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 VIAV 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: May 14, 2021
End date: May 8, 2024

a = 3.4582

b = -0.0007

s = 0.0949

Annual growth rate:

Exp(365 × b) – 1
= Exp(365 × -0.0007) – 1
= -23.72%

Price channel spread:

Exp(4 × s) – 1
= Exp(4 × 0.0949) – 1
= 46.16%

May 14, 2021 calculations

Top border of price channel:

Exp(Y508)
= Exp(a + b × X508 + 2 × s)
= Exp(a + b × 736 + 2 × s)
= Exp(3.4582 + -0.0007 × 736 + 2 × 0.0949)
= Exp(3.1021)
= $22.24

Bottom border of price channel:

Exp(Y508)
= Exp(a + b × X508 – 2 × s)
= Exp(a + b × 736 – 2 × s)
= Exp(3.4582 + -0.0007 × 736 – 2 × 0.0949)
= Exp(2.7226)
= $15.22

Top border of price channel:

Exp(Y1,258)
= Exp(a + b × X1,258 + 2 × s)
= Exp(a + b × 1,826 + 2 × s)
= Exp(3.4582 + -0.0007 × 1,826 + 2 × 0.0949)
= Exp(2.2936)
= $9.91

Bottom border of price channel:

Exp(Y1,258)
= Exp(a + b × X1,258 – 2 × s)
= Exp(a + b × 1,826 – 2 × s)
= Exp(3.4582 + -0.0007 × 1,826 – 2 × 0.0949)
= Exp(1.9140)
= $6.78
