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: March 31, 2025
a = 5.2816
b = -0.0011
s = 0.0394
Annual growth rate:
Exp(365 × b) – 1
= Exp(365 × -0.0011) – 1
= -33.84%
Price channel spread:
Exp(4 × s) – 1
= Exp(4 × 0.0394) – 1
= 17.05%

Top border of price channel:
Exp(Y373)
= Exp(a + b × X373 + 2 × s)
= Exp(a + b × 540 + 2 × s)
= Exp(5.2816 + -0.0011 × 540 + 2 × 0.0394)
= Exp(4.7491)
= $115.48
Bottom border of price channel:
Exp(Y373)
= Exp(a + b × X373 – 2 × s)
= Exp(a + b × 540 – 2 × s)
= Exp(5.2816 + -0.0011 × 540 – 2 × 0.0394)
= Exp(4.5917)
= $98.66

Top border of price channel:
Exp(Y458)
= Exp(a + b × X458 + 2 × s)
= Exp(a + b × 669 + 2 × s)
= Exp(5.2816 + -0.0011 × 669 + 2 × 0.0394)
= Exp(4.6030)
= $99.79
Bottom border of price channel:
Exp(Y458)
= Exp(a + b × X458 – 2 × s)
= Exp(a + b × 669 – 2 × s)
= Exp(5.2816 + -0.0011 × 669 – 2 × 0.0394)
= Exp(4.4456)
= $85.26
