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: May 7, 2024

a = 5.3075

b = -0.0003

s = 0.1403

Annual growth rate:

Exp(365 × b) – 1
= Exp(365 × -0.0003) – 1
= -9.26%

Price channel spread:

Exp(4 × s) – 1
= Exp(4 × 0.1403) – 1
= 75.30%

June 24, 2021 calculations

Top border of price channel:

Exp(Y537)
= Exp(a + b × X537 + 2 × s)
= Exp(a + b × 778 + 2 × s)
= Exp(5.3075 + -0.0003 × 778 + 2 × 0.1403)
= Exp(5.3810)
= $217.23

Bottom border of price channel:

Exp(Y537)
= Exp(a + b × X537 – 2 × s)
= Exp(a + b × 778 – 2 × s)
= Exp(5.3075 + -0.0003 × 778 – 2 × 0.1403)
= Exp(4.8196)
= $123.92

Top border of price channel:

Exp(Y1,258)
= Exp(a + b × X1,258 + 2 × s)
= Exp(a + b × 1,826 + 2 × s)
= Exp(5.3075 + -0.0003 × 1,826 + 2 × 0.1403)
= Exp(5.1019)
= $164.33

Bottom border of price channel:

Exp(Y1,258)
= Exp(a + b × X1,258 – 2 × s)
= Exp(a + b × 1,826 – 2 × s)
= Exp(5.3075 + -0.0003 × 1,826 – 2 × 0.1403)
= Exp(4.5406)
= $93.74
