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 6, 2023
End date: April 28, 2025

a = 7.6763

b = -0.0021

s = 0.1689

Annual growth rate:

Exp(365 × b) – 1
= Exp(365 × -0.0021) – 1
= -54.15%

Price channel spread:

Exp(4 × s) – 1
= Exp(4 × 0.1689) – 1
= 96.51%

December 6, 2023 calculations

Top border of price channel:

Exp(Y908)
= Exp(a + b × X908 + 2 × s)
= Exp(a + b × 1,316 + 2 × s)
= Exp(7.6763 + -0.0021 × 1,316 + 2 × 0.1689)
= Exp(5.2028)
= $181.77

Bottom border of price channel:

Exp(Y908)
= Exp(a + b × X908 – 2 × s)
= Exp(a + b × 1,316 – 2 × s)
= Exp(7.6763 + -0.0021 × 1,316 – 2 × 0.1689)
= Exp(4.5272)
= $92.50

Top border of price channel:

Exp(Y1,255)
= Exp(a + b × X1,255 + 2 × s)
= Exp(a + b × 1,825 + 2 × s)
= Exp(7.6763 + -0.0021 × 1,825 + 2 × 0.1689)
= Exp(4.1154)
= $61.28

Bottom border of price channel:

Exp(Y1,255)
= Exp(a + b × X1,255 – 2 × s)
= Exp(a + b × 1,825 – 2 × s)
= Exp(7.6763 + -0.0021 × 1,825 – 2 × 0.1689)
= Exp(3.4398)
= $31.18
