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 ADMA 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: September 7, 2021
End date: July 11, 2025

a = -0.8749

b = 0.0022

s = 0.2327

Annual growth rate:

Exp(365 × b) – 1
= Exp(365 × 0.0022) – 1
= 122.06%

Price channel spread:

Exp(4 × s) – 1
= Exp(4 × 0.2327) – 1
= 153.66%

September 7, 2021 calculations

Top border of price channel:

Exp(Y291)
= Exp(a + b × X291 + 2 × s)
= Exp(a + b × 421 + 2 × s)
= Exp(-0.8749 + 0.0022 × 421 + 2 × 0.2327)
= Exp(0.5107)
= $1.67

Bottom border of price channel:

Exp(Y291)
= Exp(a + b × X291 – 2 × s)
= Exp(a + b × 421 – 2 × s)
= Exp(-0.8749 + 0.0022 × 421 – 2 × 0.2327)
= Exp(-0.4202)
= $0.66

= Exp(a + b × X1,255 + 2 × s)
= Exp(a + b × 1,824 + 2 × s)
= Exp(-0.8749 + 0.0022 × 1,824 + 2 × 0.2327)
= Exp(3.5771)
= $35.77

Bottom border of price channel:

Exp(Y1,255)
= Exp(a + b × X1,255 – 2 × s)
= Exp(a + b × 1,824 – 2 × s)
= Exp(-0.8749 + 0.0022 × 1,824 – 2 × 0.2327)
= Exp(2.6463)
= $14.10
