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 6, 2025
End date: January 28, 2025

a = 2.7659

b = 0.0035

s = 0.0138

Annual growth rate:

Exp(365 × b) – 1
= Exp(365 × 0.0035) – 1
= 263.64%

Price channel spread:

Exp(4 × s) – 1
= Exp(4 × 0.0138) – 1
= 5.68%

Top border of price channel:

Exp(Y69)
= Exp(a + b × X69 + 2 × s)
= Exp(a + b × 102 + 2 × s)
= Exp(2.7659 + 0.0035 × 102 + 2 × 0.0138)
= Exp(3.1543)
= $23.44

Bottom border of price channel:

Exp(Y69)
= Exp(a + b × X69 – 2 × s)
= Exp(a + b × 102 – 2 × s)
= Exp(2.7659 + 0.0035 × 102 – 2 × 0.0138)
= Exp(3.0990)
= $22.18

Top border of price channel:

Exp(Y83)
= Exp(a + b × X83 + 2 × s)
= Exp(a + b × 124 + 2 × s)
= Exp(2.7659 + 0.0035 × 124 + 2 × 0.0138)
= Exp(3.2321)
= $25.33

Bottom border of price channel:

Exp(Y83)
= Exp(a + b × X83 – 2 × s)
= Exp(a + b × 124 – 2 × s)
= Exp(2.7659 + 0.0035 × 124 – 2 × 0.0138)
= Exp(3.1769)
= $23.97

Secondary Trend

Start date: January 13, 2025
End date: January 28, 2025

a = 2.6650

b = 0.0044

s = 0.0151

Annual growth rate:

Exp(365 × b) – 1
= Exp(365 × 0.0044) – 1
= 396.60%

Price channel spread:

Exp(4 × s) – 1
= Exp(4 × 0.0151) – 1
= 6.22%

Top border of price channel:

Exp(Y73)
= Exp(a + b × X73 + 2 × s)
= Exp(a + b × 109 + 2 × s)
= Exp(2.6650 + 0.0044 × 109 + 2 × 0.0151)
= Exp(3.1737)
= $23.90

Bottom border of price channel:

Exp(Y73)
= Exp(a + b × X73 – 2 × s)
