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 DG 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 22, 2022
End date: March 31, 2025

a = 6.6429

b = -0.0013

s = 0.1430

Annual growth rate:

Exp(365 × b) – 1
= Exp(365 × -0.0013) – 1
= -37.31%

Price channel spread:

Exp(4 × s) – 1
= Exp(4 × 0.1430) – 1
= 77.17%

June 22, 2022 calculations

Top border of price channel:

Exp(Y560)
= Exp(a + b × X560 + 2 × s)
= Exp(a + b × 812 + 2 × s)
= Exp(6.6429 + -0.0013 × 812 + 2 × 0.1430)
= Exp(5.8900)
= $361.41

Bottom border of price channel:

Exp(Y560)
= Exp(a + b × X560 – 2 × s)
= Exp(a + b × 812 – 2 × s)
= Exp(6.6429 + -0.0013 × 812 – 2 × 0.1430)
= Exp(5.3181)
= $203.99

March 31, 2025 calculations

Top border of price channel:

Exp(Y1,255)
= Exp(a + b × X1,255 + 2 × s)
= Exp(a + b × 1,825 + 2 × s)
= Exp(6.6429 + -0.0013 × 1,825 + 2 × 0.1430)
= Exp(4.5939)
= $98.88

Bottom border of price channel:

Exp(Y1,255)
= Exp(a + b × X1,255 – 2 × s)
= Exp(a + b × 1,825 – 2 × s)
= Exp(6.6429 + -0.0013 × 1,825 – 2 × 0.1430)
= Exp(4.0220)
= $55.81

Start date: January 14, 2025
End date: March 31, 2025

a = -0.4122

b = 0.0027

s = 0.0289

Annual growth rate:

Exp(365 × b) – 1
= Exp(365 × 0.0027) – 1
= 163.34%

Price channel spread:

Exp(4 × s) – 1
= Exp(4 × 0.0289) – 1
= 12.25%

Top border of price channel:

Exp(Y1,203)
= Exp(a + b × X1,203 + 2 × s)
= Exp(a + b × 1,749 + 2 × s)
= Exp(-0.4122 + 0.0027 × 1,749 + 2 × 0.0289)
= Exp(4.2853)
= $72.62

Bottom border of price channel:
