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 RMBS 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: May 16, 2023
End date: March 28, 2025
a = 4.3933
b = -0.0002
s = 0.1340
Annual growth rate:
Exp(365 × b) – 1
= Exp(365 × -0.0002) – 1
= -8.46%
Price channel spread:
Exp(4 × s) – 1
= Exp(4 × 0.1340) – 1
= 70.90%

Top border of price channel:
Exp(Y787)
= Exp(a + b × X787 + 2 × s)
= Exp(a + b × 1,141 + 2 × s)
= Exp(4.3933 + -0.0002 × 1,141 + 2 × 0.1340)
= Exp(4.3848)
= $80.23
Bottom border of price channel:
Exp(Y787)
= Exp(a + b × X787 – 2 × s)
= Exp(a + b × 1,141 – 2 × s)
= Exp(4.3933 + -0.0002 × 1,141 – 2 × 0.1340)
= Exp(3.8490)
= $46.94

Top border of price channel:
Exp(Y1,255)
= Exp(a + b × X1,255 + 2 × s)
= Exp(a + b × 1,823 + 2 × s)
= Exp(4.3933 + -0.0002 × 1,823 + 2 × 0.1340)
= Exp(4.2196)
= $68.01
Bottom border of price channel:
Exp(Y1,255)
= Exp(a + b × X1,255 – 2 × s)
= Exp(a + b × 1,823 – 2 × s)
= Exp(4.3933 + -0.0002 × 1,823 – 2 × 0.1340)
= Exp(3.6837)
= $39.79
