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 EBAY 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 19, 2023
End date: October 30, 2024

a = 1.5870

b = 0.0014

s = 0.0424

Annual growth rate:

Exp(365 × b) – 1
= Exp(365 × 0.0014) – 1
= 68.75%

Price channel spread:

Exp(4 × s) – 1
= Exp(4 × 0.0424) – 1
= 18.49%

October 19, 2023 calculations

Top border of price channel:

Exp(Y984)
= Exp(a + b × X984 + 2 × s)
= Exp(a + b × 1,429 + 2 × s)
= Exp(1.5870 + 0.0014 × 1,429 + 2 × 0.0424)
= Exp(3.7202)
= $41.27

Bottom border of price channel:

Exp(Y984)
= Exp(a + b × X984 – 2 × s)
= Exp(a + b × 1,429 – 2 × s)
= Exp(1.5870 + 0.0014 × 1,429 – 2 × 0.0424)
= Exp(3.5506)
= $34.83

October 30, 2024 calculations

Top border of price channel:

Exp(Y1,243)
= Exp(a + b × X1,243 + 2 × s)
= Exp(a + b × 1,806 + 2 × s)
= Exp(1.5870 + 0.0014 × 1,806 + 2 × 0.0424)
= Exp(4.2607)
= $70.86

Bottom border of price channel:

Exp(Y1,243)
= Exp(a + b × X1,243 – 2 × s)
= Exp(a + b × 1,806 – 2 × s)
= Exp(1.5870 + 0.0014 × 1,806 – 2 × 0.0424)
= Exp(4.0910)
= $59.80

Description

a = 7.8806

b = -0.0021

s = 0.0252

Annual growth rate:

Exp(365 × b) – 1
= Exp(365 × -0.0021) – 1
= -53.04%

Price channel spread:

Top border of price channel:

Exp(Y1,221)
= Exp(a + b × X1,221 + 2 × s)
= Exp(a + b × 1,776 + 2 × s)
= Exp(7.8806 + -0.0021 × 1,776 + 2 × 0.0252)
= Exp(4.2527)
= $70.30

Bottom border of price channel:
