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: February 8, 2021
End date: February 21, 2024

a = 4.9159

b = -0.0006

s = 0.1046

Annual growth rate:

Exp(365 × b) – 1
= Exp(365 × -0.0006) – 1
= -18.26%

Price channel spread:

Exp(4 × s) – 1
= Exp(4 × 0.1046) – 1
= 51.93%

February 8, 2021 calculations

Top border of price channel:

Exp(Y304)
= Exp(a + b × X304 + 2 × s)
= Exp(a + b × 445 + 2 × s)
= Exp(4.9159 + -0.0006 × 445 + 2 × 0.1046)
= Exp(4.8792)
= $131.52

Bottom border of price channel:

Exp(Y304)
= Exp(a + b × X304 – 2 × s)
= Exp(a + b × 445 – 2 × s)
= Exp(4.9159 + -0.0006 × 445 – 2 × 0.1046)
= Exp(4.4609)
= $86.57

February 21, 2024 calculations

Top border of price channel:

Exp(Y1,067)
= Exp(a + b × X1,067 + 2 × s)
= Exp(a + b × 1,553 + 2 × s)
= Exp(4.9159 + -0.0006 × 1,553 + 2 × 0.1046)
= Exp(4.2669)
= $71.30

Bottom border of price channel:

Exp(Y1,067)
= Exp(a + b × X1,067 – 2 × s)
= Exp(a + b × 1,553 – 2 × s)
= Exp(4.9159 + -0.0006 × 1,553 – 2 × 0.1046)
= Exp(3.8487)
= $46.93

a = 4.0460

b = 0.0002

s = 0.1338

Annual growth rate:

Exp(365 × b) – 1
= Exp(365 × 0.0002) – 1
