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 SPGI 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: September 21, 2022
End date: November 19, 2024

a = 5.1123

b = 0.0006

s = 0.0520

Annual growth rate:

Exp(365 × b) – 1
= Exp(365 × 0.0006) – 1
= 24.93%

Price channel spread:

Exp(4 × s) – 1
= Exp(4 × 0.0520) – 1
= 23.10%

September 21, 2022 calculations

Top border of price channel:

Exp(Y713)
= Exp(a + b × X713 + 2 × s)
= Exp(a + b × 1,036 + 2 × s)
= Exp(5.1123 + 0.0006 × 1,036 + 2 × 0.0520)
= Exp(5.8480)
= $346.56

Bottom border of price channel:

Exp(Y713)
= Exp(a + b × X713 – 2 × s)
= Exp(a + b × 1,036 – 2 × s)
= Exp(5.1123 + 0.0006 × 1,036 – 2 × 0.0520)
= Exp(5.6402)
= $281.52

= Exp(a + b × X1,257 + 2 × s)
= Exp(a + b × 1,826 + 2 × s)
= Exp(5.1123 + 0.0006 × 1,826 + 2 × 0.0520)
= Exp(6.3298)
= $561.06

Bottom border of price channel:

Exp(Y1,257)
= Exp(a + b × X1,257 – 2 × s)
= Exp(a + b × 1,826 – 2 × s)
= Exp(5.1123 + 0.0006 × 1,826 – 2 × 0.0520)
= Exp(6.1220)
= $455.77
