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 GME 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: March 5, 2021
End date: May 8, 2024

a = 4.7208

b = -0.0012

s = 0.1728

Annual growth rate:

Exp(365 × b) – 1
= Exp(365 × -0.0012) – 1
= -36.43%

Price channel spread:

Exp(4 × s) – 1
= Exp(4 × 0.1728) – 1
= 99.58%

March 5, 2021 calculations

Top border of price channel:

Exp(Y405)
= Exp(a + b × X405 + 2 × s)
= Exp(a + b × 588 + 2 × s)
= Exp(4.7208 + -0.0012 × 588 + 2 × 0.1728)
= Exp(4.3364)
= $76.43

Bottom border of price channel:

Exp(Y405)
= Exp(a + b × X405 – 2 × s)
= Exp(a + b × 588 – 2 × s)
= Exp(4.7208 + -0.0012 × 588 – 2 × 0.1728)
= Exp(3.6453)
= $38.30

May 8, 2024 calculations

Top border of price channel:

Exp(Y1,204)
= Exp(a + b × X1,204 + 2 × s)
= Exp(a + b × 1,748 + 2 × s)
= Exp(4.7208 + -0.0012 × 1,748 + 2 × 0.1728)
= Exp(2.8965)
= $18.11

Bottom border of price channel:

Exp(Y1,204)
= Exp(a + b × X1,204 – 2 × s)
= Exp(a + b × 1,748 – 2 × s)
= Exp(4.7208 + -0.0012 × 1,748 – 2 × 0.1728)
= Exp(2.2054)
= $9.07

a = -0.5022

b = 0.0020

s = 0.2526

Annual growth rate:

Exp(365 × b) – 1
= Exp(365 × 0.0020) – 1

October 2, 2023 calculations

Top border of price channel:

Exp(Y1,053)
= Exp(a + b × X1,053 + 2 × s)
= Exp(a + b × 1,529 + 2 × s)
= Exp(-0.5022 + 0.0020 × 1,529 + 2 × 0.2526)
= Exp(3.0050)
= $20.19
