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 THO 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: March 28, 2025
End date: September 16, 2025

a = -0.3682

b = 0.0029

s = 0.0400

Annual growth rate:

Exp(365 × b) – 1
= Exp(365 × 0.0029) – 1
= 183.45%

Price channel spread:

Exp(4 × s) – 1
= Exp(4 × 0.0400) – 1
= 17.35%

Top border of price channel:

Exp(Y1,105)
= Exp(a + b × X1,105 + 2 × s)
= Exp(a + b × 1,607 + 2 × s)
= Exp(-0.3682 + 0.0029 × 1,607 + 2 × 0.0400)
= Exp(4.2989)
= $73.62

Bottom border of price channel:

Exp(Y1,105)
= Exp(a + b × X1,105 – 2 × s)
= Exp(a + b × 1,607 – 2 × s)
= Exp(-0.3682 + 0.0029 × 1,607 – 2 × 0.0400)
= Exp(4.1389)
= $62.73

Top border of price channel:

Exp(Y1,222)
= Exp(a + b × X1,222 + 2 × s)
= Exp(a + b × 1,779 + 2 × s)
= Exp(-0.3682 + 0.0029 × 1,779 + 2 × 0.0400)
= Exp(4.7899)
= $120.29

Bottom border of price channel:

Exp(Y1,222)
= Exp(a + b × X1,222 – 2 × s)
= Exp(a + b × 1,779 – 2 × s)
