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 HAL 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: July 31, 2023
End date: April 1, 2025

a = 4.6092

b = -0.0007

s = 0.0611

Annual growth rate:

Exp(365 × b) – 1
= Exp(365 × -0.0007) – 1
= -23.62%

Price channel spread:

Exp(4 × s) – 1
= Exp(4 × 0.0611) – 1
= 27.70%

Top border of price channel:

Exp(Y836)
= Exp(a + b × X836 + 2 × s)
= Exp(a + b × 1,215 + 2 × s)
= Exp(4.6092 + -0.0007 × 1,215 + 2 × 0.0611)
= Exp(3.8346)
= $46.27

Bottom border of price channel:

Exp(Y836)
= Exp(a + b × X836 – 2 × s)
= Exp(a + b × 1,215 – 2 × s)
= Exp(4.6092 + -0.0007 × 1,215 – 2 × 0.0611)
= Exp(3.5901)
= $36.24

Top border of price channel:

Exp(Y1,255)
= Exp(a + b × X1,255 + 2 × s)
= Exp(a + b × 1,825 + 2 × s)
= Exp(4.6092 + -0.0007 × 1,825 + 2 × 0.0611)
= Exp(3.3843)
= $29.50

Bottom border of price channel:

Exp(Y1,255)
= Exp(a + b × X1,255 – 2 × s)
= Exp(a + b × 1,825 – 2 × s)
= Exp(4.6092 + -0.0007 × 1,825 – 2 × 0.0611)
= Exp(3.1398)
= $23.10
