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 CGNX 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: December 11, 2020
End date: April 26, 2024
a = 4.7602
b = -0.0007
s = 0.1350
Annual growth rate:
Exp(365 × b) – 1
= Exp(365 × -0.0007) – 1
= -23.34%
Price channel spread:
Exp(4 × s) – 1
= Exp(4 × 0.1350) – 1
= 71.62%

Top border of price channel:
Exp(Y267)
= Exp(a + b × X267 + 2 × s)
= Exp(a + b × 387 + 2 × s)
= Exp(4.7602 + -0.0007 × 387 + 2 × 0.1350)
= Exp(4.7484)
= $115.40
Bottom border of price channel:
Exp(Y267)
= Exp(a + b × X267 – 2 × s)
= Exp(a + b × 387 – 2 × s)
= Exp(4.7602 + -0.0007 × 387 – 2 × 0.1350)
= Exp(4.2083)
= $67.24

Top border of price channel:
Exp(Y1,114)
= Exp(a + b × X1,114 + 2 × s)
= Exp(a + b × 1,619 + 2 × s)
= Exp(4.7602 + -0.0007 × 1,619 + 2 × 0.1350)
= Exp(3.8512)
= $47.05
Bottom border of price channel:
Exp(Y1,114)
= Exp(a + b × X1,114 – 2 × s)
= Exp(a + b × 1,619 – 2 × s)
= Exp(4.7602 + -0.0007 × 1,619 – 2 × 0.1350)
= Exp(3.3111)
= $27.42
