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 CHD 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 31, 2022
End date: July 12, 2024

a = 3.8541

b = 0.0005

s = 0.0475

Annual growth rate:

Exp(365 × b) – 1
= Exp(365 × 0.0005) – 1
= 21.75%

Price channel spread:

Exp(4 × s) – 1
= Exp(4 × 0.0475) – 1
= 20.94%

Top border of price channel:

Exp(Y589)
= Exp(a + b × X589 + 2 × s)
= Exp(a + b × 853 + 2 × s)
= Exp(3.8541 + 0.0005 × 853 + 2 × 0.0475)
= Exp(4.4091)
= $82.20

Bottom border of price channel:

Exp(Y589)
= Exp(a + b × X589 – 2 × s)
= Exp(a + b × 853 – 2 × s)
= Exp(3.8541 + 0.0005 × 853 – 2 × 0.0475)
= Exp(4.2190)
= $67.96

Top border of price channel:

Exp(Y1,056)
= Exp(a + b × X1,056 + 2 × s)
= Exp(a + b × 1,534 + 2 × s)
= Exp(3.8541 + 0.0005 × 1,534 + 2 × 0.0475)
= Exp(4.7763)
= $118.66

Bottom border of price channel:

Exp(Y1,056)
= Exp(a + b × X1,056 – 2 × s)
= Exp(a + b × 1,534 – 2 × s)
= Exp(3.8541 + 0.0005 × 1,534 – 2 × 0.0475)
= Exp(4.5862)
= $98.12

March 31, 2023 calculations

Top border of price channel:

Exp(Y735)
= Exp(a + b × X735 + 2 × s)
= Exp(a + b × 1,065 + 2 × s)
= Exp(4.2339 + 0.0003 × 1,065 + 2 × 0.0379)
= Exp(4.5770)
= $97.22

Bottom border of price channel:
