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%

January 24, 2025 calculations

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

a = 2.6676

b = 0.0022

s = 0.0153

Annual growth rate:

Exp(365 × b) – 1
= Exp(365 × 0.0022) – 1
= 127.23%

Price channel spread:

Exp(4 × s) – 1

Top border of price channel:

Exp(Y131)
= Exp(a + b × X131 + 2 × s)
= Exp(a + b × 193 + 2 × s)
= Exp(2.6676 + 0.0022 × 193 + 2 × 0.0153)
= Exp(3.1323)
= $22.93
