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 HCA 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

Start date: December 12, 2024
End date: October 27, 2025
a = 3.9807
b = 0.0011
s = 0.0379
Annual growth rate:
Exp(365 × b) – 1
= Exp(365 × 0.0011) – 1
= 51.48%
Price channel spread:
Exp(4 × s) – 1
= Exp(4 × 0.0379) – 1
= 16.39%

Top border of price channel:
Exp(Y1,037)
= Exp(a + b × X1,037 + 2 × s)
= Exp(a + b × 1,506 + 2 × s)
= Exp(3.9807 + 0.0011 × 1,506 + 2 × 0.0379)
= Exp(5.7701)
= $320.57
Bottom border of price channel:
Exp(Y1,037)
= Exp(a + b × X1,037 – 2 × s)
= Exp(a + b × 1,506 – 2 × s)
= Exp(3.9807 + 0.0011 × 1,506 – 2 × 0.0379)
= Exp(5.6183)
= $275.43
