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 COTY 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 22, 2024
End date: December 26, 2025

a = 4.8211

b = -0.0020

s = 0.0670

Annual growth rate:

Exp(365 × b) – 1
= Exp(365 × -0.0020) – 1
= -51.41%

Price channel spread:

Exp(4 × s) – 1
= Exp(4 × 0.0670) – 1
= 30.71%

Top border of price channel:

Exp(Y770)
= Exp(a + b × X770 + 2 × s)
= Exp(a + b × 1,120 + 2 × s)
= Exp(4.8211 + -0.0020 × 1,120 + 2 × 0.0670)
= Exp(2.7405)
= $15.50

Bottom border of price channel:

Exp(Y770)
= Exp(a + b × X770 – 2 × s)
= Exp(a + b × 1,120 – 2 × s)
= Exp(4.8211 + -0.0020 × 1,120 – 2 × 0.0670)
= Exp(2.4727)
= $11.85
