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 MMC 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: February 24, 2025
End date: January 7, 2026

a = 6.8349

b = -0.0009

s = 0.0295

Annual growth rate:

Exp(365 × b) – 1
= Exp(365 × -0.0009) – 1
= -28.06%

Price channel spread:

Exp(4 × s) – 1
= Exp(4 × 0.0295) – 1
= 12.50%

Top border of price channel:

Exp(Y1,035)
= Exp(a + b × X1,035 + 2 × s)
= Exp(a + b × 1,508 + 2 × s)
= Exp(6.8349 + -0.0009 × 1,508 + 2 × 0.0295)
= Exp(5.5333)
= $252.97

Bottom border of price channel:

Exp(Y1,035)
= Exp(a + b × X1,035 – 2 × s)
= Exp(a + b × 1,508 – 2 × s)
= Exp(6.8349 + -0.0009 × 1,508 – 2 × 0.0295)
= Exp(5.4155)
= $224.86

= Exp(5.2473)
= $190.05

Bottom border of price channel:

Exp(Y1,254)
