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 BLFS 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: August 9, 2023
End date: February 21, 2025

a = 0.4681

b = 0.0017

s = 0.0995

Annual growth rate:

Exp(365 × b) – 1
= Exp(365 × 0.0017) – 1
= 84.17%

Price channel spread:

Exp(4 × s) – 1
= Exp(4 × 0.0995) – 1
= 48.88%

August 9, 2023 calculations

Top border of price channel:

Exp(Y825)
= Exp(a + b × X825 + 2 × s)
= Exp(a + b × 1,197 + 2 × s)
= Exp(0.4681 + 0.0017 × 1,197 + 2 × 0.0995)
= Exp(2.6698)
= $14.44

Bottom border of price channel:

Exp(Y825)
= Exp(a + b × X825 – 2 × s)
= Exp(a + b × 1,197 – 2 × s)
= Exp(0.4681 + 0.0017 × 1,197 – 2 × 0.0995)
= Exp(2.2719)
= $9.70

Top border of price channel:

Exp(Y1,210)
= Exp(a + b × X1,210 + 2 × s)
= Exp(a + b × 1,759 + 2 × s)
= Exp(0.4681 + 0.0017 × 1,759 + 2 × 0.0995)
= Exp(3.6101)
= $36.97

Bottom border of price channel:

Exp(Y1,210)
= Exp(a + b × X1,210 – 2 × s)
= Exp(a + b × 1,759 – 2 × s)
= Exp(0.4681 + 0.0017 × 1,759 – 2 × 0.0995)
= Exp(3.2122)
= $24.83
