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 BWA 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: January 26, 2023
End date: April 28, 2025
a = 4.1750
b = -0.0004
s = 0.0688
Annual growth rate:
Exp(365 × b) – 1
= Exp(365 × -0.0004) – 1
= -14.83%
Price channel spread:
Exp(4 × s) – 1
= Exp(4 × 0.0688) – 1
= 31.66%

Top border of price channel:
Exp(Y691)
= Exp(a + b × X691 + 2 × s)
= Exp(a + b × 1,002 + 2 × s)
= Exp(4.1750 + -0.0004 × 1,002 + 2 × 0.0688)
= Exp(3.8719)
= $48.03
Bottom border of price channel:
Exp(Y691)
= Exp(a + b × X691 – 2 × s)
= Exp(a + b × 1,002 – 2 × s)
= Exp(4.1750 + -0.0004 × 1,002 – 2 × 0.0688)
= Exp(3.5969)
= $36.48

Top border of price channel:
Exp(Y1,255)
= Exp(a + b × X1,255 + 2 × s)
= Exp(a + b × 1,825 + 2 × s)
= Exp(4.1750 + -0.0004 × 1,825 + 2 × 0.0688)
= Exp(3.5100)
= $33.45
Bottom border of price channel:
Exp(Y1,255)
= Exp(a + b × X1,255 – 2 × s)
= Exp(a + b × 1,825 – 2 × s)
= Exp(4.1750 + -0.0004 × 1,825 – 2 × 0.0688)
= Exp(3.2350)
= $25.41
