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 SPXC 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: September 5, 2023
End date: July 25, 2024

a = 0.9681

b = 0.0022

s = 0.0359

Annual growth rate:

Exp(365 × b) – 1
= Exp(365 × 0.0022) – 1
= 125.59%

Price channel spread:

Exp(4 × s) – 1
= Exp(4 × 0.0359) – 1
= 15.46%

Top border of price channel:

Exp(Y1,034)
= Exp(a + b × X1,034 + 2 × s)
= Exp(a + b × 1,502 + 2 × s)
= Exp(0.9681 + 0.0022 × 1,502 + 2 × 0.0359)
= Exp(4.3878)
= $80.47

Bottom border of price channel:
