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 Dow Jones Industrial Average (DJIA)
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: March 8, 2021

a = 10.4594

b = 0.0000

s = 0.0430

Annual growth rate:

Exp(365 × b) – 1
= Exp(365 × 0.0000) – 1
= -1.20%

Price channel spread:

Exp(4 × s) – 1
= Exp(4 × 0.0430) – 1
= 18.79%

Top border of price channel:

Exp(Y367)
= Exp(a + b × X367 + 2 × s)
= Exp(a + b × 535 + 2 × s)
= Exp(10.4594 + 0.0000 × 535 + 2 × 0.0430)
= Exp(10.5277)
= 37,334.88

Bottom border of price channel:

Exp(Y367)
= Exp(a + b × X367 – 2 × s)
= Exp(a + b × 535 – 2 × s)
= Exp(10.4594 + 0.0000 × 535 – 2 × 0.0430)
= Exp(10.3555)
= 31,429.72

Top border of price channel:

Exp(Y1,045)
= Exp(a + b × X1,045 + 2 × s)
= Exp(a + b × 1,516 + 2 × s)
= Exp(10.4594 + 0.0000 × 1,516 + 2 × 0.0430)
= Exp(10.4951)
= 36,138.04

Bottom border of price channel:

Exp(Y1,045)
= Exp(a + b × X1,045 – 2 × s)
= Exp(a + b × 1,516 – 2 × s)
= Exp(10.4594 + 0.0000 × 1,516 – 2 × 0.0430)
= Exp(10.3229)
