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 HELE 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: December 13, 2023
End date: July 3, 2025

a = 8.1451

b = -0.0026

s = 0.1892

Annual growth rate:

Exp(365 × b) – 1
= Exp(365 × -0.0026) – 1
= -60.75%

Price channel spread:

Exp(4 × s) – 1
= Exp(4 × 0.1892) – 1
= 113.18%

Top border of price channel:

Exp(Y867)
= Exp(a + b × X867 + 2 × s)
= Exp(a + b × 1,255 + 2 × s)
= Exp(8.1451 + -0.0026 × 1,255 + 2 × 0.1892)
= Exp(5.3078)
= $201.91

Bottom border of price channel:

Exp(Y867)
= Exp(a + b × X867 – 2 × s)
= Exp(a + b × 1,255 – 2 × s)
= Exp(8.1451 + -0.0026 × 1,255 – 2 × 0.1892)
= Exp(4.5509)
= $94.71

= Exp(a + b × 1,823 + 2 × s)
= Exp(8.1451 + -0.0026 × 1,823 + 2 × 0.1892)
= Exp(3.8524)
= $47.11

Bottom border of price channel:

Exp(Y1,255)
= Exp(a + b × X1,255 – 2 × s)
= Exp(a + b × 1,823 – 2 × s)
