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 PLNT 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 16, 2024
End date: July 25, 2024

a = -0.8578

b = 0.0029

s = 0.0319

Annual growth rate:

Exp(365 × b) – 1
= Exp(365 × 0.0029) – 1
= 183.49%

Price channel spread:

Exp(4 × s) – 1
= Exp(4 × 0.0319) – 1
= 13.60%

Top border of price channel:

Exp(Y1,188)
= Exp(a + b × X1,188 + 2 × s)
= Exp(a + b × 1,726 + 2 × s)
= Exp(-0.8578 + 0.0029 × 1,726 + 2 × 0.0319)
= Exp(4.1334)
= $62.39

Bottom border of price channel:

Exp(Y1,188)
= Exp(a + b × X1,188 – 2 × s)
= Exp(a + b × 1,726 – 2 × s)
= Exp(-0.8578 + 0.0029 × 1,726 – 2 × 0.0319)
= Exp(4.0058)
= $54.92
