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 S&P 500 Index
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

a = 7.6103
b = 0.0006
s = 0.0308
Annual growth rate:
Exp(365 × b) – 1
= Exp(365 × 0.0006) – 1
= 22.25%
Price channel spread:
Exp(4 × s) – 1
= Exp(4 × 0.0308) – 1
= 13.09%

= 3,927.42
Bottom border of price channel:
Exp(Y756)
= Exp(a + b × X756 – 2 × s)
= Exp(a + b × 1,097 – 2 × s)
= Exp(7.6103 + 0.0006 × 1,097 – 2 × 0.0308)
= Exp(8.1527)
= 3,472.74
