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 LULU 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: December 6, 2024
End date: July 11, 2025
a = 10.2210
b = -0.0026
s = 0.0969
Annual growth rate:
Exp(365 × b) – 1
= Exp(365 × -0.0026) – 1
= -61.24%
Price channel spread:
Exp(4 × s) – 1
= Exp(4 × 0.0969) – 1
= 47.34%
December 6, 2024 calculations
Top border of price channel:
Exp(Y1,109)
= Exp(a + b × X1,109 + 2 × s)
= Exp(a + b × 1,607 + 2 × s)
= Exp(10.2210 + -0.0026 × 1,607 + 2 × 0.0969)
= Exp(6.2420)
= $513.88
Bottom border of price channel:
Exp(Y1,109)
= Exp(a + b × X1,109 – 2 × s)
= Exp(a + b × 1,607 – 2 × s)
= Exp(10.2210 + -0.0026 × 1,607 – 2 × 0.0969)
= Exp(5.8544)
= $348.76

Top border of price channel:
Exp(Y1,255)
= Exp(a + b × X1,255 + 2 × s)
= Exp(a + b × 1,824 + 2 × s)
= Exp(10.2210 + -0.0026 × 1,824 + 2 × 0.0969)
= Exp(5.6785)
= $292.51
Bottom border of price channel:
Exp(Y1,255)
= Exp(a + b × X1,255 – 2 × s)
= Exp(a + b × 1,824 – 2 × s)
= Exp(10.2210 + -0.0026 × 1,824 – 2 × 0.0969)
= Exp(5.2909)
= $198.52
