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 S&P MidCap 400 Index
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 7, 2021
End date: December 12, 2023

a = 7.9192

b = -0.0001

s = 0.0532

Annual growth rate:

Exp(365 × b) – 1
= Exp(365 × -0.0001) – 1
= -2.43%

Price channel spread:

Exp(4 × s) – 1
= Exp(4 × 0.0532) – 1
= 23.73%

Top border of price channel:

Exp(Y327)
= Exp(a + b × X327 + 2 × s)
= Exp(a + b × 475 + 2 × s)
= Exp(7.9192 + -0.0001 × 475 + 2 × 0.0532)
= Exp(7.9937)
= 2,962.20

Bottom border of price channel:

Exp(Y327)
= Exp(a + b × X327 – 2 × s)
= Exp(a + b × 475 – 2 × s)
= Exp(7.9192 + -0.0001 × 475 – 2 × 0.0532)
= Exp(7.7807)
= 2,394.03
