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 FUL 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: March 25, 2021
End date: November 13, 2023

a = 4.1387

b = 0.0001

s = 0.0667

Annual growth rate:

Exp(365 × b) – 1
= Exp(365 × 0.0001) – 1
= 2.03%

Price channel spread:

Exp(4 × s) – 1
= Exp(4 × 0.0667) – 1
= 30.55%

Top border of price channel:

Exp(Y473)
= Exp(a + b × X473 + 2 × s)
= Exp(a + b × 686 + 2 × s)
= Exp(4.1387 + 0.0001 × 686 + 2 × 0.0667)
= Exp(4.3098)
= $74.43

Bottom border of price channel:

Exp(Y473)
= Exp(a + b × X473 – 2 × s)
= Exp(a + b × 686 – 2 × s)
= Exp(4.1387 + 0.0001 × 686 – 2 × 0.0667)
= Exp(4.0432)
= $57.01

Top border of price channel:

Exp(Y1,137)
= Exp(a + b × X1,137 + 2 × s)
= Exp(a + b × 1,649 + 2 × s)
= Exp(4.1387 + 0.0001 × 1,649 + 2 × 0.0667)
= Exp(4.3629)
= $78.48

Bottom border of price channel:

Exp(Y1,137)
= Exp(a + b × X1,137 – 2 × s)
= Exp(a + b × 1,649 – 2 × s)
= Exp(4.1387 + 0.0001 × 1,649 – 2 × 0.0667)
= Exp(4.0963)
= $60.12

a = 3.3050

b = 0.0006

s = 0.0408

Annual growth rate:

Exp(365 × b) – 1
= Exp(365 × 0.0006) – 1
