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 SUPN 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: August 12, 2022
End date: August 6, 2024

a = 4.0435

b = -0.0004

s = 0.0951

Annual growth rate:

Exp(365 × b) – 1
= Exp(365 × -0.0004) – 1
= -14.61%

Price channel spread:

Exp(4 × s) – 1
= Exp(4 × 0.0951) – 1
= 46.26%

August 12, 2022 calculations

Top border of price channel:

Exp(Y686)
= Exp(a + b × X686 + 2 × s)
= Exp(a + b × 996 + 2 × s)
= Exp(4.0435 + -0.0004 × 996 + 2 × 0.0951)
= Exp(3.8026)
= $44.82

Bottom border of price channel:

Exp(Y686)
= Exp(a + b × X686 – 2 × s)
= Exp(a + b × 996 – 2 × s)
= Exp(4.0435 + -0.0004 × 996 – 2 × 0.0951)
= Exp(3.4224)
= $30.64

August 6, 2024 calculations

Top border of price channel:

Exp(Y1,183)
= Exp(a + b × X1,183 + 2 × s)
= Exp(a + b × 1,721 + 2 × s)
= Exp(4.0435 + -0.0004 × 1,721 + 2 × 0.0951)
= Exp(3.4889)
= $32.75

Bottom border of price channel:

Exp(Y1,183)
= Exp(a + b × X1,183 – 2 × s)
= Exp(a + b × 1,721 – 2 × s)
= Exp(4.0435 + -0.0004 × 1,721 – 2 × 0.0951)
= Exp(3.1087)
= $22.39
