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 HCA 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 16, 2024
End date: February 9, 2026

a = 3.8771

b = 0.0013

s = 0.0421

Annual growth rate:

Exp(365 × b) – 1
= Exp(365 × 0.0013) – 1
= 59.77%

Price channel spread:

Exp(4 × s) – 1
= Exp(4 × 0.0421) – 1
= 18.34%

Exp(Y968)
= Exp(a + b × X968 + 2 × s)
= Exp(a + b × 1,405 + 2 × s)
= Exp(3.8771 + 0.0013 × 1,405 + 2 × 0.0421)
= Exp(5.7649)
= $318.90

Bottom border of price channel:

Exp(Y968)
= Exp(a + b × X968 – 2 × s)
