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 REGN 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

End date: December 27, 2023
a = 6.0975
b = 0.0004
s = 0.0930
Annual growth rate:
Exp(365 × b) – 1
= Exp(365 × 0.0004) – 1
= 13.79%
Price channel spread:
Exp(4 × s) – 1
= Exp(4 × 0.0930) – 1
= 45.06%

Top border of price channel:
Exp(Y212)
= Exp(a + b × X212 + 2 × s)
= Exp(a + b × 308 + 2 × s)
= Exp(6.0975 + 0.0004 × 308 + 2 × 0.0930)
= Exp(6.3925)
= $597.37
Bottom border of price channel:
Exp(Y212)
= Exp(a + b × X212 – 2 × s)
= Exp(a + b × 308 – 2 × s)
= Exp(6.0975 + 0.0004 × 308 – 2 × 0.0930)
= Exp(6.0206)
= $411.81

= Exp(6.8863)
= $978.75
Bottom border of price channel:
Exp(Y1,175)
= Exp(a + b × X1,175 – 2 × s)
= Exp(a + b × 1,703 – 2 × s)
= Exp(6.0975 + 0.0004 × 1,703 – 2 × 0.0930)
= Exp(6.5143)
