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 KALU 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 22, 2025
End date: January 16, 2026
a = -3.9697
b = 0.0048
s = 0.0382
Annual growth rate:
Exp(365 × b) – 1
= Exp(365 × 0.0048) – 1
= 484.53%
Price channel spread:
Exp(4 × s) – 1
= Exp(4 × 0.0382) – 1
= 16.53%

Top border of price channel:
Exp(Y1,174)
= Exp(a + b × X1,174 + 2 × s)
= Exp(a + b × 1,707 + 2 × s)
= Exp(-3.9697 + 0.0048 × 1,707 + 2 × 0.0382)
= Exp(4.3641)
= $78.58
Bottom border of price channel:
Exp(Y1,174)
= Exp(a + b × X1,174 – 2 × s)
= Exp(a + b × 1,707 – 2 × s)
= Exp(-3.9697 + 0.0048 × 1,707 – 2 × 0.0382)
= Exp(4.2111)
= $67.43
