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 GWRE 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: October 10, 2022
End date: March 6, 2025

a = 2.6132

b = 0.0015

s = 0.0749

Annual growth rate:

Exp(365 × b) – 1
= Exp(365 × 0.0015) – 1
= 71.85%

Price channel spread:

Exp(4 × s) – 1
= Exp(4 × 0.0749) – 1
= 34.95%

October 10, 2022 calculations

Top border of price channel:

Exp(Y650)
= Exp(a + b × X650 + 2 × s)
= Exp(a + b × 942 + 2 × s)
= Exp(2.6132 + 0.0015 × 942 + 2 × 0.0749)
= Exp(4.1605)
= $64.10

Bottom border of price channel:

Exp(Y650)
= Exp(a + b × X650 – 2 × s)
= Exp(a + b × 942 – 2 × s)
= Exp(2.6132 + 0.0015 × 942 – 2 × 0.0749)
= Exp(3.8608)
= $47.50

Top border of price channel:

Exp(Y1,252)
= Exp(a + b × X1,252 + 2 × s)
= Exp(a + b × 1,820 + 2 × s)
= Exp(2.6132 + 0.0015 × 1,820 + 2 × 0.0749)
= Exp(5.4630)
= $235.80

Bottom border of price channel:

Exp(Y1,252)
= Exp(a + b × X1,252 – 2 × s)
= Exp(a + b × 1,820 – 2 × s)
= Exp(2.6132 + 0.0015 × 1,820 – 2 × 0.0749)
= Exp(5.1633)
= $174.73

Description

s = 0.0171

Annual growth rate:

Exp(365 × b) – 1
= Exp(365 × -0.0044) – 1
= -79.85%

Price channel spread:
