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 STE 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: April 9, 2021
End date: June 1, 2023

a = 5.4491

b = -0.0002

s = 0.0889

Annual growth rate:

Exp(365 × b) – 1
= Exp(365 × -0.0002) – 1
= -6.89%

Price channel spread:

Exp(4 × s) – 1
= Exp(4 × 0.0889) – 1
= 42.69%

Top border of price channel:

Exp(Y237)
= Exp(a + b × X237 + 2 × s)
= Exp(a + b × 344 + 2 × s)
= Exp(5.4491 + -0.0002 × 344 + 2 × 0.0889)
= Exp(5.5595)
= $259.70

Bottom border of price channel:

Exp(Y237)
= Exp(a + b × X237 – 2 × s)
= Exp(a + b × 344 – 2 × s)
= Exp(5.4491 + -0.0002 × 344 – 2 × 0.0889)
= Exp(5.2040)
= $182.00

Top border of price channel:

Exp(Y777)
= Exp(a + b × X777 + 2 × s)
= Exp(a + b × 1,127 + 2 × s)
= Exp(5.4491 + -0.0002 × 1,127 + 2 × 0.0889)
= Exp(5.4063)
= $222.81

Bottom border of price channel:

Exp(Y777)
= Exp(a + b × X777 – 2 × s)
= Exp(a + b × 1,127 – 2 × s)
= Exp(5.4491 + -0.0002 × 1,127 – 2 × 0.0889)
= Exp(5.0508)
= $156.14
