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 AMD 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: January 18, 2024
End date: June 2, 2025

a = 6.9460

b = -0.0013

s = 0.0954

Annual growth rate:

Exp(365 × b) – 1
= Exp(365 × -0.0013) – 1
= -37.83%

Price channel spread:

Exp(4 × s) – 1
= Exp(4 × 0.0954) – 1
= 46.44%

January 18, 2024 calculations

Top border of price channel:

Exp(Y890)
= Exp(a + b × X890 + 2 × s)
= Exp(a + b × 1,291 + 2 × s)
= Exp(6.9460 + -0.0013 × 1,291 + 2 × 0.0954)
= Exp(5.4554)
= $234.02

Bottom border of price channel:

Exp(Y890)
= Exp(a + b × X890 – 2 × s)
= Exp(a + b × 1,291 – 2 × s)
= Exp(6.9460 + -0.0013 × 1,291 – 2 × 0.0954)
= Exp(5.0740)
= $159.81

Top border of price channel:

Exp(Y1,233)
= Exp(a + b × X1,233 + 2 × s)
= Exp(a + b × 1,792 + 2 × s)
= Exp(6.9460 + -0.0013 × 1,792 + 2 × 0.0954)
= Exp(4.8030)
= $121.87

Bottom border of price channel:

Exp(Y1,233)
= Exp(a + b × X1,233 – 2 × s)
= Exp(a + b × 1,792 – 2 × s)
= Exp(6.9460 + -0.0013 × 1,792 – 2 × 0.0954)
= Exp(4.4215)
= $83.22
