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 CIEN 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: June 5, 2025
End date: December 4, 2025
a = -6.8272
b = 0.0067
s = 0.0855
Annual growth rate:
Exp(365 × b) – 1
= Exp(365 × 0.0067) – 1
= 1,053.13%
Price channel spread:
Exp(4 × s) – 1
= Exp(4 × 0.0855) – 1
= 40.78%

Top border of price channel:
Exp(Y1,128)
= Exp(a + b × X1,128 + 2 × s)
= Exp(a + b × 1,641 + 2 × s)
= Exp(-6.8272 + 0.0067 × 1,641 + 2 × 0.0855)
= Exp(4.3366)
= $76.45
Bottom border of price channel:
Exp(Y1,128)
= Exp(a + b × X1,128 – 2 × s)
= Exp(a + b × 1,641 – 2 × s)
= Exp(-6.8272 + 0.0067 × 1,641 – 2 × 0.0855)
= Exp(3.9945)
= $54.30
