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 BDX 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 6, 2023
End date: April 29, 2025
a = 5.7455
b = -0.0002
s = 0.0409
Annual growth rate:
Exp(365 × b) – 1
= Exp(365 × -0.0002) – 1
= -6.78%
Price channel spread:
Exp(4 × s) – 1
= Exp(4 × 0.0409) – 1
= 17.78%

Top border of price channel:
Exp(Y739)
= Exp(a + b × X739 + 2 × s)
= Exp(a + b × 1,071 + 2 × s)
= Exp(5.7455 + -0.0002 × 1,071 + 2 × 0.0409)
= Exp(5.6214)
= $276.29
Bottom border of price channel:
Exp(Y739)
= Exp(a + b × X739 – 2 × s)
= Exp(a + b × 1,071 – 2 × s)
= Exp(5.7455 + -0.0002 × 1,071 – 2 × 0.0409)
= Exp(5.4578)
= $234.57
