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 AXL 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: February 3, 2021
End date: November 20, 2024

a = 2.4550

b = -0.0003

s = 0.1094

Annual growth rate:

Exp(365 × b) – 1
= Exp(365 × -0.0003) – 1
= -10.73%

Price channel spread:

Exp(4 × s) – 1
= Exp(4 × 0.1094) – 1
= 54.91%

February 3, 2021 calculations

Top border of price channel:

Exp(Y301)
= Exp(a + b × X301 + 2 × s)
= Exp(a + b × 440 + 2 × s)
= Exp(2.4550 + -0.0003 × 440 + 2 × 0.1094)
= Exp(2.5370)
= $12.64

Bottom border of price channel:

Exp(Y301)
= Exp(a + b × X301 – 2 × s)
= Exp(a + b × 440 – 2 × s)
= Exp(2.4550 + -0.0003 × 440 – 2 × 0.1094)
= Exp(2.0993)
= $8.16

Top border of price channel:

Exp(Y1,257)
= Exp(a + b × X1,257 + 2 × s)
= Exp(a + b × 1,826 + 2 × s)
= Exp(2.4550 + -0.0003 × 1,826 + 2 × 0.1094)
= Exp(2.1058)
= $8.21

Bottom border of price channel:

Exp(Y1,257)
= Exp(a + b × X1,257 – 2 × s)
= Exp(a + b × 1,826 – 2 × s)
= Exp(2.4550 + -0.0003 × 1,826 – 2 × 0.1094)
= Exp(1.6681)
= $5.30

a = 3.5043

b = -0.0009

s = 0.0617

Annual growth rate:

Exp(365 × b) – 1
= Exp(365 × -0.0009) – 1
= -29.03%

Price channel spread:

Exp(4 × s) – 1
= Exp(4 × 0.0617) – 1
= 27.99%

Top border of price channel:

Exp(Y1,020)
= Exp(a + b × X1,020 + 2 × s)
= Exp(a + b × 1,482 + 2 × s)
= Exp(3.5043 + -0.0009 × 1,482 + 2 × 0.0617)
= Exp(2.2353)
= $9.35

Bottom border of price channel:
