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 SEIC 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: June 10, 2022
End date: November 19, 2024

a = 3.6096

b = 0.0004

s = 0.0560

Annual growth rate:

Exp(365 × b) – 1
= Exp(365 × 0.0004) – 1
= 13.89%

Price channel spread:

Exp(4 × s) – 1
= Exp(4 × 0.0560) – 1
= 25.12%

Top border of price channel:

Exp(Y643)
= Exp(a + b × X643 + 2 × s)
= Exp(a + b × 933 + 2 × s)
= Exp(3.6096 + 0.0004 × 933 + 2 × 0.0560)
= Exp(4.0541)
= $57.64

Bottom border of price channel:

Exp(Y643)
= Exp(a + b × X643 – 2 × s)
= Exp(a + b × 933 – 2 × s)
= Exp(3.6096 + 0.0004 × 933 – 2 × 0.0560)
= Exp(3.8300)
= $46.06

= Exp(a + b × 1,826 + 2 × s)
= Exp(3.6096 + 0.0004 × 1,826 + 2 × 0.0560)
= Exp(4.3724)
= $79.23

Bottom border of price channel:

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