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 CURB 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 30, 2025
End date: December 5, 2025
a = 2.8849
b = 0.0006
s = 0.0192
Annual growth rate:
Exp(365 × b) – 1
= Exp(365 × 0.0006) – 1
= 26.02%
Price channel spread:
Exp(4 × s) – 1
= Exp(4 × 0.0192) – 1
= 7.97%

Top border of price channel:
Exp(Y209)
= Exp(a + b × X209 + 2 × s)
= Exp(a + b × 307 + 2 × s)
= Exp(2.8849 + 0.0006 × 307 + 2 × 0.0192)
= Exp(3.1178)
= $22.60
Bottom border of price channel:
Exp(Y209)
= Exp(a + b × X209 – 2 × s)
= Exp(a + b × 307 – 2 × s)
= Exp(2.8849 + 0.0006 × 307 – 2 × 0.0192)
= Exp(3.0411)
= $20.93

Top border of price channel:
Exp(Y299)
= Exp(a + b × X299 + 2 × s)
= Exp(a + b × 435 + 2 × s)
= Exp(2.8849 + 0.0006 × 435 + 2 × 0.0192)
= Exp(3.1989)
= $24.51
Bottom border of price channel:
Exp(Y299)
= Exp(a + b × X299 – 2 × s)
= Exp(a + b × 435 – 2 × s)
= Exp(2.8849 + 0.0006 × 435 – 2 × 0.0192)
= Exp(3.1222)
= $22.70
