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 QRVO 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 12, 2024
End date: January 16, 2025

a = 9.7946

b = -0.0032

s = 0.1019

Annual growth rate:

Exp(365 × b) – 1
= Exp(365 × -0.0032) – 1
= -68.89%

Price channel spread:

Exp(4 × s) – 1
= Exp(4 × 0.1019) – 1
= 50.34%

Top border of price channel:

Exp(Y1,057)
= Exp(a + b × X1,057 + 2 × s)
= Exp(a + b × 1,534 + 2 × s)
= Exp(9.7946 + -0.0032 × 1,534 + 2 × 0.1019)
= Exp(5.0906)
= $162.48

Bottom border of price channel:

Exp(Y1,057)
= Exp(a + b × X1,057 – 2 × s)
= Exp(a + b × 1,534 – 2 × s)
= Exp(9.7946 + -0.0032 × 1,534 – 2 × 0.1019)
= Exp(4.6828)
= $108.08

January 16, 2025 calculations

Top border of price channel:

Exp(Y1,206)
= Exp(a + b × X1,206 + 2 × s)
= Exp(a + b × 1,752 + 2 × s)
= Exp(9.7946 + -0.0032 × 1,752 + 2 × 0.1019)
= Exp(4.3931)
= $80.89

Bottom border of price channel:

Exp(Y1,206)
= Exp(a + b × X1,206 – 2 × s)
= Exp(a + b × 1,752 – 2 × s)
= Exp(9.7946 + -0.0032 × 1,752 – 2 × 0.1019)
= Exp(3.9854)
= $53.80
