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

Start date: March 27, 2025
End date: February 10, 2026
a = -3.9179
b = 0.0052
s = 0.1081
Annual growth rate:
Exp(365 × b) – 1
= Exp(365 × 0.0052) – 1
= 576.95%
Price channel spread:
Exp(4 × s) – 1
= Exp(4 × 0.1081) – 1
= 54.11%

Top border of price channel:
Exp(Y1,035)
= Exp(a + b × X1,035 + 2 × s)
= Exp(a + b × 1,505 + 2 × s)
= Exp(-3.9179 + 0.0052 × 1,505 + 2 × 0.1081)
= Exp(4.1838)
= $65.62
Bottom border of price channel:
Exp(Y1,035)
= Exp(a + b × X1,035 – 2 × s)
= Exp(a + b × 1,505 – 2 × s)
= Exp(-3.9179 + 0.0052 × 1,505 – 2 × 0.1081)
= Exp(3.7513)
= $42.58
