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 KNF 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: November 22, 2024
End date: April 24, 2025
a = 5.3099
b = -0.0012
s = 0.0407
Annual growth rate:
Exp(365 × b) – 1
= Exp(365 × -0.0012) – 1
= -35.01%
Price channel spread:
Exp(4 × s) – 1
= Exp(4 × 0.0407) – 1
= 17.69%

Top border of price channel:
Exp(Y373)
= Exp(a + b × X373 + 2 × s)
= Exp(a + b × 540 + 2 × s)
= Exp(5.3099 + -0.0012 × 540 + 2 × 0.0407)
= Exp(4.7539)
= $116.03
Bottom border of price channel:
Exp(Y373)
= Exp(a + b × X373 – 2 × s)
= Exp(a + b × 540 – 2 × s)
= Exp(5.3099 + -0.0012 × 540 – 2 × 0.0407)
= Exp(4.5910)
= $98.59

Exp(Y475)
= Exp(a + b × X475 + 2 × s)
= Exp(a + b × 693 + 2 × s)
= Exp(5.3099 + -0.0012 × 693 + 2 × 0.0407)
= Exp(4.5733)
= $96.86
Bottom border of price channel:
Exp(Y475)
= Exp(a + b × X475 – 2 × s)
= Exp(a + b × 693 – 2 × s)
= Exp(5.3099 + -0.0012 × 693 – 2 × 0.0407)
= Exp(4.4104)
= $82.30
