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 ALKS 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: June 8, 2021
End date: January 17, 2025
a = 3.2528
b = 0.0000
s = 0.0971
Annual growth rate:
Exp(365 × b) – 1
= Exp(365 × 0.0000) – 1
= 1.28%
Price channel spread:
Exp(4 × s) – 1
= Exp(4 × 0.0971) – 1
= 47.45%

Top border of price channel:
Exp(Y343)
= Exp(a + b × X343 + 2 × s)
= Exp(a + b × 497 + 2 × s)
= Exp(3.2528 + 0.0000 × 497 + 2 × 0.0971)
= Exp(3.4642)
= $31.95
Bottom border of price channel:
Exp(Y343)
= Exp(a + b × X343 – 2 × s)
= Exp(a + b × 497 – 2 × s)
= Exp(3.2528 + 0.0000 × 497 – 2 × 0.0971)
= Exp(3.0759)
= $21.67

= Exp(3.5100)
= $33.45
Bottom border of price channel:
Exp(Y1,251)
= Exp(a + b × X1,251 – 2 × s)
= Exp(a + b × 1,816 – 2 × s)
