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 QCOM 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: May 13, 2024
End date: January 14, 2025

a = 7.0907

b = -0.0012

s = 0.0564

Annual growth rate:

Exp(365 × b) – 1
= Exp(365 × -0.0012) – 1
= -35.23%

Price channel spread:

Exp(4 × s) – 1
= Exp(4 × 0.0564) – 1
= 25.31%

Top border of price channel:

Exp(Y1,037)
= Exp(a + b × X1,037 + 2 × s)
= Exp(a + b × 1,505 + 2 × s)
= Exp(7.0907 + -0.0012 × 1,505 + 2 × 0.0564)
= Exp(5.4124)
= $224.17

Bottom border of price channel:

Exp(Y1,037)
= Exp(a + b × X1,037 – 2 × s)
= Exp(a + b × 1,505 – 2 × s)
= Exp(7.0907 + -0.0012 × 1,505 – 2 × 0.0564)
= Exp(5.1868)
= $178.89

January 14, 2025 calculations

Top border of price channel:

Exp(Y1,205)
= Exp(a + b × X1,205 + 2 × s)
= Exp(a + b × 1,751 + 2 × s)
= Exp(7.0907 + -0.0012 × 1,751 + 2 × 0.0564)
= Exp(5.1196)
= $167.27

Bottom border of price channel:

Exp(Y1,205)
= Exp(a + b × X1,205 – 2 × s)
= Exp(a + b × 1,751 – 2 × s)
= Exp(7.0907 + -0.0012 × 1,751 – 2 × 0.0564)
= Exp(4.8940)
= $133.48
