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: December 14, 2023
End date: November 20, 2024

a = 4.8220

b = -0.0015

s = 0.0550

Annual growth rate:

Exp(365 × b) – 1
= Exp(365 × -0.0015) – 1
= -42.21%

Price channel spread:

Exp(4 × s) – 1
= Exp(4 × 0.0550) – 1
= 24.58%

Top border of price channel:

Exp(Y1,022)
= Exp(a + b × X1,022 + 2 × s)
= Exp(a + b × 1,484 + 2 × s)
= Exp(4.8220 + -0.0015 × 1,484 + 2 × 0.0550)
= Exp(2.7024)
= $14.92

Bottom border of price channel:

Exp(Y1,022)
= Exp(a + b × X1,022 – 2 × s)
= Exp(a + b × 1,484 – 2 × s)
= Exp(4.8220 + -0.0015 × 1,484 – 2 × 0.0550)
= Exp(2.4826)
= $11.97

Top border of price channel:

Exp(Y1,257)
= Exp(a + b × X1,257 + 2 × s)
= Exp(a + b × 1,826 + 2 × s)
= Exp(4.8220 + -0.0015 × 1,826 + 2 × 0.0550)
= Exp(2.1886)
= $8.92

Bottom border of price channel:

Exp(Y1,257)
= Exp(a + b × X1,257 – 2 × s)
= Exp(a + b × 1,826 – 2 × s)
= Exp(4.8220 + -0.0015 × 1,826 – 2 × 0.0550)
= Exp(1.9688)
= $7.16
