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 JEF 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: April 4, 2025
End date: September 12, 2025
a = -0.4458
b = 0.0025
s = 0.0371
Annual growth rate:
Exp(365 × b) – 1
= Exp(365 × 0.0025) – 1
= 152.24%
Price channel spread:
Exp(4 × s) – 1
= Exp(4 × 0.0371) – 1
= 15.99%

Top border of price channel:
Exp(Y1,145)
= Exp(a + b × X1,145 + 2 × s)
= Exp(a + b × 1,663 + 2 × s)
= Exp(-0.4458 + 0.0025 × 1,663 + 2 × 0.0371)
= Exp(3.8439)
= $46.71
Bottom border of price channel:
Exp(Y1,145)
= Exp(a + b × X1,145 – 2 × s)
= Exp(a + b × 1,663 – 2 × s)
= Exp(-0.4458 + 0.0025 × 1,663 – 2 × 0.0371)
= Exp(3.6955)
= $40.27
