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 SLAB 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 24, 2021
End date: January 2, 2025

a = 5.2589

b = -0.0003

s = 0.1310

Annual growth rate:

Exp(365 × b) – 1
= Exp(365 × -0.0003) – 1
= -10.31%

Price channel spread:

Exp(4 × s) – 1
= Exp(4 × 0.1310) – 1
= 68.86%

June 24, 2021 calculations

Top border of price channel:

Exp(Y341)
= Exp(a + b × X341 + 2 × s)
= Exp(a + b × 492 + 2 × s)
= Exp(5.2589 + -0.0003 × 492 + 2 × 0.1310)
= Exp(5.3742)
= $215.76

Bottom border of price channel:

Exp(Y341)
= Exp(a + b × X341 – 2 × s)
= Exp(a + b × 492 – 2 × s)
= Exp(5.2589 + -0.0003 × 492 – 2 × 0.1310)
= Exp(4.8503)
= $127.78

January 2, 2025 calculations

Top border of price channel:

Exp(Y1,227)
= Exp(a + b × X1,227 + 2 × s)
= Exp(a + b × 1,780 + 2 × s)
= Exp(5.2589 + -0.0003 × 1,780 + 2 × 0.1310)
= Exp(4.9903)
= $146.98

Bottom border of price channel:

Exp(Y1,227)
= Exp(a + b × X1,227 – 2 × s)
= Exp(a + b × 1,780 – 2 × s)
= Exp(5.2589 + -0.0003 × 1,780 – 2 × 0.1310)
= Exp(4.4664)
= $87.04
