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 MUSA 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 18, 2024
End date: December 11, 2025

a = 7.2652

b = -0.0007

s = 0.0571

Annual growth rate:

Exp(365 × b) – 1
= Exp(365 × -0.0007) – 1
= -23.63%

Price channel spread:

Exp(4 × s) – 1
= Exp(4 × 0.0571) – 1
= 25.66%

Top border of price channel:

Exp(Y902)
= Exp(a + b × X902 + 2 × s)
= Exp(a + b × 1,312 + 2 × s)
= Exp(7.2652 + -0.0007 × 1,312 + 2 × 0.0571)
= Exp(6.4106)
= $608.25

Bottom border of price channel:

Exp(Y902)
= Exp(a + b × X902 – 2 × s)
= Exp(a + b × 1,312 – 2 × s)
= Exp(7.2652 + -0.0007 × 1,312 – 2 × 0.0571)
= Exp(6.1821)
= $484.03
