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: November 3, 2025

a = 6.0171

b = -0.0006

s = 0.0363

Annual growth rate:

Exp(365 × b) – 1
= Exp(365 × -0.0006) – 1
= -19.14%

Price channel spread:

Exp(4 × s) – 1
= Exp(4 × 0.0363) – 1
= 15.63%

Top border of price channel:

Exp(Y934)
= Exp(a + b × X934 + 2 × s)
= Exp(a + b × 1,359 + 2 × s)
= Exp(6.0171 + -0.0006 × 1,359 + 2 × 0.0363)
= Exp(5.2989)
= $200.11

Bottom border of price channel:

Exp(Y934)
= Exp(a + b × X934 – 2 × s)
= Exp(a + b × 1,359 – 2 × s)
= Exp(6.0171 + -0.0006 × 1,359 – 2 × 0.0363)
= Exp(5.1536)
= $173.06

Top border of price channel:

Exp(Y1,246)
= Exp(a + b × X1,246 + 2 × s)
= Exp(a + b × 1,813 + 2 × s)
= Exp(6.0171 + -0.0006 × 1,813 + 2 × 0.0363)
= Exp(5.0347)
= $153.65

Bottom border of price channel:

Exp(Y1,246)
= Exp(a + b × X1,246 – 2 × s)
= Exp(a + b × 1,813 – 2 × s)
= Exp(6.0171 + -0.0006 × 1,813 – 2 × 0.0363)
= Exp(4.8895)
= $132.88
