1,186 – 2 × s)
= Exp(a + b × 1,725 – 2 × s)
= Exp(3.6673 + 0.0006 × 1,725 – 2 × 0.0457)
= Exp(4.6520)
