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 FFIV 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: February 21, 2023
End date: July 11, 2025

a = 3.9811

b = 0.0009

s = 0.0780

Annual growth rate:

Exp(365 × b) – 1
= Exp(365 × 0.0009) – 1
= 40.17%

Price channel spread:

Exp(4 × s) – 1
= Exp(4 × 0.0780) – 1
= 36.60%

February 21, 2023 calculations

Top border of price channel:

Exp(Y656)
= Exp(a + b × X656 + 2 × s)
= Exp(a + b × 952 + 2 × s)
= Exp(3.9811 + 0.0009 × 952 + 2 × 0.0780)
= Exp(5.0179)
= $151.09

Bottom border of price channel:

Exp(Y656)
= Exp(a + b × X656 – 2 × s)
= Exp(a + b × 952 – 2 × s)
= Exp(3.9811 + 0.0009 × 952 – 2 × 0.0780)
= Exp(4.7060)
= $110.61

= Exp(a + b × 1,823 + 2 × s)
= Exp(3.9811 + 0.0009 × 1,823 + 2 × 0.0780)
= Exp(5.8238)
= $338.25

Bottom border of price channel:

Exp(Y1,254)
= Exp(a + b × X1,254 – 2 × s)
= Exp(a + b × 1,823 – 2 × s)
