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


Primary Trend

Start date: July 1, 2021
End date: August 21, 2024

a = 4.6323

b = 0.0001

s = 0.0571

Annual growth rate:

Exp(365 × b) – 1
= Exp(365 × 0.0001) – 1
= 2.98%

Price channel spread:

Exp(4 × s) – 1
= Exp(4 × 0.0571) – 1
= 25.66%

Top border of price channel:

Exp(Y405)
= Exp(a + b × X405 + 2 × s)
= Exp(a + b × 589 + 2 × s)
= Exp(4.6323 + 0.0001 × 589 + 2 × 0.0571)
= Exp(4.7939)
= $120.77

Bottom border of price channel:

Exp(Y405)
= Exp(a + b × X405 – 2 × s)
= Exp(a + b × 589 – 2 × s)
= Exp(4.6323 + 0.0001 × 589 – 2 × 0.0571)
= Exp(4.5655)
= $96.11

Top border of price channel:

Exp(Y1,194)
= Exp(a + b × X1,194 + 2 × s)
= Exp(a + b × 1,736 + 2 × s)
= Exp(4.6323 + 0.0001 × 1,736 + 2 × 0.0571)
= Exp(4.8862)
= $132.45

Bottom border of price channel:

Exp(Y1,194)
= Exp(a + b × X1,194 – 2 × s)
= Exp(a + b × 1,736 – 2 × s)
= Exp(4.6323 + 0.0001 × 1,736 – 2 × 0.0571)
= Exp(4.6578)
= $105.40

a = 1.9898

b = 0.0016

s = 0.0166

Annual growth rate:

Exp(365 × b) – 1
= Exp(365 × 0.0016) – 1
= 82.22%

Price channel spread:

Top border of price channel:

Exp(Y1,155)
= Exp(a + b × X1,155 + 2 × s)
= Exp(a + b × 1,680 + 2 × s)
= Exp(1.9898 + 0.0016 × 1,680 + 2 × 0.0166)
= Exp(4.7849)
= $119.69

Bottom border of price channel:
