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: July 26, 2024
a = 5.1236
b = 0.0006
s = 0.0517
Annual growth rate:
Exp(365 × b) – 1
= Exp(365 × 0.0006) – 1
= 22.36%
Price channel spread:
Exp(4 × s) – 1
= Exp(4 × 0.0517) – 1
= 22.96%

Top border of price channel:
Exp(Y794)
= Exp(a + b × X794 + 2 × s)
= Exp(a + b × 1,150 + 2 × s)
= Exp(5.1236 + 0.0006 × 1,150 + 2 × 0.0517)
= Exp(5.8628)
= $351.70
Bottom border of price channel:
Exp(Y794)
= Exp(a + b × X794 – 2 × s)
= Exp(a + b × 1,150 – 2 × s)
= Exp(5.1236 + 0.0006 × 1,150 – 2 × 0.0517)
= Exp(5.6561)
= $286.03
