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 CPK 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 29, 2023
End date: May 7, 2025
a = 3.6779
b = 0.0007
s = 0.0368
Annual growth rate:
Exp(365 × b) – 1
= Exp(365 × 0.0007) – 1
= 27.72%
Price channel spread:
Exp(4 × s) – 1
= Exp(4 × 0.0368) – 1
= 15.86%

Top border of price channel:
Exp(Y854)
= Exp(a + b × X854 + 2 × s)
= Exp(a + b × 1,239 + 2 × s)
= Exp(3.6779 + 0.0007 × 1,239 + 2 × 0.0368)
= Exp(4.5820)
= $97.71
Bottom border of price channel:
Exp(Y854)
= Exp(a + b × X854 – 2 × s)
= Exp(a + b × 1,239 – 2 × s)
= Exp(3.6779 + 0.0007 × 1,239 – 2 × 0.0368)
= Exp(4.4348)
= $84.33

= Exp(a + b × X1,255 + 2 × s)
= Exp(a + b × 1,825 + 2 × s)
= Exp(3.6779 + 0.0007 × 1,825 + 2 × 0.0368)
= Exp(4.9748)
= $144.72
Bottom border of price channel:
Exp(Y1,255)
= Exp(a + b × X1,255 – 2 × s)
= Exp(a + b × 1,825 – 2 × s)
= Exp(3.6779 + 0.0007 × 1,825 – 2 × 0.0368)
= Exp(4.8276)
= $124.91
