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: January 14, 2026
a = 2.9474
b = 0.0005
s = 0.0198
Annual growth rate:
Exp(365 × b) – 1
= Exp(365 × 0.0005) – 1
= 18.13%
Price channel spread:
Exp(4 × s) – 1
= Exp(4 × 0.0198) – 1
= 8.24%

Top border of price channel:
Exp(Y209)
= Exp(a + b × X209 + 2 × s)
= Exp(a + b × 307 + 2 × s)
= Exp(2.9474 + 0.0005 × 307 + 2 × 0.0198)
= Exp(3.1272)
= $22.81
Bottom border of price channel:
Exp(Y209)
= Exp(a + b × X209 – 2 × s)
= Exp(a + b × 307 – 2 × s)
= Exp(2.9474 + 0.0005 × 307 – 2 × 0.0198)
= Exp(3.0480)
= $21.07

Top border of price channel:
Exp(Y325)
= Exp(a + b × X325 + 2 × s)
= Exp(a + b × 475 + 2 × s)
= Exp(2.9474 + 0.0005 × 475 + 2 × 0.0198)
= Exp(3.2038)
= $24.63
Bottom border of price channel:
Exp(Y325)
= Exp(a + b × X325 – 2 × s)
= Exp(a + b × 475 – 2 × s)
= Exp(2.9474 + 0.0005 × 475 – 2 × 0.0198)
= Exp(3.1246)
= $22.75
