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 18, 2024
End date: March 31, 2025

a = 2.7446

b = 0.0010

s = 0.0346

Annual growth rate:

Exp(365 × b) – 1
= Exp(365 × 0.0010) – 1
= 45.09%

Price channel spread:

Exp(4 × s) – 1
= Exp(4 × 0.0346) – 1
= 14.84%

Top border of price channel:

Exp(Y955)
= Exp(a + b × X955 + 2 × s)
= Exp(a + b × 1,387 + 2 × s)
= Exp(2.7446 + 0.0010 × 1,387 + 2 × 0.0346)
= Exp(4.2280)
= $68.58

Bottom border of price channel:

Exp(Y955)
= Exp(a + b × X955 – 2 × s)
= Exp(a + b × 1,387 – 2 × s)
= Exp(2.7446 + 0.0010 × 1,387 – 2 × 0.0346)
= Exp(4.0896)
= $59.72
