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: January 3, 2023
End date: March 31, 2025

a = 5.4909

b = -0.0007

s = 0.0687

Annual growth rate:

Exp(365 × b) – 1
= Exp(365 × -0.0007) – 1
= -21.74%

Price channel spread:

Exp(4 × s) – 1
= Exp(4 × 0.0687) – 1
= 31.65%

January 3, 2023 calculations

Top border of price channel:

Exp(Y694)
= Exp(a + b × X694 + 2 × s)
= Exp(a + b × 1,007 + 2 × s)
= Exp(5.4909 + -0.0007 × 1,007 + 2 × 0.0687)
= Exp(4.9521)
= $141.47

Bottom border of price channel:

Exp(Y694)
= Exp(a + b × X694 – 2 × s)
= Exp(a + b × 1,007 – 2 × s)
= Exp(5.4909 + -0.0007 × 1,007 – 2 × 0.0687)
= Exp(4.6771)
= $107.46

Top border of price channel:

Exp(Y1,255)
= Exp(a + b × X1,255 + 2 × s)
= Exp(a + b × 1,825 + 2 × s)
= Exp(5.4909 + -0.0007 × 1,825 + 2 × 0.0687)
= Exp(4.4027)
= $81.67

Bottom border of price channel:

Exp(Y1,255)
= Exp(a + b × X1,255 – 2 × s)
= Exp(a + b × 1,825 – 2 × s)
= Exp(5.4909 + -0.0007 × 1,825 – 2 × 0.0687)
= Exp(4.1277)
= $62.04
