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 BBY 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: August 13, 2020
End date: December 13, 2023
a = 4.8474
b = -0.0004
s = 0.1073
Annual growth rate:
Exp(365 × b) – 1
= Exp(365 × -0.0004) – 1
= -13.48%
Price channel spread:
Exp(4 × s) – 1
= Exp(4 × 0.1073) – 1
= 53.60%

Top border of price channel:
Exp(Y314)
= Exp(a + b × X314 + 2 × s)
= Exp(a + b × 455 + 2 × s)
= Exp(4.8474 + -0.0004 × 455 + 2 × 0.1073)
= Exp(4.8815)
= $131.83
Bottom border of price channel:
Exp(Y314)
= Exp(a + b × X314 – 2 × s)
= Exp(a + b × 455 – 2 × s)
= Exp(4.8474 + -0.0004 × 455 – 2 × 0.1073)
= Exp(4.4523)
= $85.83

Top border of price channel:
Exp(Y1,153)
= Exp(a + b × X1,153 + 2 × s)
= Exp(a + b × 1,672 + 2 × s)
= Exp(4.8474 + -0.0004 × 1,672 + 2 × 0.1073)
= Exp(4.3987)
= $81.35
Bottom border of price channel:
Exp(Y1,153)
= Exp(a + b × X1,153 – 2 × s)
= Exp(a + b × 1,672 – 2 × s)
= Exp(4.8474 + -0.0004 × 1,672 – 2 × 0.1073)
= Exp(3.9696)
= $52.96
