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 LFUS 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: January 5, 2021
End date: April 29, 2025
a = 5.5851
b = -0.0001
s = 0.0958
Annual growth rate:
Exp(365 × b) – 1
= Exp(365 × -0.0001) – 1
= -2.73%
Price channel spread:
Exp(4 × s) – 1
= Exp(4 × 0.0958) – 1
= 46.71%

Top border of price channel:
Exp(Y172)
= Exp(a + b × X172 + 2 × s)
= Exp(a + b × 250 + 2 × s)
= Exp(5.5851 + -0.0001 × 250 + 2 × 0.0958)
= Exp(5.7578)
= $316.66
Bottom border of price channel:
Exp(Y172)
= Exp(a + b × X172 – 2 × s)
= Exp(a + b × 250 – 2 × s)
= Exp(5.5851 + -0.0001 × 250 – 2 × 0.0958)
= Exp(5.3745)
= $215.84

Top border of price channel:
Exp(Y1,255)
= Exp(a + b × X1,255 + 2 × s)
= Exp(a + b × 1,825 + 2 × s)
= Exp(5.5851 + -0.0001 × 1,825 + 2 × 0.0958)
= Exp(5.6383)
= $280.99
Bottom border of price channel:
Exp(Y1,255)
= Exp(a + b × X1,255 – 2 × s)
= Exp(a + b × 1,825 – 2 × s)
= Exp(5.5851 + -0.0001 × 1,825 – 2 × 0.0958)
= Exp(5.2550)
= $191.53
