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: December 10, 2024

a = 5.2544

b = -0.0003

s = 0.1312

Annual growth rate:

Exp(365 × b) – 1
= Exp(365 × -0.0003) – 1
= -10.61%

Price channel spread:

Exp(4 × s) – 1
= Exp(4 × 0.1312) – 1
= 69.01%

June 24, 2021 calculations

Top border of price channel:

Exp(Y311)
= Exp(a + b × X311 + 2 × s)
= Exp(a + b × 450 + 2 × s)
= Exp(5.2544 + -0.0003 × 450 + 2 × 0.1312)
= Exp(5.3785)
= $216.70

Bottom border of price channel:

Exp(Y311)
= Exp(a + b × X311 – 2 × s)
= Exp(a + b × 450 – 2 × s)
= Exp(5.2544 + -0.0003 × 450 – 2 × 0.1312)
= Exp(4.8538)
= $128.22

December 10, 2024 calculations

Top border of price channel:

Exp(Y1,182)
= Exp(a + b × X1,182 + 2 × s)
= Exp(a + b × 1,715 + 2 × s)
= Exp(5.2544 + -0.0003 × 1,715 + 2 × 0.1312)
= Exp(4.9898)
= $146.91

Bottom border of price channel:

Exp(Y1,182)
= Exp(a + b × X1,182 – 2 × s)
= Exp(a + b × 1,715 – 2 × s)
= Exp(5.2544 + -0.0003 × 1,715 – 2 × 0.1312)
= Exp(4.4650)
= $86.92

a = 2.1343

b = 0.0016

s = 0.0660

Annual growth rate:

Exp(365 × b) – 1
= Exp(365 × 0.0016) – 1
= 77.07%

Price channel spread:

Exp(4 × s) – 1

Top border of price channel:

Exp(Y1,091)
= Exp(a + b × X1,091 + 2 × s)
= Exp(a + b × 1,584 + 2 × s)
= Exp(2.1343 + 0.0016 × 1,584 + 2 × 0.0660)
= Exp(4.7459)
= $115.11

Bottom border of price channel:
