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 LRCX 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 9, 2024
End date: March 28, 2025

a = 5.5485

b = -0.0007

s = 0.0815

Annual growth rate:

Exp(365 × b) – 1
= Exp(365 × -0.0007) – 1
= -22.22%

Price channel spread:

Exp(4 × s) – 1
= Exp(4 × 0.0815) – 1
= 38.54%

Top border of price channel:

Exp(Y972)
= Exp(a + b × X972 + 2 × s)
= Exp(a + b × 1,410 + 2 × s)
= Exp(5.5485 + -0.0007 × 1,410 + 2 × 0.0815)
= Exp(4.7409)
= $114.54

Bottom border of price channel:

Exp(Y972)
= Exp(a + b × X972 – 2 × s)
= Exp(a + b × 1,410 – 2 × s)
= Exp(5.5485 + -0.0007 × 1,410 – 2 × 0.0815)
= Exp(4.4149)
= $82.67
