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 PRFT 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: August 5, 2021
End date: May 3, 2024

a = 5.4774

b = -0.0008

s = 0.1305

Annual growth rate:

Exp(365 × b) – 1
= Exp(365 × -0.0008) – 1
= -26.01%

Price channel spread:

Exp(4 × s) – 1
= Exp(4 × 0.1305) – 1
= 68.54%

Top border of price channel:

Exp(Y565)
= Exp(a + b × X565 + 2 × s)
= Exp(a + b × 819 + 2 × s)
= Exp(5.4774 + -0.0008 × 819 + 2 × 0.1305)
= Exp(5.0625)
= $157.99

Bottom border of price channel:

Exp(Y565)
= Exp(a + b × X565 – 2 × s)
= Exp(a + b × 819 – 2 × s)
= Exp(5.4774 + -0.0008 × 819 – 2 × 0.1305)
= Exp(4.5405)
= $93.74

May 3, 2024 calculations

Top border of price channel:

Exp(Y1,255)
= Exp(a + b × X1,255 + 2 × s)
= Exp(a + b × 1,821 + 2 × s)
= Exp(5.4774 + -0.0008 × 1,821 + 2 × 0.1305)
= Exp(4.2356)
= $69.10

Bottom border of price channel:

Exp(Y1,255)
= Exp(a + b × X1,255 – 2 × s)
= Exp(a + b × 1,821 – 2 × s)
= Exp(5.4774 + -0.0008 × 1,821 – 2 × 0.1305)
= Exp(3.7136)
= $41.00

a = 4.7790

b = -0.0004

s = 0.1180

Annual growth rate:

Exp(365 × b) – 1
= Exp(365 × -0.0004) – 1
= -12.95%

Price channel spread:

Exp(4 × s) – 1
= Exp(4 × 0.1180) – 1
= 60.34%

Top border of price channel:

Exp(Y829)
= Exp(a + b × X829 + 2 × s)
= Exp(a + b × 1,202 + 2 × s)
= Exp(4.7790 + -0.0004 × 1,202 + 2 × 0.1180)
= Exp(4.5581)
= $95.40

Bottom border of price channel:

Exp(Y829)
