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: April 28, 2025
a = 4.7919
b = -0.0006
s = 0.0533
Annual growth rate:
Exp(365 × b) – 1
= Exp(365 × -0.0006) – 1
= -20.85%
Price channel spread:
Exp(4 × s) – 1
= Exp(4 × 0.0533) – 1
= 23.78%

Top border of price channel:
Exp(Y804)
= Exp(a + b × X804 + 2 × s)
= Exp(a + b × 1,168 + 2 × s)
= Exp(4.7919 + -0.0006 × 1,168 + 2 × 0.0533)
= Exp(4.1504)
= $63.46
Bottom border of price channel:
Exp(Y804)
= Exp(a + b × X804 – 2 × s)
= Exp(a + b × 1,168 – 2 × s)
= Exp(4.7919 + -0.0006 × 1,168 – 2 × 0.0533)
= Exp(3.9371)
= $51.27

Top border of price channel:
Exp(Y1,255)
= Exp(a + b × X1,255 + 2 × s)
= Exp(a + b × 1,825 + 2 × s)
= Exp(4.7919 + -0.0006 × 1,825 + 2 × 0.0533)
= Exp(3.7295)
= $41.66
Bottom border of price channel:
Exp(Y1,255)
= Exp(a + b × X1,255 – 2 × s)
= Exp(a + b × 1,825 – 2 × s)
= Exp(4.7919 + -0.0006 × 1,825 – 2 × 0.0533)
= Exp(3.5162)
= $33.66
