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 SPXC 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: February 23, 2022
End date: December 17, 2024
a = 2.8992
b = 0.0013
s = 0.0835
Annual growth rate:
Exp(365 × b) – 1
= Exp(365 × 0.0013) – 1
= 59.86%
Price channel spread:
Exp(4 × s) – 1
= Exp(4 × 0.0835) – 1
= 39.65%

Top border of price channel:
Exp(Y475)
= Exp(a + b × X475 + 2 × s)
= Exp(a + b × 688 + 2 × s)
= Exp(2.8992 + 0.0013 × 688 + 2 × 0.0835)
= Exp(3.9504)
= $51.96
Bottom border of price channel:
Exp(Y475)
= Exp(a + b × X475 – 2 × s)
= Exp(a + b × 688 – 2 × s)
= Exp(2.8992 + 0.0013 × 688 – 2 × 0.0835)
= Exp(3.6164)
= $37.20
