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 2, 2025
End date: February 18, 2026

a = -2.7809

b = 0.0043

s = 0.0439

Annual growth rate:

Exp(365 × b) – 1
= Exp(365 × 0.0043) – 1
= 377.15%

Price channel spread:

Exp(4 × s) – 1
= Exp(4 × 0.0439) – 1
= 19.20%

Top border of price channel:

Exp(Y1,127)
= Exp(a + b × X1,127 + 2 × s)
= Exp(a + b × 1,639 + 2 × s)
= Exp(-2.7809 + 0.0043 × 1,639 + 2 × 0.0439)
= Exp(4.3239)
= $75.48

Bottom border of price channel:

Exp(Y1,127)
= Exp(a + b × X1,127 – 2 × s)
= Exp(a + b × 1,639 – 2 × s)
= Exp(-2.7809 + 0.0043 × 1,639 – 2 × 0.0439)
= Exp(4.1483)
= $63.33

February 18, 2026 calculations

Top border of price channel:

Exp(Y1,243)
= Exp(a + b × X1,243 + 2 × s)
= Exp(a + b × 1,808 + 2 × s)
= Exp(-2.7809 + 0.0043 × 1,808 + 2 × 0.0439)
= Exp(5.0475)
= $155.63

Bottom border of price channel:

Exp(Y1,243)
= Exp(a + b × X1,243 – 2 × s)
= Exp(a + b × 1,808 – 2 × s)
= Exp(-2.7809 + 0.0043 × 1,808 – 2 × 0.0439)
= Exp(4.8719)
= $130.56
