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 PAYX 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

Start date: May 15, 2025
End date: January 7, 2026

a = 7.6118

b = -0.0016

s = 0.0283

Annual growth rate:

Exp(365 × b) – 1
= Exp(365 × -0.0016) – 1
= -44.43%

Price channel spread:

Exp(4 × s) – 1
= Exp(4 × 0.0283) – 1
= 11.98%

Top border of price channel:

Exp(Y1,091)
= Exp(a + b × X1,091 + 2 × s)
= Exp(a + b × 1,585 + 2 × s)
= Exp(7.6118 + -0.0016 × 1,585 + 2 × 0.0283)
= Exp(5.1170)
= $166.84

Bottom border of price channel:

Exp(Y1,091)
= Exp(a + b × X1,091 – 2 × s)
= Exp(a + b × 1,585 – 2 × s)
= Exp(7.6118 + -0.0016 × 1,585 – 2 × 0.0283)
= Exp(5.0039)
= $148.99
