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 SRE 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: November 8, 2024
End date: March 31, 2025

a = 8.1148

b = -0.0021

s = 0.0449

Annual growth rate:

Exp(365 × b) – 1
= Exp(365 × -0.0021) – 1
= -53.85%

Price channel spread:

Exp(4 × s) – 1
= Exp(4 × 0.0449) – 1
= 19.67%

Top border of price channel:

Exp(Y1,160)
= Exp(a + b × X1,160 + 2 × s)
= Exp(a + b × 1,682 + 2 × s)
= Exp(8.1148 + -0.0021 × 1,682 + 2 × 0.0449)
= Exp(4.6417)
= $103.72

Bottom border of price channel:

Exp(Y1,160)
= Exp(a + b × X1,160 – 2 × s)
= Exp(a + b × 1,682 – 2 × s)
= Exp(8.1148 + -0.0021 × 1,682 – 2 × 0.0449)
= Exp(4.4621)
= $86.67

Top border of price channel:

Exp(Y1,255)
= Exp(a + b × X1,255 + 2 × s)
= Exp(a + b × 1,825 + 2 × s)
= Exp(8.1148 + -0.0021 × 1,825 + 2 × 0.0449)
= Exp(4.3387)
= $76.61

Bottom border of price channel:

Exp(Y1,255)
= Exp(a + b × X1,255 – 2 × s)
= Exp(a + b × 1,825 – 2 × s)
