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: August 2, 2024
End date: December 2, 2024
a = 2.9466
b = 0.0031
s = 0.0358
Annual growth rate:
Exp(365 × b) – 1
= Exp(365 × 0.0031) – 1
= 210.92%
Price channel spread:
Exp(4 × s) – 1
= Exp(4 × 0.0358) – 1
= 15.39%

Top border of price channel:
Exp(Y294)
= Exp(a + b × X294 + 2 × s)
= Exp(a + b × 428 + 2 × s)
= Exp(2.9466 + 0.0031 × 428 + 2 × 0.0358)
= Exp(4.3484)
= $77.35
Bottom border of price channel:
Exp(Y294)
= Exp(a + b × X294 – 2 × s)
= Exp(a + b × 428 – 2 × s)
= Exp(2.9466 + 0.0031 × 428 – 2 × 0.0358)
= Exp(4.2052)
= $67.03

= Exp(2.9466 + 0.0031 × 550 + 2 × 0.0358)
= Exp(4.7275)
= $113.02
Bottom border of price channel:
Exp(Y378)
= Exp(a + b × X378 – 2 × s)
= Exp(a + b × 550 – 2 × s)
= Exp(2.9466 + 0.0031 × 550 – 2 × 0.0358)
= Exp(4.5844)
