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 JBGS 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: March 3, 2023
End date: August 21, 2025
a = 2.2579
b = 0.0003
s = 0.0806
Annual growth rate:
Exp(365 × b) – 1
= Exp(365 × 0.0003) – 1
= 12.53%
Price channel spread:
Exp(4 × s) – 1
= Exp(4 × 0.0806) – 1
= 38.02%

Top border of price channel:
Exp(Y635)
= Exp(a + b × X635 + 2 × s)
= Exp(a + b × 921 + 2 × s)
= Exp(2.2579 + 0.0003 × 921 + 2 × 0.0806)
= Exp(2.7168)
= $15.13
Bottom border of price channel:
Exp(Y635)
= Exp(a + b × X635 – 2 × s)
= Exp(a + b × 921 – 2 × s)
= Exp(2.2579 + 0.0003 × 921 – 2 × 0.0806)
= Exp(2.3946)
= $10.96

Top border of price channel:
Exp(Y1,254)
= Exp(a + b × X1,254 + 2 × s)
= Exp(a + b × 1,823 + 2 × s)
= Exp(2.2579 + 0.0003 × 1,823 + 2 × 0.0806)
= Exp(3.0085)
= $20.26
Bottom border of price channel:
Exp(Y1,254)
= Exp(a + b × X1,254 – 2 × s)
= Exp(a + b × 1,823 – 2 × s)
= Exp(2.2579 + 0.0003 × 1,823 – 2 × 0.0806)
= Exp(2.6863)
= $14.68
