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 CALM 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: June 20, 2023
End date: February 24, 2025
a = 1.7722
b = 0.0016
s = 0.0867
Annual growth rate:
Exp(365 × b) – 1
= Exp(365 × 0.0016) – 1
= 79.91%
Price channel spread:
Exp(4 × s) – 1
= Exp(4 × 0.0867) – 1
= 41.46%

Top border of price channel:
Exp(Y789)
= Exp(a + b × X789 + 2 × s)
= Exp(a + b × 1,146 + 2 × s)
= Exp(1.7722 + 0.0016 × 1,146 + 2 × 0.0867)
= Exp(3.7896)
= $44.24
Bottom border of price channel:
Exp(Y789)
= Exp(a + b × X789 – 2 × s)
= Exp(a + b × 1,146 – 2 × s)
= Exp(1.7722 + 0.0016 × 1,146 – 2 × 0.0867)
= Exp(3.4428)
= $31.27

Top border of price channel:
Exp(Y1,210)
= Exp(a + b × X1,210 + 2 × s)
= Exp(a + b × 1,761 + 2 × s)
= Exp(1.7722 + 0.0016 × 1,761 + 2 × 0.0867)
= Exp(4.7792)
= $119.01
Bottom border of price channel:
Exp(Y1,210)
= Exp(a + b × X1,210 – 2 × s)
= Exp(a + b × 1,761 – 2 × s)
= Exp(1.7722 + 0.0016 × 1,761 – 2 × 0.0867)
= Exp(4.4323)
= $84.13
