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 HCC 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: April 11, 2024
End date: March 31, 2025

a = 5.4899

b = -0.0008

s = 0.0863

Annual growth rate:

Exp(365 × b) – 1
= Exp(365 × -0.0008) – 1
= -26.59%

Price channel spread:

Exp(4 × s) – 1
= Exp(4 × 0.0863) – 1
= 41.23%

Top border of price channel:

Exp(Y1,013)
= Exp(a + b × X1,013 + 2 × s)
= Exp(a + b × 1,471 + 2 × s)
= Exp(5.4899 + -0.0008 × 1,471 + 2 × 0.0863)
= Exp(4.4169)
= $82.84

Bottom border of price channel:

Exp(Y1,013)
= Exp(a + b × X1,013 – 2 × s)
= Exp(a + b × 1,471 – 2 × s)
= Exp(5.4899 + -0.0008 × 1,471 – 2 × 0.0863)
= Exp(4.0716)
= $58.65

March 31, 2025 calculations

Top border of price channel:

Exp(Y1,255)
= Exp(a + b × X1,255 + 2 × s)
= Exp(a + b × 1,825 + 2 × s)
= Exp(5.4899 + -0.0008 × 1,825 + 2 × 0.0863)
= Exp(4.1171)
= $61.38

Bottom border of price channel:

Exp(Y1,255)
= Exp(a + b × X1,255 – 2 × s)
= Exp(a + b × 1,825 – 2 × s)
= Exp(5.4899 + -0.0008 × 1,825 – 2 × 0.0863)
= Exp(3.7719)
= $43.46
