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 AIR 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: March 28, 2025
End date: July 31, 2025

a = -1.9048

b = 0.0036

s = 0.0426

Annual growth rate:

Exp(365 × b) – 1
= Exp(365 × 0.0036) – 1
= 276.05%

Price channel spread:

Exp(4 × s) – 1
= Exp(4 × 0.0426) – 1
= 18.60%

March 28, 2025 calculations

Top border of price channel:

Exp(Y1,103)
= Exp(a + b × X1,103 + 2 × s)
= Exp(a + b × 1,605 + 2 × s)
= Exp(-1.9048 + 0.0036 × 1,605 + 2 × 0.0426)
= Exp(4.0049)
= $54.86

Bottom border of price channel:

Exp(Y1,103)
= Exp(a + b × X1,103 – 2 × s)
= Exp(a + b × 1,605 – 2 × s)
= Exp(-1.9048 + 0.0036 × 1,605 – 2 × 0.0426)
= Exp(3.8343)
= $46.26

July 31, 2025 calculations

Top border of price channel:

Exp(Y1,188)
= Exp(a + b × X1,188 + 2 × s)
= Exp(a + b × 1,730 + 2 × s)
= Exp(-1.9048 + 0.0036 × 1,730 + 2 × 0.0426)
= Exp(4.4585)
= $86.36

Bottom border of price channel:

Exp(Y1,188)
= Exp(a + b × X1,188 – 2 × s)
= Exp(a + b × 1,730 – 2 × s)
= Exp(-1.9048 + 0.0036 × 1,730 – 2 × 0.0426)
= Exp(4.2879)
= $72.81
