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 ACIW 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: June 14, 2023
End date: February 10, 2025

a = 0.8956

b = 0.0018

s = 0.0758

Annual growth rate:

Exp(365 × b) – 1
= Exp(365 × 0.0018) – 1
= 92.73%

Price channel spread:

Exp(4 × s) – 1
= Exp(4 × 0.0758) – 1
= 35.41%

June 14, 2023 calculations

Top border of price channel:

Exp(Y806)
= Exp(a + b × X806 + 2 × s)
= Exp(a + b × 1,169 + 2 × s)
= Exp(0.8956 + 0.0018 × 1,169 + 2 × 0.0758)
= Exp(3.1485)
= $23.30

Bottom border of price channel:

Exp(Y806)
= Exp(a + b × X806 – 2 × s)
= Exp(a + b × 1,169 – 2 × s)
= Exp(0.8956 + 0.0018 × 1,169 – 2 × 0.0758)
= Exp(2.8454)
= $17.21

February 10, 2025 calculations

Top border of price channel:

Exp(Y1,221)
= Exp(a + b × X1,221 + 2 × s)
= Exp(a + b × 1,776 + 2 × s)
= Exp(0.8956 + 0.0018 × 1,776 + 2 × 0.0758)
= Exp(4.2396)
= $69.38

Bottom border of price channel:

Exp(Y1,221)
= Exp(a + b × X1,221 – 2 × s)
= Exp(a + b × 1,776 – 2 × s)
= Exp(0.8956 + 0.0018 × 1,776 – 2 × 0.0758)
= Exp(3.9365)
= $51.24

Description

  • The primary trend is increasing.

a = 4.8999

b = -0.0005

s = 0.0291

Annual growth rate:

Exp(365 × b) – 1
= Exp(365 × -0.0005) – 1
= -17.41%

Price channel spread:

Exp(4 × s) – 1
= Exp(4 × 0.0291) – 1
= 12.34%
