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 BSX 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: May 9, 2022
End date: April 26, 2024
a = 2.7561
b = 0.0008
s = 0.0496
Annual growth rate:
Exp(365 × b) – 1
= Exp(365 × 0.0008) – 1
= 33.03%
Price channel spread:
Exp(4 × s) – 1
= Exp(4 × 0.0496) – 1
= 21.92%

Top border of price channel:
Exp(Y764)
= Exp(a + b × X764 + 2 × s)
= Exp(a + b × 1,106 + 2 × s)
= Exp(2.7561 + 0.0008 × 1,106 + 2 × 0.0496)
= Exp(3.7199)
= $41.26
Bottom border of price channel:
Exp(Y764)
= Exp(a + b × X764 – 2 × s)
= Exp(a + b × 1,106 – 2 × s)
= Exp(2.7561 + 0.0008 × 1,106 – 2 × 0.0496)
= Exp(3.5217)
= $33.84

Bottom border of price channel:
Exp(Y1,258)
= Exp(a + b × X1,258 – 2 × s)
