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

End date: February 28, 2025
a = 1.8388
b = 0.0016
s = 0.1101
Annual growth rate:
Exp(365 × b) – 1
= Exp(365 × 0.0016) – 1
= 77.09%
Price channel spread:
Exp(4 × s) – 1
= Exp(4 × 0.1101) – 1
= 55.30%

Top border of price channel:
Exp(Y724)
= Exp(a + b × X724 + 2 × s)
= Exp(a + b × 1,050 + 2 × s)
= Exp(1.8388 + 0.0016 × 1,050 + 2 × 0.1101)
= Exp(3.7030)
= $40.57
Bottom border of price channel:
Exp(Y724)
= Exp(a + b × X724 – 2 × s)
= Exp(a + b × 1,050 – 2 × s)
= Exp(1.8388 + 0.0016 × 1,050 – 2 × 0.1101)
= Exp(3.2627)
= $26.12

= Exp(4.8272)
= $124.86
Bottom border of price channel:
Exp(Y1,217)
= Exp(a + b × X1,217 – 2 × s)
= Exp(a + b × 1,768 – 2 × s)
