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 ABBV 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 = 4.7972

b = 0.0001

s = 0.0584

Annual growth rate:

Exp(365 × b) – 1
= Exp(365 × 0.0001) – 1
= 4.33%

Price channel spread:

Exp(4 × s) – 1
= Exp(4 × 0.0584) – 1
= 26.29%

Top border of price channel:

Exp(Y433)
= Exp(a + b × X433 + 2 × s)
= Exp(a + b × 625 + 2 × s)
= Exp(4.7972 + 0.0001 × 625 + 2 × 0.0584)
= Exp(4.9864)
= $146.41

Bottom border of price channel:

Exp(Y433)
= Exp(a + b × X433 – 2 × s)
= Exp(a + b × 625 – 2 × s)
= Exp(4.7972 + 0.0001 × 625 – 2 × 0.0584)
= Exp(4.7530)
= $115.93

Top border of price channel:

Exp(Y945)
= Exp(a + b × X945 + 2 × s)
= Exp(a + b × 1,369 + 2 × s)
= Exp(4.7972 + 0.0001 × 1,369 + 2 × 0.0584)
= Exp(5.0728)
= $159.61

Bottom border of price channel:

Exp(Y945)
= Exp(a + b × X945 – 2 × s)
= Exp(a + b × 1,369 – 2 × s)
= Exp(4.7972 + 0.0001 × 1,369 – 2 × 0.0584)
= Exp(4.8394)
= $126.39
