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 AON 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: April 26, 2024
End date: December 6, 2024

a = 3.1810

b = 0.0016

s = 0.0249

Annual growth rate:

Exp(365 × b) – 1
= Exp(365 × 0.0016) – 1
= 81.40%

Price channel spread:

Exp(4 × s) – 1
= Exp(4 × 0.0249) – 1
= 10.48%

Top border of price channel:

Exp(Y1,022)
= Exp(a + b × X1,022 + 2 × s)
= Exp(a + b × 1,484 + 2 × s)
= Exp(3.1810 + 0.0016 × 1,484 + 2 × 0.0249)
= Exp(5.6521)
= $284.90

Bottom border of price channel:

Exp(Y1,022)
= Exp(a + b × X1,022 – 2 × s)
= Exp(a + b × 1,484 – 2 × s)
= Exp(3.1810 + 0.0016 × 1,484 – 2 × 0.0249)
= Exp(5.5525)
= $257.89

December 6, 2024 calculations

Top border of price channel:

Exp(Y1,177)
= Exp(a + b × X1,177 + 2 × s)
= Exp(a + b × 1,708 + 2 × s)
= Exp(3.1810 + 0.0016 × 1,708 + 2 × 0.0249)
= Exp(6.0176)
= $410.60

Bottom border of price channel:

Exp(Y1,177)
= Exp(a + b × X1,177 – 2 × s)
= Exp(a + b × 1,708 – 2 × s)
= Exp(3.1810 + 0.0016 × 1,708 – 2 × 0.0249)
= Exp(5.9180)
= $371.67
