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: September 15, 2023
End date: November 15, 2024
a = 2.7860
b = 0.0010
s = 0.0560
Annual growth rate:
Exp(365 × b) – 1
= Exp(365 × 0.0010) – 1
= 42.85%
Price channel spread:
Exp(4 × s) – 1
= Exp(4 × 0.0560) – 1
= 25.12%

Top border of price channel:
Exp(Y959)
= Exp(a + b × X959 + 2 × s)
= Exp(a + b × 1,394 + 2 × s)
= Exp(2.7860 + 0.0010 × 1,394 + 2 × 0.0560)
= Exp(4.2601)
= $70.82
Bottom border of price channel:
Exp(Y959)
= Exp(a + b × X959 – 2 × s)
= Exp(a + b × 1,394 – 2 × s)
= Exp(2.7860 + 0.0010 × 1,394 – 2 × 0.0560)
= Exp(4.0360)
= $56.60

= Exp(a + b × X1,254 + 2 × s)
= Exp(a + b × 1,821 + 2 × s)
= Exp(2.7860 + 0.0010 × 1,821 + 2 × 0.0560)
= Exp(4.6773)
= $107.48
Bottom border of price channel:
Exp(Y1,254)
= Exp(a + b × X1,254 – 2 × s)
= Exp(a + b × 1,821 – 2 × s)
= Exp(2.7860 + 0.0010 × 1,821 – 2 × 0.0560)
= Exp(4.4532)
= $85.90
