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 SYK 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 8, 2022
End date: July 21, 2023

a = 4.1583

b = 0.0012

s = 0.0433

Annual growth rate:

Exp(365 × b) – 1
= Exp(365 × 0.0012) – 1
= 53.08%

Price channel spread:

Exp(4 × s) – 1
= Exp(4 × 0.0433) – 1
= 18.93%

Top border of price channel:

Exp(Y641)
= Exp(a + b × X641 + 2 × s)
= Exp(a + b × 931 + 2 × s)
= Exp(4.1583 + 0.0012 × 931 + 2 × 0.0433)
= Exp(5.3311)
= $206.67

Bottom border of price channel:

Exp(Y641)
= Exp(a + b × X641 – 2 × s)
= Exp(a + b × 931 – 2 × s)
= Exp(4.1583 + 0.0012 × 931 – 2 × 0.0433)
= Exp(5.1578)
= $173.78

Top border of price channel:

Exp(Y921)
= Exp(a + b × X921 + 2 × s)
= Exp(a + b × 1,339 + 2 × s)
= Exp(4.1583 + 0.0012 × 1,339 + 2 × 0.0433)
= Exp(5.8071)
= $332.65

Bottom border of price channel:

Exp(Y921)
= Exp(a + b × X921 – 2 × s)
= Exp(a + b × 1,339 – 2 × s)
= Exp(4.1583 + 0.0012 × 1,339 – 2 × 0.0433)
= Exp(5.6337)
