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 NKE 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 3, 2020
End date: May 2, 2024

a = 5.2069

b = -0.0003

s = 0.1181

Annual growth rate:

Exp(365 × b) – 1
= Exp(365 × -0.0003) – 1
= -11.99%

Price channel spread:

Exp(4 × s) – 1
= Exp(4 × 0.1181) – 1
= 60.38%

Top border of price channel:

Exp(Y401)
= Exp(a + b × X401 + 2 × s)
= Exp(a + b × 580 + 2 × s)
= Exp(5.2069 + -0.0003 × 580 + 2 × 0.1181)
= Exp(5.2401)
= $188.70

Bottom border of price channel:

Exp(Y401)
= Exp(a + b × X401 – 2 × s)
= Exp(a + b × 580 – 2 × s)
= Exp(5.2069 + -0.0003 × 580 – 2 × 0.1181)
= Exp(4.7678)
= $117.66

= Exp(a + b × X1,258 + 2 × s)
= Exp(a + b × 1,826 + 2 × s)
= Exp(5.2069 + -0.0003 × 1,826 + 2 × 0.1181)
= Exp(4.8042)
= $122.03

Bottom border of price channel:

Exp(Y1,258)
= Exp(a + b × X1,258 – 2 × s)
= Exp(a + b × 1,826 – 2 × s)
= Exp(5.2069 + -0.0003 × 1,826 – 2 × 0.1181)
= Exp(4.3319)
= $76.09
