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 DLTR 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: March 9, 2022
End date: July 26, 2024

a = 5.4904

b = -0.0004

s = 0.0891

Annual growth rate:

Exp(365 × b) – 1
= Exp(365 × -0.0004) – 1
= -13.69%

Price channel spread:

Exp(4 × s) – 1
= Exp(4 × 0.0891) – 1
= 42.80%

March 9, 2022 calculations

Top border of price channel:

Exp(Y659)
= Exp(a + b × X659 + 2 × s)
= Exp(a + b × 954 + 2 × s)
= Exp(5.4904 + -0.0004 × 954 + 2 × 0.0891)
= Exp(5.2837)
= $197.09

Bottom border of price channel:

Exp(Y659)
= Exp(a + b × X659 – 2 × s)
= Exp(a + b × 954 – 2 × s)
= Exp(5.4904 + -0.0004 × 954 – 2 × 0.0891)
= Exp(4.9274)
= $138.02

July 26, 2024 calculations

Top border of price channel:

Exp(Y1,257)
= Exp(a + b × X1,257 + 2 × s)
= Exp(a + b × 1,824 + 2 × s)
= Exp(5.4904 + -0.0004 × 1,824 + 2 × 0.0891)
= Exp(4.9327)
= $138.75

Bottom border of price channel:

Exp(Y1,257)
= Exp(a + b × X1,257 – 2 × s)
= Exp(a + b × 1,824 – 2 × s)
= Exp(5.4904 + -0.0004 × 1,824 – 2 × 0.0891)
= Exp(4.5764)
= $97.16

a = 8.6113

b = -0.0022

s = 0.0351

Annual growth rate:

Exp(365 × b) – 1
= Exp(365 × -0.0022) – 1
= -55.04%

Price channel spread:

Exp(4 × s) – 1
= Exp(4 × 0.0351) – 1
= 15.07%
