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 PLD 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 2, 2021
End date: April 28, 2025

a = 4.8785

b = -0.0001

s = 0.0975

Annual growth rate:

Exp(365 × b) – 1
= Exp(365 × -0.0001) – 1
= -3.60%

Price channel spread:

Exp(4 × s) – 1
= Exp(4 × 0.0975) – 1
= 47.72%

August 2, 2021 calculations

Top border of price channel:

Exp(Y317)
= Exp(a + b × X317 + 2 × s)
= Exp(a + b × 460 + 2 × s)
= Exp(4.8785 + -0.0001 × 460 + 2 × 0.0975)
= Exp(5.0273)
= $152.52

Bottom border of price channel:

Exp(Y317)
= Exp(a + b × X317 – 2 × s)
= Exp(a + b × 460 – 2 × s)
= Exp(4.8785 + -0.0001 × 460 – 2 × 0.0975)
= Exp(4.6372)
= $103.25

Top border of price channel:

Exp(Y1,255)
= Exp(a + b × X1,255 + 2 × s)
= Exp(a + b × 1,825 + 2 × s)
= Exp(4.8785 + -0.0001 × 1,825 + 2 × 0.0975)
= Exp(4.8901)
= $132.97

Bottom border of price channel:

Exp(Y1,255)
= Exp(a + b × X1,255 – 2 × s)
= Exp(a + b × 1,825 – 2 × s)
= Exp(4.8785 + -0.0001 × 1,825 – 2 × 0.0975)
= Exp(4.5000)
= $90.01
