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 VMI 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: February 8, 2021
End date: October 10, 2024

a = 5.4375

b = 0.0001

s = 0.1254

Annual growth rate:

Exp(365 × b) – 1
= Exp(365 × 0.0001) – 1
= 2.90%

Price channel spread:

Exp(4 × s) – 1
= Exp(4 × 0.1254) – 1
= 65.11%

February 8, 2021 calculations

Top border of price channel:

Exp(Y305)
= Exp(a + b × X305 + 2 × s)
= Exp(a + b × 446 + 2 × s)
= Exp(5.4375 + 0.0001 × 446 + 2 × 0.1254)
= Exp(5.7233)
= $305.90

Bottom border of price channel:

Exp(Y305)
= Exp(a + b × X305 – 2 × s)
= Exp(a + b × 446 – 2 × s)
= Exp(5.4375 + 0.0001 × 446 – 2 × 0.1254)
= Exp(5.2218)
= $185.27

Top border of price channel:

Exp(Y1,229)
= Exp(a + b × X1,229 + 2 × s)
= Exp(a + b × 1,786 + 2 × s)
= Exp(5.4375 + 0.0001 × 1,786 + 2 × 0.1254)
= Exp(5.8284)
= $339.81

Bottom border of price channel:

Exp(Y1,229)
= Exp(a + b × X1,229 – 2 × s)
= Exp(a + b × 1,786 – 2 × s)
= Exp(5.4375 + 0.0001 × 1,786 – 2 × 0.1254)
= Exp(5.3269)
= $205.80
