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 SRE 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: March 3, 2025
End date: September 11, 2025
a = 2.5178
b = 0.0010
s = 0.0298
Annual growth rate:
Exp(365 × b) – 1
= Exp(365 × 0.0010) – 1
= 46.36%
Price channel spread:
Exp(4 × s) – 1
= Exp(4 × 0.0298) – 1
= 12.67%

Top border of price channel:
Exp(Y1,121)
= Exp(a + b × X1,121 + 2 × s)
= Exp(a + b × 1,631 + 2 × s)
= Exp(2.5178 + 0.0010 × 1,631 + 2 × 0.0298)
= Exp(4.2796)
= $72.21
Bottom border of price channel:
Exp(Y1,121)
= Exp(a + b × X1,121 – 2 × s)
= Exp(a + b × 1,631 – 2 × s)
= Exp(2.5178 + 0.0010 × 1,631 – 2 × 0.0298)
= Exp(4.1603)
= $64.09
