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: April 3, 2025
End date: July 9, 2025

a = -4.1579

b = 0.0048

s = 0.0578

Annual growth rate:

Exp(365 × b) – 1
= Exp(365 × 0.0048) – 1
= 467.44%

Price channel spread:

Exp(4 × s) – 1
= Exp(4 × 0.0578) – 1
= 26.02%

Top border of price channel:

Exp(Y1,189)
= Exp(a + b × X1,189 + 2 × s)
= Exp(a + b × 1,728 + 2 × s)
= Exp(-4.1579 + 0.0048 × 1,728 + 2 × 0.0578)
= Exp(4.1762)
= $65.12

Bottom border of price channel:

Exp(Y1,189)
= Exp(a + b × X1,189 – 2 × s)
= Exp(a + b × 1,728 – 2 × s)
= Exp(-4.1579 + 0.0048 × 1,728 – 2 × 0.0578)
= Exp(3.9449)
= $51.67

= Exp(a + b × 1,825 + 2 × s)
= Exp(-4.1579 + 0.0048 × 1,825 + 2 × 0.0578)
= Exp(4.6376)
= $103.29

Bottom border of price channel:

Exp(Y1,254)
= Exp(a + b × X1,254 – 2 × s)
= Exp(a + b × 1,825 – 2 × s)

= Exp(4.4063)
= $81.96
