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 CDNS 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: January 18, 2024
End date: March 28, 2025

a = 5.9973

b = -0.0002

s = 0.0716

Annual growth rate:

Exp(365 × b) – 1
= Exp(365 × -0.0002) – 1
= -7.35%

Price channel spread:

Exp(4 × s) – 1
= Exp(4 × 0.0716) – 1
= 33.16%

Top border of price channel:

Exp(Y956)
= Exp(a + b × X956 + 2 × s)
= Exp(a + b × 1,388 + 2 × s)
= Exp(5.9973 + -0.0002 × 1,388 + 2 × 0.0716)
= Exp(5.8501)
= $347.28

Bottom border of price channel:

Exp(Y956)
= Exp(a + b × X956 – 2 × s)
= Exp(a + b × 1,388 – 2 × s)
= Exp(5.9973 + -0.0002 × 1,388 – 2 × 0.0716)
= Exp(5.5637)
= $260.80

Top border of price channel:

Exp(Y1,255)
= Exp(a + b × X1,255 + 2 × s)
= Exp(a + b × 1,823 + 2 × s)
= Exp(5.9973 + -0.0002 × 1,823 + 2 × 0.0716)
= Exp(5.7591)
= $317.07

Bottom border of price channel:

Exp(Y1,255)
= Exp(a + b × X1,255 – 2 × s)
= Exp(a + b × 1,823 – 2 × s)
= Exp(5.9973 + -0.0002 × 1,823 – 2 × 0.0716)
= Exp(5.4727)
= $238.11
