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: November 14, 2024
End date: November 5, 2025

a = 4.2101

b = 0.0001

s = 0.0488

Annual growth rate:

Exp(365 × b) – 1
= Exp(365 × 0.0001) – 1
= 2.53%

Price channel spread:

Exp(4 × s) – 1
= Exp(4 × 0.0488) – 1
= 21.56%

Top border of price channel:

Exp(Y1,011)
= Exp(a + b × X1,011 + 2 × s)
= Exp(a + b × 1,469 + 2 × s)
= Exp(4.2101 + 0.0001 × 1,469 + 2 × 0.0488)
= Exp(4.4082)
= $82.12

Bottom border of price channel:

Exp(Y1,011)
= Exp(a + b × X1,011 – 2 × s)
= Exp(a + b × 1,469 – 2 × s)
= Exp(4.2101 + 0.0001 × 1,469 – 2 × 0.0488)
= Exp(4.2129)
= $67.56

= Exp(a + b × 1,825 + 2 × s)
= Exp(4.2101 + 0.0001 × 1,825 + 2 × 0.0488)
= Exp(4.4326)
= $84.15

Bottom border of price channel:

Exp(Y1,254)
= Exp(a + b × X1,254 – 2 × s)
= Exp(a + b × 1,825 – 2 × s)
