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 8, 2021
End date: May 7, 2024

a = 4.8245

b = -0.0012

s = 0.1721

Annual growth rate:

Exp(365 × b) – 1
= Exp(365 × -0.0012) – 1
= -36.53%

Price channel spread:

Exp(4 × s) – 1
= Exp(4 × 0.1721) – 1
= 99.02%

March 8, 2021 calculations

Top border of price channel:

Exp(Y461)
= Exp(a + b × X461 + 2 × s)
= Exp(a + b × 670 + 2 × s)
= Exp(4.8245 + -0.0012 × 670 + 2 × 0.1721)
= Exp(4.3341)
= $76.25

Bottom border of price channel:

Exp(Y461)
= Exp(a + b × X461 – 2 × s)
= Exp(a + b × 670 – 2 × s)
= Exp(4.8245 + -0.0012 × 670 – 2 × 0.1721)
= Exp(3.6458)
= $38.31

Top border of price channel:

Exp(Y1,258)
= Exp(a + b × X1,258 + 2 × s)
= Exp(a + b × 1,826 + 2 × s)
= Exp(4.8245 + -0.0012 × 1,826 + 2 × 0.1721)
= Exp(2.8941)
= $18.07

Bottom border of price channel:

Exp(Y1,258)
= Exp(a + b × X1,258 – 2 × s)
= Exp(a + b × 1,826 – 2 × s)
= Exp(4.8245 + -0.0012 × 1,826 – 2 × 0.1721)
= Exp(2.2058)
= $9.08

a = 6.1116

b = -0.0020

s = 0.1266

Annual growth rate:

Exp(365 × b) – 1
= Exp(365 × -0.0020) – 1
= -52.06%

Price channel spread:

Exp(4 × s) – 1
= Exp(4 × 0.1266) – 1
= 65.92%

Top border of price channel:

Exp(Y1,012)
= Exp(a + b × X1,012 + 2 × s)
= Exp(a + b × 1,468 + 2 × s)
= Exp(6.1116 + -0.0020 × 1,468 + 2 × 0.1266)
= Exp(3.4081)
= $30.21

Bottom border of price channel:
