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 BWA 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 26, 2023
End date: September 18, 2024

a = 4.3793

b = -0.0005

s = 0.0655

Annual growth rate:

Exp(365 × b) – 1
= Exp(365 × -0.0005) – 1
= -17.69%

Price channel spread:

Exp(4 × s) – 1
= Exp(4 × 0.0655) – 1
= 29.96%

January 26, 2023 calculations

Top border of price channel:

Exp(Y799)
= Exp(a + b × X799 + 2 × s)
= Exp(a + b × 1,162 + 2 × s)
= Exp(4.3793 + -0.0005 × 1,162 + 2 × 0.0655)
= Exp(3.8905)
= $48.94

Bottom border of price channel:

Exp(Y799)
= Exp(a + b × X799 – 2 × s)
= Exp(a + b × 1,162 – 2 × s)
= Exp(4.3793 + -0.0005 × 1,162 – 2 × 0.0655)
= Exp(3.6285)
= $37.66

September 18, 2024 calculations

Top border of price channel:

Exp(Y1,212)
= Exp(a + b × X1,212 + 2 × s)
= Exp(a + b × 1,763 + 2 × s)
= Exp(4.3793 + -0.0005 × 1,763 + 2 × 0.0655)
= Exp(3.5700)
= $35.52

Bottom border of price channel:

Exp(Y1,212)
= Exp(a + b × X1,212 – 2 × s)
= Exp(a + b × 1,763 – 2 × s)
= Exp(4.3793 + -0.0005 × 1,763 – 2 × 0.0655)
= Exp(3.3079)
= $27.33

a = 3.3937

b = 0.0001

s = 0.0461

Annual growth rate:

Exp(365 × b) – 1
= Exp(365 × 0.0001) – 1
= 2.63%

Price channel spread:

Exp(4 × s) – 1
