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 20, 2022
End date: March 6, 2025
a = 5.2043
b = 0.0006
s = 0.0499
Annual growth rate:
Exp(365 × b) – 1
= Exp(365 × 0.0006) – 1
= 24.39%
Price channel spread:
Exp(4 × s) – 1
= Exp(4 × 0.0499) – 1
= 22.09%

Top border of price channel:
Exp(Y622)
= Exp(a + b × X622 + 2 × s)
= Exp(a + b × 902 + 2 × s)
= Exp(5.2043 + 0.0006 × 902 + 2 × 0.0499)
= Exp(5.8434)
= $344.94
Bottom border of price channel:
Exp(Y622)
= Exp(a + b × X622 – 2 × s)
= Exp(a + b × 902 – 2 × s)
= Exp(5.2043 + 0.0006 × 902 – 2 × 0.0499)
= Exp(5.6438)
= $282.53

Top border of price channel:
Exp(Y1,238)
= Exp(a + b × X1,238 + 2 × s)
= Exp(a + b × 1,800 + 2 × s)
= Exp(5.2043 + 0.0006 × 1,800 + 2 × 0.0499)
= Exp(6.3803)
= $590.08
Bottom border of price channel:
Exp(Y1,238)
= Exp(a + b × X1,238 – 2 × s)
= Exp(a + b × 1,800 – 2 × s)
= Exp(5.2043 + 0.0006 × 1,800 – 2 × 0.0499)
= Exp(6.1807)
= $483.32
