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 UNM 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 3, 2024
End date: December 6, 2024

a = -3.0366

b = 0.0041

s = 0.0250

Annual growth rate:

Exp(365 × b) – 1
= Exp(365 × 0.0041) – 1
= 339.09%

Price channel spread:

Exp(4 × s) – 1
= Exp(4 × 0.0250) – 1
= 10.50%

Top border of price channel:

Exp(Y1,187)
= Exp(a + b × X1,187 + 2 × s)
= Exp(a + b × 1,727 + 2 × s)
= Exp(-3.0366 + 0.0041 × 1,727 + 2 × 0.0250)
= Exp(4.0137)
= $55.35

Bottom border of price channel:

Exp(Y1,187)
= Exp(a + b × X1,187 – 2 × s)
= Exp(a + b × 1,727 – 2 × s)
= Exp(-3.0366 + 0.0041 × 1,727 – 2 × 0.0250)
= Exp(3.9138)
= $50.09

December 6, 2024 calculations

Top border of price channel:

Exp(Y1,254)
= Exp(a + b × X1,254 + 2 × s)
= Exp(a + b × 1,821 + 2 × s)
= Exp(-3.0366 + 0.0041 × 1,821 + 2 × 0.0250)
= Exp(4.3947)
= $81.02

Bottom border of price channel:

Exp(Y1,254)
= Exp(a + b × X1,254 – 2 × s)
= Exp(a + b × 1,821 – 2 × s)
= Exp(-3.0366 + 0.0041 × 1,821 – 2 × 0.0250)
= Exp(4.2949)
= $73.32
