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 CNC 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 10, 2021
End date: November 8, 2023

a = 4.8252

b = -0.0004

s = 0.0762

Annual growth rate:

Exp(365 × b) – 1
= Exp(365 × -0.0004) – 1
= -14.96%

Price channel spread:

Exp(4 × s) – 1
= Exp(4 × 0.0762) – 1
= 35.62%

Top border of price channel:

Exp(Y517)
= Exp(a + b × X517 + 2 × s)
= Exp(a + b × 750 + 2 × s)
= Exp(4.8252 + -0.0004 × 750 + 2 × 0.0762)
= Exp(4.6447)
= $104.03

Bottom border of price channel:

Exp(Y517)
= Exp(a + b × X517 – 2 × s)
= Exp(a + b × 750 – 2 × s)
= Exp(4.8252 + -0.0004 × 750 – 2 × 0.0762)
= Exp(4.3400)
= $76.71

Exp(Y997)
= Exp(a + b × X997 + 2 × s)
= Exp(a + b × 1,448 + 2 × s)
= Exp(4.8252 + -0.0004 × 1,448 + 2 × 0.0762)
= Exp(4.3349)
= $76.31

Bottom border of price channel:

Exp(Y997)
= Exp(a + b × X997 – 2 × s)
= Exp(a + b × 1,448 – 2 × s)
= Exp(4.8252 + -0.0004 × 1,448 – 2 × 0.0762)
= Exp(4.0302)
= $56.27
