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 ALE 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: June 27, 2023
End date: November 28, 2025

a = 3.6013

b = 0.0003

s = 0.0339

Annual growth rate:

Exp(365 × b) – 1
= Exp(365 × 0.0003) – 1
= 13.51%

Price channel spread:

Exp(4 × s) – 1
= Exp(4 × 0.0339) – 1
= 14.52%

Top border of price channel:

Exp(Y645)
= Exp(a + b × X645 + 2 × s)
= Exp(a + b × 938 + 2 × s)
= Exp(3.6013 + 0.0003 × 938 + 2 × 0.0339)
= Exp(3.9948)
= $54.31

Bottom border of price channel:

Exp(Y645)
= Exp(a + b × X645 – 2 × s)
= Exp(a + b × 938 – 2 × s)
= Exp(3.6013 + 0.0003 × 938 – 2 × 0.0339)
= Exp(3.8591)
= $47.42
