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: January 24, 2025
End date: April 29, 2025
a = 3.3225
b = -0.0009
s = 0.0217
Annual growth rate:
Exp(365 × b) – 1
= Exp(365 × -0.0009) – 1
= -28.22%
Price channel spread:
Exp(4 × s) – 1
= Exp(4 × 0.0217) – 1
= 9.06%

Top border of price channel:
Exp(Y81)
= Exp(a + b × X81 + 2 × s)
= Exp(a + b × 120 + 2 × s)
= Exp(3.3225 + -0.0009 × 120 + 2 × 0.0217)
= Exp(3.2569)
= $25.97
Bottom border of price channel:
Exp(Y81)
= Exp(a + b × X81 – 2 × s)
= Exp(a + b × 120 – 2 × s)
= Exp(3.3225 + -0.0009 × 120 – 2 × 0.0217)
= Exp(3.1701)
= $23.81

Top border of price channel:
Exp(Y146)
= Exp(a + b × X146 + 2 × s)
= Exp(a + b × 215 + 2 × s)
= Exp(3.3225 + -0.0009 × 215 + 2 × 0.0217)
= Exp(3.1706)
= $23.82
Bottom border of price channel:
Exp(Y146)
= Exp(a + b × X146 – 2 × s)
= Exp(a + b × 215 – 2 × s)
= Exp(3.3225 + -0.0009 × 215 – 2 × 0.0217)
= Exp(3.0838)
= $21.84
