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 AMGN 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: December 18, 2024
End date: March 21, 2025
a = 0.8192
b = 0.0027
s = 0.0197
Annual growth rate:
Exp(365 × b) – 1
= Exp(365 × 0.0027) – 1
= 171.27%
Price channel spread:
Exp(4 × s) – 1
= Exp(4 × 0.0197) – 1
= 8.21%

Top border of price channel:
Exp(Y1,187)
= Exp(a + b × X1,187 + 2 × s)
= Exp(a + b × 1,722 + 2 × s)
= Exp(0.8192 + 0.0027 × 1,722 + 2 × 0.0197)
= Exp(5.5667)
= $261.58
Bottom border of price channel:
Exp(Y1,187)
= Exp(a + b × X1,187 – 2 × s)
