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 JJSF 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 13, 2024
End date: July 11, 2025

a = 7.3016

b = -0.0014

s = 0.0544

Annual growth rate:

Exp(365 × b) – 1
= Exp(365 × -0.0014) – 1
= -40.44%

Price channel spread:

Exp(4 × s) – 1
= Exp(4 × 0.0544) – 1
= 24.32%

Top border of price channel:

Exp(Y1,027)
= Exp(a + b × X1,027 + 2 × s)
= Exp(a + b × 1,491 + 2 × s)
= Exp(7.3016 + -0.0014 × 1,491 + 2 × 0.0544)
= Exp(5.2939)
= $199.13

Bottom border of price channel:

Exp(Y1,027)
= Exp(a + b × X1,027 – 2 × s)
= Exp(a + b × 1,491 – 2 × s)
= Exp(7.3016 + -0.0014 × 1,491 – 2 × 0.0544)
= Exp(5.0763)
= $160.18

= Exp(a + b × X1,254 + 2 × s)
= Exp(a + b × 1,823 + 2 × s)
= Exp(7.3016 + -0.0014 × 1,823 + 2 × 0.0544)
= Exp(4.8227)
= $124.30

Bottom border of price channel:

Exp(Y1,254)
= Exp(a + b × X1,254 – 2 × s)
= Exp(a + b × 1,823 – 2 × s)

= Exp(4.6050)
= $99.98
