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 CNM 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
Primary Trend
Start date: September 16, 2022
End date: August 1, 2024
a = 2.1958
b = 0.0017
s = 0.1072
Annual growth rate:
Exp(365 × b) – 1
= Exp(365 × 0.0017) – 1
= 84.17%
Price channel spread:
Exp(4 × s) – 1
= Exp(4 × 0.1072) – 1
= 53.54%

Top border of price channel:
Exp(Y291)
= Exp(a + b × X291 + 2 × s)
= Exp(a + b × 421 + 2 × s)
= Exp(2.1958 + 0.0017 × 421 + 2 × 0.1072)
= Exp(3.1146)
= $22.52
Bottom border of price channel:
Exp(Y291)
= Exp(a + b × X291 – 2 × s)
= Exp(a + b × 421 – 2 × s)
= Exp(2.1958 + 0.0017 × 421 – 2 × 0.1072)
= Exp(2.6858)
= $14.67

Top border of price channel:
Exp(Y761)
= Exp(a + b × X761 + 2 × s)
= Exp(a + b × 1,106 + 2 × s)
= Exp(2.1958 + 0.0017 × 1,106 + 2 × 0.1072)
= Exp(4.2607)
= $70.86
Bottom border of price channel:
Exp(Y761)
= Exp(a + b × X761 – 2 × s)
= Exp(a + b × 1,106 – 2 × s)
= Exp(2.1958 + 0.0017 × 1,106 – 2 × 0.1072)
= Exp(3.8319)
= $46.15

a = 3.9961
b = -0.0001
s = 0.0987
Annual growth rate:
Exp(365 × b) – 1
= Exp(365 × -0.0001) – 1
