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 PSX 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 31, 2024
End date: April 3, 2025

a = 5.7427

b = -0.0005

s = 0.0508

Annual growth rate:

Exp(365 × b) – 1
= Exp(365 × -0.0005) – 1
= -17.70%

Price channel spread:

Exp(4 × s) – 1
= Exp(4 × 0.0508) – 1
= 22.54%

Top border of price channel:

Exp(Y961)
= Exp(a + b × X961 + 2 × s)
= Exp(a + b × 1,395 + 2 × s)
= Exp(5.7427 + -0.0005 × 1,395 + 2 × 0.0508)
= Exp(5.1000)
= $164.02

Bottom border of price channel:

Exp(Y961)
= Exp(a + b × X961 – 2 × s)
= Exp(a + b × 1,395 – 2 × s)
= Exp(5.7427 + -0.0005 × 1,395 – 2 × 0.0508)
= Exp(4.8968)
= $133.85
