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 SO 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 18, 2024
End date: October 28, 2024

a = 2.1108

b = 0.0014

s = 0.0244

Annual growth rate:

Exp(365 × b) – 1
= Exp(365 × 0.0014) – 1
= 63.78%

Price channel spread:

Exp(4 × s) – 1
= Exp(4 × 0.0244) – 1
= 10.24%

January 18, 2024 calculations

Top border of price channel:

Exp(Y1,037)
= Exp(a + b × X1,037 + 2 × s)
= Exp(a + b × 1,507 + 2 × s)
= Exp(2.1108 + 0.0014 × 1,507 + 2 × 0.0244)
= Exp(4.1965)
= $66.46

Bottom border of price channel:

Exp(Y1,037)
= Exp(a + b × X1,037 – 2 × s)
= Exp(a + b × 1,507 – 2 × s)
= Exp(2.1108 + 0.0014 × 1,507 – 2 × 0.0244)
= Exp(4.0991)
= $60.28

October 28, 2024 calculations

Top border of price channel:

Exp(Y1,233)
= Exp(a + b × X1,233 + 2 × s)
= Exp(a + b × 1,791 + 2 × s)
= Exp(2.1108 + 0.0014 × 1,791 + 2 × 0.0244)
= Exp(4.5804)
= $97.56

Bottom border of price channel:

Exp(Y1,233)
= Exp(a + b × X1,233 – 2 × s)
= Exp(a + b × 1,791 – 2 × s)
= Exp(2.1108 + 0.0014 × 1,791 – 2 × 0.0244)
= Exp(4.4830)
= $88.50

a = 3.9260

b = 0.0003

s = 0.0198

Annual growth rate:

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