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 APH 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: February 21, 2023
End date: January 24, 2025

a = 2.3776

b = 0.0011

s = 0.0615

Annual growth rate:

Exp(365 × b) – 1
= Exp(365 × 0.0011) – 1
= 50.22%

Price channel spread:

Exp(4 × s) – 1
= Exp(4 × 0.0615) – 1
= 27.87%

February 21, 2023 calculations

Top border of price channel:

Exp(Y725)
= Exp(a + b × X725 + 2 × s)
= Exp(a + b × 1,054 + 2 × s)
= Exp(2.3776 + 0.0011 × 1,054 + 2 × 0.0615)
= Exp(3.6756)
= $39.47

Bottom border of price channel:

Exp(Y725)
= Exp(a + b × X725 – 2 × s)
= Exp(a + b × 1,054 – 2 × s)
= Exp(2.3776 + 0.0011 × 1,054 – 2 × 0.0615)
= Exp(3.4298)
= $30.87

January 24, 2025 calculations

Top border of price channel:

Exp(Y1,208)
= Exp(a + b × X1,208 + 2 × s)
= Exp(a + b × 1,757 + 2 × s)
= Exp(2.3776 + 0.0011 × 1,757 + 2 × 0.0615)
= Exp(4.4594)
= $86.44

Bottom border of price channel:

Exp(Y1,208)
= Exp(a + b × X1,208 – 2 × s)
= Exp(a + b × 1,757 – 2 × s)
= Exp(2.3776 + 0.0011 × 1,757 – 2 × 0.0615)
= Exp(4.2136)
= $67.60

a = 3.8574

b = 0.0002

s = 0.0529

Annual growth rate:

Exp(365 × b) – 1
= Exp(365 × 0.0002) – 1
= 7.94%
