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 TSCO 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: August 4, 2025
End date: January 9, 2026

a = 6.1113

b = -0.0012

s = 0.0233

Annual growth rate:

Exp(365 × b) – 1
= Exp(365 × -0.0012) – 1
= -35.48%

Price channel spread:

Exp(4 × s) – 1
= Exp(4 × 0.0233) – 1
= 9.75%

Top border of price channel:

Exp(Y1,145)
= Exp(a + b × X1,145 + 2 × s)
= Exp(a + b × 1,666 + 2 × s)
= Exp(6.1113 + -0.0012 × 1,666 + 2 × 0.0233)
= Exp(4.1580)
= $63.94

Bottom border of price channel:

Exp(Y1,145)
= Exp(a + b × X1,145 – 2 × s)
= Exp(a + b × 1,666 – 2 × s)
= Exp(6.1113 + -0.0012 × 1,666 – 2 × 0.0233)
= Exp(4.0649)
= $58.26

= Exp(a + b × X1,255 + 2 × s)
= Exp(a + b × 1,824 + 2 × s)
= Exp(6.1113 + -0.0012 × 1,824 + 2 × 0.0233)
= Exp(3.9683)
= $52.90

Bottom border of price channel:

Exp(Y1,255)
= Exp(a + b × X1,255 – 2 × s)
= Exp(a + b × 1,824 – 2 × s)

= Exp(3.8752)
= $48.19
