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 2, 2025
a = 5.2711
b = -0.0011
s = 0.0391
Annual growth rate:
Exp(365 × b) – 1
= Exp(365 × -0.0011) – 1
= -33.41%
Price channel spread:
Exp(4 × s) – 1
= Exp(4 × 0.0391) – 1
= 16.91%

Top border of price channel:
Exp(Y373)
= Exp(a + b × X373 + 2 × s)
= Exp(a + b × 540 + 2 × s)
= Exp(5.2711 + -0.0011 × 540 + 2 × 0.0391)
= Exp(4.7477)
= $115.32
Bottom border of price channel:
Exp(Y373)
= Exp(a + b × X373 – 2 × s)
= Exp(a + b × 540 – 2 × s)
= Exp(5.2711 + -0.0011 × 540 – 2 × 0.0391)
= Exp(4.5915)
= $98.64

= Exp(4.6018)
= $99.66
Bottom border of price channel:
Exp(Y460)
= Exp(a + b × X460 – 2 × s)
= Exp(a + b × 671 – 2 × s)
= Exp(5.2711 + -0.0011 × 671 – 2 × 0.0391)
= Exp(4.4455)
