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 20, 2021
End date: July 25, 2024
a = 3.4281
b = -0.0008
s = 0.0934
Annual growth rate:
Exp(365 × b) – 1
= Exp(365 × -0.0008) – 1
= -24.43%
Price channel spread:
Exp(4 × s) – 1
= Exp(4 × 0.0934) – 1
= 45.30%

Top border of price channel:
Exp(Y458)
= Exp(a + b × X458 + 2 × s)
= Exp(a + b × 664 + 2 × s)
= Exp(3.4281 + -0.0008 × 664 + 2 × 0.0934)
= Exp(3.1054)
= $22.32
Bottom border of price channel:
Exp(Y458)
= Exp(a + b × X458 – 2 × s)
= Exp(a + b × 664 – 2 × s)
= Exp(3.4281 + -0.0008 × 664 – 2 × 0.0934)
= Exp(2.7317)
= $15.36

Top border of price channel:
Exp(Y1,257)
= Exp(a + b × X1,257 + 2 × s)
= Exp(a + b × 1,826 + 2 × s)
= Exp(3.4281 + -0.0008 × 1,826 + 2 × 0.0934)
= Exp(2.2137)
= $9.15
Bottom border of price channel:
Exp(Y1,257)
= Exp(a + b × X1,257 – 2 × s)
= Exp(a + b × 1,826 – 2 × s)
= Exp(3.4281 + -0.0008 × 1,826 – 2 × 0.0934)
= Exp(1.8400)
= $6.30
