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: January 27, 2025
End date: March 21, 2025
a = 15.8560
b = -0.0056
s = 0.0266
Annual growth rate:
Exp(365 × b) – 1
= Exp(365 × -0.0056) – 1
= -86.92%
Price channel spread:
Exp(4 × s) – 1
= Exp(4 × 0.0266) – 1
= 11.23%

Top border of price channel:
Exp(Y1,209)
= Exp(a + b × X1,209 + 2 × s)
= Exp(a + b × 1,760 + 2 × s)
= Exp(15.8560 + -0.0056 × 1,760 + 2 × 0.0266)
= Exp(6.1019)
= $446.70
Bottom border of price channel:
Exp(Y1,209)
= Exp(a + b × X1,209 – 2 × s)
= Exp(a + b × 1,760 – 2 × s)
= Exp(15.8560 + -0.0056 × 1,760 – 2 × 0.0266)
= Exp(5.9955)
= $401.61

Top border of price channel:
Exp(Y1,247)
= Exp(a + b × X1,247 + 2 × s)
= Exp(a + b × 1,813 + 2 × s)
= Exp(15.8560 + -0.0056 × 1,813 + 2 × 0.0266)
= Exp(5.8066)
= $332.47
Bottom border of price channel:
Exp(Y1,247)
= Exp(a + b × X1,247 – 2 × s)
= Exp(a + b × 1,813 – 2 × s)
= Exp(15.8560 + -0.0056 × 1,813 – 2 × 0.0266)
= Exp(5.7002)
= $298.91
