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 AEE 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: January 17, 2024
End date: April 28, 2025
a = 2.8137
b = 0.0010
s = 0.0348
Annual growth rate:
Exp(365 × b) – 1
= Exp(365 × 0.0010) – 1
= 43.68%
Price channel spread:
Exp(4 × s) – 1
= Exp(4 × 0.0348) – 1
= 14.94%

Top border of price channel:
Exp(Y935)
= Exp(a + b × X935 + 2 × s)
= Exp(a + b × 1,358 + 2 × s)
= Exp(2.8137 + 0.0010 × 1,358 + 2 × 0.0348)
= Exp(4.2318)
= $68.84
Bottom border of price channel:
Exp(Y935)
= Exp(a + b × X935 – 2 × s)
= Exp(a + b × 1,358 – 2 × s)
= Exp(2.8137 + 0.0010 × 1,358 – 2 × 0.0348)
= Exp(4.0925)
= $59.89
