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: January 16, 2025
End date: April 25, 2025
a = 13.4358
b = -0.0056
s = 0.0576
Annual growth rate:
Exp(365 × b) – 1
= Exp(365 × -0.0056) – 1
= -87.18%
Price channel spread:
Exp(4 × s) – 1
= Exp(4 × 0.0576) – 1
= 25.91%

Top border of price channel:
Exp(Y1,185)
= Exp(a + b × X1,185 + 2 × s)
= Exp(a + b × 1,722 + 2 × s)
= Exp(13.4358 + -0.0056 × 1,722 + 2 × 0.0576)
= Exp(3.8601)
= $47.47
Bottom border of price channel:
Exp(Y1,185)
= Exp(a + b × X1,185 – 2 × s)
= Exp(a + b × 1,722 – 2 × s)
= Exp(13.4358 + -0.0056 × 1,722 – 2 × 0.0576)
= Exp(3.6296)
= $37.70

Bottom border of price channel:
Exp(Y1,253)
= Exp(a + b × X1,253 – 2 × s)
