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 ZTS 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: August 6, 2024
End date: October 23, 2025

a = 6.0372

b = -0.0006

s = 0.0367

Annual growth rate:

Exp(365 × b) – 1
= Exp(365 × -0.0006) – 1
= -19.22%

Price channel spread:

Exp(4 × s) – 1
= Exp(4 × 0.0367) – 1
= 15.80%

Exp(Y949)
= Exp(a + b × X949 + 2 × s)
= Exp(a + b × 1,380 + 2 × s)
= Exp(6.0372 + -0.0006 × 1,380 + 2 × 0.0367)
= Exp(5.3035)
= $201.04

Bottom border of price channel:

Exp(Y949)
= Exp(a + b × X949 – 2 × s)
= Exp(a + b × 1,380 – 2 × s)
= Exp(6.0372 + -0.0006 × 1,380 – 2 × 0.0367)
