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 ALTR 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 29, 2022
End date: March 26, 2025

a = 3.0609

b = 0.0009

s = 0.0895

Annual growth rate:

Exp(365 × b) – 1
= Exp(365 × 0.0009) – 1
= 40.58%

Price channel spread:

Exp(4 × s) – 1
= Exp(4 × 0.0895) – 1
= 43.06%

August 29, 2022 calculations

Top border of price channel:

Exp(Y607)
= Exp(a + b × X607 + 2 × s)
= Exp(a + b × 880 + 2 × s)
= Exp(3.0609 + 0.0009 × 880 + 2 × 0.0895)
= Exp(4.0611)
= $58.04

Bottom border of price channel:

Exp(Y607)
= Exp(a + b × X607 – 2 × s)
= Exp(a + b × 880 – 2 × s)
= Exp(3.0609 + 0.0009 × 880 – 2 × 0.0895)
= Exp(3.7030)
= $40.57

March 26, 2025 calculations

Top border of price channel:

Exp(Y1,252)
= Exp(a + b × X1,252 + 2 × s)
= Exp(a + b × 1,820 + 2 × s)
= Exp(3.0609 + 0.0009 × 1,820 + 2 × 0.0895)
= Exp(4.9384)
= $139.54

Bottom border of price channel:

Exp(Y1,252)
= Exp(a + b × X1,252 – 2 × s)
= Exp(a + b × 1,820 – 2 × s)
= Exp(3.0609 + 0.0009 × 1,820 – 2 × 0.0895)
= Exp(4.5802)
= $97.54

a = 4.3412

b = 0.0002

s = 0.0025

Annual growth rate:

Exp(365 × b) – 1
= Exp(365 × 0.0002) – 1
= 7.82%

Price channel spread:

Exp(4 × s) – 1
= Exp(4 × 0.0025) – 1
= 1.00%
