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
Primary Trend
Start date: April 30, 2024
End date: May 23, 2025
a = 3.4892
b = 0.0008
s = 0.0354
Annual growth rate:
Exp(365 × b) – 1
= Exp(365 × 0.0008) – 1
= 32.60%
Price channel spread:
Exp(4 × s) – 1
= Exp(4 × 0.0354) – 1
= 15.22%

Exp(Y989)
= Exp(a + b × X989 + 2 × s)
= Exp(a + b × 1,435 + 2 × s)
= Exp(3.4892 + 0.0008 × 1,435 + 2 × 0.0354)
= Exp(4.6695)
= $106.65
Bottom border of price channel:
Exp(Y989)
= Exp(a + b × X989 – 2 × s)
= Exp(a + b × 1,435 – 2 × s)
= Exp(3.4892 + 0.0008 × 1,435 – 2 × 0.0354)
= Exp(4.5278)
= $92.55
