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 WGO 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: December 18, 2020
End date: June 5, 2023

a = 4.4371

b = -0.0003

s = 0.1013

Annual growth rate:

Exp(365 × b) – 1
= Exp(365 × -0.0003) – 1
= -10.78%

Price channel spread:

Exp(4 × s) – 1
= Exp(4 × 0.1013) – 1
= 49.97%

Top border of price channel:

Exp(Y406)
= Exp(a + b × X406 + 2 × s)
= Exp(a + b × 585 + 2 × s)
= Exp(4.4371 + -0.0003 × 585 + 2 × 0.1013)
= Exp(4.4570)
= $86.23

Bottom border of price channel:

Exp(Y406)
= Exp(a + b × X406 – 2 × s)
= Exp(a + b × 585 – 2 × s)
= Exp(4.4371 + -0.0003 × 585 – 2 × 0.1013)
= Exp(4.0517)
= $57.50

June 5, 2023 calculations

Top border of price channel:

Exp(Y1,023)
= Exp(a + b × X1,023 + 2 × s)
= Exp(a + b × 1,484 + 2 × s)
= Exp(4.4371 + -0.0003 × 1,484 + 2 × 0.1013)
= Exp(4.1761)
= $65.11

Bottom border of price channel:

Exp(Y1,023)
= Exp(a + b × X1,023 – 2 × s)
= Exp(a + b × 1,484 – 2 × s)
= Exp(4.4371 + -0.0003 × 1,484 – 2 × 0.1013)
= Exp(3.7708)
= $43.42
