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 BDC 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: September 20, 2024
End date: May 9, 2025

a = 6.2979

b = -0.0010

s = 0.0524

Annual growth rate:

Exp(365 × b) – 1
= Exp(365 × -0.0010) – 1
= -29.59%

Price channel spread:

Exp(4 × s) – 1
= Exp(4 × 0.0524) – 1
= 23.33%

September 20, 2024 calculations

Top border of price channel:

Exp(Y1,054)
= Exp(a + b × X1,054 + 2 × s)
= Exp(a + b × 1,529 + 2 × s)
= Exp(6.2979 + -0.0010 × 1,529 + 2 × 0.0524)
= Exp(4.9332)
= $138.82

Bottom border of price channel:

Exp(Y1,054)
= Exp(a + b × X1,054 – 2 × s)
= Exp(a + b × 1,529 – 2 × s)
= Exp(6.2979 + -0.0010 × 1,529 – 2 × 0.0524)
= Exp(4.7234)
= $112.56

May 9, 2025 calculations

Top border of price channel:

Exp(Y1,212)
= Exp(a + b × X1,212 + 2 × s)
= Exp(a + b × 1,760 + 2 × s)
= Exp(6.2979 + -0.0010 × 1,760 + 2 × 0.0524)
= Exp(4.7111)
= $111.18

Bottom border of price channel:

Exp(Y1,212)
= Exp(a + b × X1,212 – 2 × s)
= Exp(a + b × 1,760 – 2 × s)
= Exp(6.2979 + -0.0010 × 1,760 – 2 × 0.0524)
= Exp(4.5014)
= $90.15
