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
Primary Trend
Start date: December 27, 2021
End date: December 29, 2023
a = 4.8048
b = 0.0001
s = 0.0570
Annual growth rate:
Exp(365 × b) – 1
= Exp(365 × 0.0001) – 1
= 3.81%
Price channel spread:
Exp(4 × s) – 1
= Exp(4 × 0.0570) – 1
= 25.59%

Top border of price channel:
Exp(Y672)
= Exp(a + b × X672 + 2 × s)
= Exp(a + b × 973 + 2 × s)
= Exp(4.8048 + 0.0001 × 973 + 2 × 0.0570)
= Exp(5.0184)
= $151.17
Bottom border of price channel:
Exp(Y672)
= Exp(a + b × X672 – 2 × s)
= Exp(a + b × 973 – 2 × s)
= Exp(4.8048 + 0.0001 × 973 – 2 × 0.0570)
= Exp(4.7906)
= $120.37

= Exp(a + b × 1,705 + 2 × s)
= Exp(4.8048 + 0.0001 × 1,705 + 2 × 0.0570)
= Exp(5.0934)
= $162.94
Bottom border of price channel:
Exp(Y1,177)
= Exp(a + b × X1,177 – 2 × s)
= Exp(a + b × 1,705 – 2 × s)
