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 3, 2022
End date: March 7, 2025

a = 4.8156

b = 0.0007

s = 0.0613

Annual growth rate:

Exp(365 × b) – 1
= Exp(365 × 0.0007) – 1
= 27.60%

Price channel spread:

Exp(4 × s) – 1
= Exp(4 × 0.0613) – 1
= 27.76%

Top border of price channel:

Exp(Y531)
= Exp(a + b × X531 + 2 × s)
= Exp(a + b × 767 + 2 × s)
= Exp(4.8156 + 0.0007 × 767 + 2 × 0.0613)
= Exp(5.4503)
= $232.82

Bottom border of price channel:

Exp(Y531)
= Exp(a + b × X531 – 2 × s)
= Exp(a + b × 767 – 2 × s)
= Exp(4.8156 + 0.0007 × 767 – 2 × 0.0613)
= Exp(5.2053)
= $182.23

= Exp(6.1234)
= $456.42

Bottom border of price channel:

Exp(Y1,222)
= Exp(a + b × X1,222 – 2 × s)
= Exp(a + b × 1,775 – 2 × s)
