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 DOV 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: August 10, 2023
End date: November 20, 2024

a = 3.6797

b = 0.0009

s = 0.0464

Annual growth rate:

Exp(365 × b) – 1
= Exp(365 × 0.0009) – 1
= 38.45%

Price channel spread:

Exp(4 × s) – 1
= Exp(4 × 0.0464) – 1
= 20.42%

Top border of price channel:

Exp(Y934)
= Exp(a + b × X934 + 2 × s)
= Exp(a + b × 1,358 + 2 × s)
= Exp(3.6797 + 0.0009 × 1,358 + 2 × 0.0464)
= Exp(4.9832)
= $145.94

Bottom border of price channel:

Exp(Y934)
= Exp(a + b × X934 – 2 × s)
= Exp(a + b × 1,358 – 2 × s)
= Exp(3.6797 + 0.0009 × 1,358 – 2 × 0.0464)
= Exp(4.7974)
= $121.20

= Exp(5.4004)
= $221.49

Bottom border of price channel:

Exp(Y1,257)
= Exp(a + b × X1,257 – 2 × s)
= Exp(a + b × 1,826 – 2 × s)
