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 NPO 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: January 22, 2024
End date: July 10, 2024

a = 5.9899

b = -0.0006

s = 0.0309

Annual growth rate:

Exp(365 × b) – 1
= Exp(365 × -0.0006) – 1
= -18.37%

Price channel spread:

Exp(4 × s) – 1
= Exp(4 × 0.0309) – 1
= 13.16%

January 22, 2024 calculations

Top border of price channel:

Exp(Y1,129)
= Exp(a + b × X1,129 + 2 × s)
= Exp(a + b × 1,641 + 2 × s)
= Exp(5.9899 + -0.0006 × 1,641 + 2 × 0.0309)
= Exp(5.1390)
= $170.54

Bottom border of price channel:

Exp(Y1,129)
= Exp(a + b × X1,129 – 2 × s)
= Exp(a + b × 1,641 – 2 × s)
= Exp(5.9899 + -0.0006 × 1,641 – 2 × 0.0309)
= Exp(5.0153)
= $150.70

July 10, 2024 calculations

Top border of price channel:

Exp(Y1,246)
= Exp(a + b × X1,246 + 2 × s)
= Exp(a + b × 1,811 + 2 × s)
= Exp(5.9899 + -0.0006 × 1,811 + 2 × 0.0309)
= Exp(5.0444)
= $155.16

Bottom border of price channel:

Exp(Y1,246)
= Exp(a + b × X1,246 – 2 × s)
= Exp(a + b × 1,811 – 2 × s)
= Exp(5.9899 + -0.0006 × 1,811 – 2 × 0.0309)
= Exp(4.9208)
= $137.11
