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 SIG 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 8, 2021
End date: April 28, 2025
a = 4.1424
b = 0.0001
s = 0.1924
Annual growth rate:
Exp(365 × b) – 1
= Exp(365 × 0.0001) – 1
= 5.04%
Price channel spread:
Exp(4 × s) – 1
= Exp(4 × 0.1924) – 1
= 115.91%

Top border of price channel:
Exp(Y215)
= Exp(a + b × X215 + 2 × s)
= Exp(a + b × 313 + 2 × s)
= Exp(4.1424 + 0.0001 × 313 + 2 × 0.1924)
= Exp(4.5694)
= $96.48
Bottom border of price channel:
Exp(Y215)
= Exp(a + b × X215 – 2 × s)
= Exp(a + b × 313 – 2 × s)
= Exp(4.1424 + 0.0001 × 313 – 2 × 0.1924)
= Exp(3.7996)
= $44.69

Exp(Y1,255)
= Exp(a + b × X1,255 + 2 × s)
= Exp(a + b × 1,825 + 2 × s)
= Exp(4.1424 + 0.0001 × 1,825 + 2 × 0.1924)
= Exp(4.7729)
= $118.26
Bottom border of price channel:
Exp(Y1,255)
= Exp(a + b × X1,255 – 2 × s)
= Exp(a + b × 1,825 – 2 × s)
= Exp(4.1424 + 0.0001 × 1,825 – 2 × 0.1924)
= Exp(4.0032)
= $54.77
