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 ABT 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 13, 2023
a = 4.8938
b = -0.0002
s = 0.0608
Annual growth rate:
Exp(365 × b) – 1
= Exp(365 × -0.0002) – 1
= -6.37%
Price channel spread:
Exp(4 × s) – 1
= Exp(4 × 0.0608) – 1
= 27.52%

Top border of price channel:
Exp(Y439)
= Exp(a + b × X439 + 2 × s)
= Exp(a + b × 637 + 2 × s)
= Exp(4.8938 + -0.0002 × 637 + 2 × 0.0608)
= Exp(4.9005)
= $134.35
Bottom border of price channel:
Exp(Y439)
= Exp(a + b × X439 – 2 × s)
= Exp(a + b × 637 – 2 × s)
= Exp(4.8938 + -0.0002 × 637 – 2 × 0.0608)
= Exp(4.6574)
= $105.36
