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 ABBV 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 15, 2021
End date: December 29, 2023
a = 4.7907
b = 0.0001
s = 0.0584
Annual growth rate:
Exp(365 × b) – 1
= Exp(365 × 0.0001) – 1
= 4.33%
Price channel spread:
Exp(4 × s) – 1
= Exp(4 × 0.0584) – 1
= 26.29%

Top border of price channel:
Exp(Y417)
= Exp(a + b × X417 + 2 × s)
= Exp(a + b × 602 + 2 × s)
= Exp(4.7907 + 0.0001 × 602 + 2 × 0.0584)
= Exp(4.9772)
= $145.07
Bottom border of price channel:
Exp(Y417)
= Exp(a + b × X417 – 2 × s)
= Exp(a + b × 602 – 2 × s)
= Exp(4.7907 + 0.0001 × 602 – 2 × 0.0584)
= Exp(4.7438)
= $114.87

Top border of price channel:
Exp(Y929)
= Exp(a + b × X929 + 2 × s)
= Exp(a + b × 1,346 + 2 × s)
= Exp(4.7907 + 0.0001 × 1,346 + 2 × 0.0584)
= Exp(5.0635)
= $158.15
Bottom border of price channel:
Exp(Y929)
= Exp(a + b × X929 – 2 × s)
= Exp(a + b × 1,346 – 2 × s)
= Exp(4.7907 + 0.0001 × 1,346 – 2 × 0.0584)
= Exp(4.8301)
