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 GOOGL 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 = 3.7007

b = 0.0009

s = 0.0686

Annual growth rate:

Exp(365 × b) – 1
= Exp(365 × 0.0009) – 1
= 38.59%

Price channel spread:

Exp(4 × s) – 1
= Exp(4 × 0.0686) – 1
= 31.58%

Top border of price channel:

Exp(Y623)
= Exp(a + b × X623 + 2 × s)
= Exp(a + b × 903 + 2 × s)
= Exp(3.7007 + 0.0009 × 903 + 2 × 0.0686)
= Exp(4.6452)
= $104.09

Bottom border of price channel:

Exp(Y623)
= Exp(a + b × X623 – 2 × s)
= Exp(a + b × 903 – 2 × s)
= Exp(3.7007 + 0.0009 × 903 – 2 × 0.0686)
= Exp(4.3707)
= $79.10
