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 WHD 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: June 1, 2021
End date: July 11, 2024

a = 3.5931

b = 0.0002

s = 0.1320

Annual growth rate:

Exp(365 × b) – 1
= Exp(365 × 0.0002) – 1
= 7.13%

Price channel spread:

Exp(4 × s) – 1
= Exp(4 × 0.1320) – 1
= 69.56%

Top border of price channel:

Exp(Y292)
= Exp(a + b × X292 + 2 × s)
= Exp(a + b × 425 + 2 × s)
= Exp(3.5931 + 0.0002 × 425 + 2 × 0.1320)
= Exp(3.9373)
= $51.28

Bottom border of price channel:

Exp(Y292)
= Exp(a + b × X292 – 2 × s)
= Exp(a + b × 425 – 2 × s)
= Exp(3.5931 + 0.0002 × 425 – 2 × 0.1320)
= Exp(3.4093)
= $30.24

Top border of price channel:

Exp(Y1,074)
= Exp(a + b × X1,074 + 2 × s)
= Exp(a + b × 1,561 + 2 × s)
= Exp(3.5931 + 0.0002 × 1,561 + 2 × 0.1320)
= Exp(4.1517)
= $63.54

Bottom border of price channel:

Exp(Y1,074)
= Exp(a + b × X1,074 – 2 × s)
= Exp(a + b × 1,561 – 2 × s)
= Exp(3.5931 + 0.0002 × 1,561 – 2 × 0.1320)
= Exp(3.6236)
= $37.47

a = 2.8791

b = 0.0007

s = 0.0951

Annual growth rate:

Exp(365 × b) – 1
= Exp(365 × 0.0007) – 1
= 29.77%

Price channel spread:

Top border of price channel:

Exp(Y739)
= Exp(a + b × X739 + 2 × s)
= Exp(a + b × 1,072 + 2 × s)
= Exp(2.8791 + 0.0007 × 1,072 + 2 × 0.0951)
= Exp(3.8348)
= $46.28

Bottom border of price channel:
