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: April 28, 2025
a = 5.6272
b = -0.0008
s = 0.0824
Annual growth rate:
Exp(365 × b) – 1
= Exp(365 × -0.0008) – 1
= -24.03%
Price channel spread:
Exp(4 × s) – 1
= Exp(4 × 0.0824) – 1
= 39.03%

Top border of price channel:
Exp(Y952)
= Exp(a + b × X952 + 2 × s)
= Exp(a + b × 1,381 + 2 × s)
= Exp(5.6272 + -0.0008 × 1,381 + 2 × 0.0824)
= Exp(4.7519)
= $115.80
Bottom border of price channel:
Exp(Y952)
= Exp(a + b × X952 – 2 × s)
= Exp(a + b × 1,381 – 2 × s)
= Exp(5.6272 + -0.0008 × 1,381 – 2 × 0.0824)
= Exp(4.4223)
= $83.29

= Exp(4.4175)
= $82.89
Bottom border of price channel:
Exp(Y1,255)
= Exp(a + b × X1,255 – 2 × s)
= Exp(a + b × 1,825 – 2 × s)
