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 FSLR 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: May 22, 2024
End date: November 19, 2024

a = 8.1299

b = -0.0016

s = 0.0757

Annual growth rate:

Exp(365 × b) – 1
= Exp(365 × -0.0016) – 1
= -43.37%

Price channel spread:

Exp(4 × s) – 1
= Exp(4 × 0.0757) – 1
= 35.36%

May 22, 2024 calculations

Top border of price channel:

Exp(Y1,132)
= Exp(a + b × X1,132 + 2 × s)
= Exp(a + b × 1,645 + 2 × s)
= Exp(8.1299 + -0.0016 × 1,645 + 2 × 0.0757)
= Exp(5.7185)
= $304.45

Bottom border of price channel:

Exp(Y1,132)
= Exp(a + b × X1,132 – 2 × s)
= Exp(a + b × 1,645 – 2 × s)
= Exp(8.1299 + -0.0016 × 1,645 – 2 × 0.0757)
= Exp(5.4158)
= $224.92

November 19, 2024 calculations

Top border of price channel:

Exp(Y1,257)
= Exp(a + b × X1,257 + 2 × s)
= Exp(a + b × 1,826 + 2 × s)
= Exp(8.1299 + -0.0016 × 1,826 + 2 × 0.0757)
= Exp(5.4365)
= $229.65

Bottom border of price channel:

Exp(Y1,257)
= Exp(a + b × X1,257 – 2 × s)
= Exp(a + b × 1,826 – 2 × s)
= Exp(8.1299 + -0.0016 × 1,826 – 2 × 0.0757)
= Exp(5.1338)
= $169.66
