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 SLB 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: July 11, 2023
End date: October 22, 2025

a = 4.6716

b = -0.0007

s = 0.0529

Annual growth rate:

Exp(365 × b) – 1
= Exp(365 × -0.0007) – 1
= -21.21%

Price channel spread:

Exp(4 × s) – 1
= Exp(4 × 0.0529) – 1
= 23.55%

Top border of price channel:

Exp(Y675)
= Exp(a + b × X675 + 2 × s)
= Exp(a + b × 984 + 2 × s)
= Exp(4.6716 + -0.0007 × 984 + 2 × 0.0529)
= Exp(4.1346)
= $62.47

Bottom border of price channel:

Exp(Y675)
= Exp(a + b × X675 – 2 × s)
= Exp(a + b × 984 – 2 × s)
= Exp(4.6716 + -0.0007 × 984 – 2 × 0.0529)
= Exp(3.9232)
= $50.56

Top border of price channel:

Exp(Y1,249)
= Exp(a + b × X1,249 + 2 × s)
= Exp(a + b × 1,818 + 2 × s)
= Exp(4.6716 + -0.0007 × 1,818 + 2 × 0.0529)
= Exp(3.5899)
= $36.23

Bottom border of price channel:

Exp(Y1,249)
= Exp(a + b × X1,249 – 2 × s)
= Exp(a + b × 1,818 – 2 × s)
= Exp(4.6716 + -0.0007 × 1,818 – 2 × 0.0529)
= Exp(3.3784)
= $29.33
