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

End date: March 3, 2025
a = 3.8875
b = 0.0003
s = 0.0863
Annual growth rate:
Exp(365 × b) – 1
= Exp(365 × 0.0003) – 1
= 12.56%
Price channel spread:
Exp(4 × s) – 1
= Exp(4 × 0.0863) – 1
= 41.21%

Top border of price channel:
Exp(Y518)
= Exp(a + b × X518 + 2 × s)
= Exp(a + b × 749 + 2 × s)
= Exp(3.8875 + 0.0003 × 749 + 2 × 0.0863)
= Exp(4.3029)
= $73.91
Bottom border of price channel:
Exp(Y518)
= Exp(a + b × X518 – 2 × s)
= Exp(a + b × 749 – 2 × s)
= Exp(3.8875 + 0.0003 × 749 – 2 × 0.0863)
= Exp(3.9578)
= $52.34
