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: February 18, 2026
a = 2.8834
b = 0.0006
s = 0.0251
Annual growth rate:
Exp(365 × b) – 1
= Exp(365 × 0.0006) – 1
= 25.83%
Price channel spread:
Exp(4 × s) – 1
= Exp(4 × 0.0251) – 1
= 10.54%

Top border of price channel:
Exp(Y209)
= Exp(a + b × X209 + 2 × s)
= Exp(a + b × 307 + 2 × s)
= Exp(2.8834 + 0.0006 × 307 + 2 × 0.0251)
= Exp(3.1268)
= $22.80
Bottom border of price channel:
Exp(Y209)
= Exp(a + b × X209 – 2 × s)
= Exp(a + b × 307 – 2 × s)
= Exp(2.8834 + 0.0006 × 307 – 2 × 0.0251)
= Exp(3.0266)
= $20.63

Top border of price channel:
Exp(Y348)
= Exp(a + b × X348 + 2 × s)
= Exp(a + b × 510 + 2 × s)
= Exp(2.8834 + 0.0006 × 510 + 2 × 0.0251)
= Exp(3.2546)
= $25.91
Bottom border of price channel:
Exp(Y348)
= Exp(a + b × X348 – 2 × s)
= Exp(a + b × 510 – 2 × s)
= Exp(2.8834 + 0.0006 × 510 – 2 × 0.0251)
= Exp(3.1544)
= $23.44
