### Linear Regression Model

Model equation:

Y_{i} = α + β × X_{i} + ε_{i}

Top border of price channel:

Exp(Y_{i}) = Exp(a + b × X_{i} + 2 × s)

Bottom border of price channel:

Exp(Y_{i}) = Exp(a + b × X_{i} – 2 × s)

where:

i - observation number

Y_{i} - natural logarithm of AMD price

X_{i} - time index, 1 day interval

σ - standard deviation of ε_{i}

a - estimator of α

b - estimator of β

s - estimator of σ

Exp() - calculates the exponent of e

### Primary Trend

Start date: September 22, 2022

End date: June 7, 2024

a = 2.0420

b = 0.0018

s = 0.1168

Annual growth rate:

Exp(365 × b) – 1

= Exp(365 × 0.0018) – 1

= 89.73%

Price channel spread:

Exp(4 × s) – 1

= Exp(4 × 0.1168) – 1

= 59.54%

#### September 22, 2022 calculations

Top border of price channel:

Exp(Y_{821})

= Exp(a + b × X_{821} + 2 × s)

= Exp(a + b × 1,190 + 2 × s)

= Exp(2.0420 + 0.0018 × 1,190 + 2 × 0.1168)

= Exp(4.3635)

= $78.53

Bottom border of price channel:

Exp(Y_{821})

= Exp(a + b × X_{821} – 2 × s)

= Exp(a + b × 1,190 – 2 × s)

= Exp(2.0420 + 0.0018 × 1,190 – 2 × 0.1168)

= Exp(3.8964)

= $49.22

#### June 7, 2024 calculations

Top border of price channel:

Exp(Y_{1,250})

= Exp(a + b × X_{1,250} + 2 × s)

= Exp(a + b × 1,814 + 2 × s)

= Exp(2.0420 + 0.0018 × 1,814 + 2 × 0.1168)

= Exp(5.4584)

= $234.71

Bottom border of price channel:

Exp(Y_{1,250})

= Exp(a + b × X_{1,250} – 2 × s)

= Exp(a + b × 1,814 – 2 × s)

= Exp(2.0420 + 0.0018 × 1,814 – 2 × 0.1168)

= Exp(4.9912)

= $147.12

#### Description

- The primary trend is increasing.
- The growth rate of the primary trend is 89.73% per annum.
