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 WAL 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: March 13, 2023
End date: January 28, 2025
a = 1.6396
b = 0.0016
s = 0.1094
Annual growth rate:
Exp(365 × b) – 1
= Exp(365 × 0.0016) – 1
= 80.14%
Price channel spread:
Exp(4 × s) – 1
= Exp(4 × 0.1094) – 1
= 54.92%

Top border of price channel:
Exp(Y785)
= Exp(a + b × X785 + 2 × s)
= Exp(a + b × 1,139 + 2 × s)
= Exp(1.6396 + 0.0016 × 1,139 + 2 × 0.1094)
= Exp(3.6951)
= $40.25
Bottom border of price channel:
Exp(Y785)
= Exp(a + b × X785 – 2 × s)
= Exp(a + b × 1,139 – 2 × s)
= Exp(1.6396 + 0.0016 × 1,139 – 2 × 0.1094)
= Exp(3.2573)
= $25.98

= Exp(a + b × X1,256 + 2 × s)
= Exp(a + b × 1,826 + 2 × s)
= Exp(1.6396 + 0.0016 × 1,826 + 2 × 0.1094)
= Exp(4.8029)
= $121.86
Bottom border of price channel:
Exp(Y1,256)
= Exp(a + b × X1,256 – 2 × s)
= Exp(a + b × 1,826 – 2 × s)
= Exp(1.6396 + 0.0016 × 1,826 – 2 × 0.1094)
= Exp(4.3651)
= $78.66
