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: January 9, 2026

a = 4.1959

b = 0.0001

s = 0.0459

Annual growth rate:

Exp(365 × b) – 1
= Exp(365 × 0.0001) – 1
= 2.98%

Price channel spread:

Exp(4 × s) – 1
= Exp(4 × 0.0459) – 1
= 20.14%

Top border of price channel:

Exp(Y967)
= Exp(a + b × X967 + 2 × s)
= Exp(a + b × 1,402 + 2 × s)
= Exp(4.1959 + 0.0001 × 1,402 + 2 × 0.0459)
= Exp(4.4006)
= $81.50

Bottom border of price channel:

Exp(Y967)
= Exp(a + b × X967 – 2 × s)
= Exp(a + b × 1,402 – 2 × s)
= Exp(4.1959 + 0.0001 × 1,402 – 2 × 0.0459)
= Exp(4.2171)
= $67.84

= Exp(4.1959 + 0.0001 × 1,823 + 2 × 0.0459)
= Exp(4.4345)
= $84.31

Bottom border of price channel:

Exp(Y1,254)
