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 ITW 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


Primary Trend

Start date: April 5, 2022
End date: April 15, 2024

a = 4.8411

b = 0.0005

s = 0.0519

Annual growth rate:

Exp(365 × b) – 1
= Exp(365 × 0.0005) – 1
= 19.40%

Price channel spread:

Exp(4 × s) – 1
= Exp(4 × 0.0519) – 1
= 23.07%

April 5, 2022 calculations

Top border of price channel:

Exp(Y507)
= Exp(a + b × X507 + 2 × s)
= Exp(a + b × 734 + 2 × s)
= Exp(4.8411 + 0.0005 × 734 + 2 × 0.0519)
= Exp(5.3014)
= $200.63

Bottom border of price channel:

Exp(Y507)
= Exp(a + b × X507 – 2 × s)
= Exp(a + b × 734 – 2 × s)
= Exp(4.8411 + 0.0005 × 734 – 2 × 0.0519)
= Exp(5.0939)
= $163.02

April 15, 2024 calculations

Top border of price channel:

Exp(Y1,015)
= Exp(a + b × X1,015 + 2 × s)
= Exp(a + b × 1,475 + 2 × s)
= Exp(4.8411 + 0.0005 × 1,475 + 2 × 0.0519)
= Exp(5.6614)
= $287.55

Bottom border of price channel:

Exp(Y1,015)
= Exp(a + b × X1,015 – 2 × s)
= Exp(a + b × 1,475 – 2 × s)
= Exp(4.8411 + 0.0005 × 1,475 – 2 × 0.0519)
= Exp(5.4538)
= $233.65
