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 AAPL 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

a = 1.9590
b = 0.0020
s = 0.0262
Annual growth rate:
Exp(365 × b) – 1
= Exp(365 × 0.0020) – 1
= 108.55%
Price channel spread:
Exp(4 × s) – 1
= Exp(4 × 0.0262) – 1
= 11.03%

= Exp(1.9590 + 0.0020 × 1,635 + 2 × 0.0262)
= Exp(5.3037)
= $201.07
Bottom border of price channel:
Exp(Y1,125)
= Exp(a + b × X1,125 – 2 × s)
= Exp(a + b × 1,635 – 2 × s)
= Exp(1.9590 + 0.0020 × 1,635 – 2 × 0.0262)
= Exp(5.1990)
= $181.10
