### 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 SLAB 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: June 24, 2021

End date: July 19, 2024

a = 5.2962

b = -0.0003

s = 0.1365

Annual growth rate:

Exp(365 × b) – 1

= Exp(365 × -0.0003) – 1

= -9.53%

Price channel spread:

Exp(4 × s) – 1

= Exp(4 × 0.1365) – 1

= 72.60%

#### June 24, 2021 calculations

Top border of price channel:

Exp(Y_{486})

= Exp(a + b × X_{486} + 2 × s)

= Exp(a + b × 703 + 2 × s)

= Exp(5.2962 + -0.0003 × 703 + 2 × 0.1365)

= Exp(5.3762)

= $216.21

Bottom border of price channel:

Exp(Y_{486})

= Exp(a + b × X_{486} – 2 × s)

= Exp(a + b × 703 – 2 × s)

= Exp(5.2962 + -0.0003 × 703 – 2 × 0.1365)

= Exp(4.8304)

= $125.26

#### July 19, 2024 calculations

Top border of price channel:

Exp(Y_{1,257})

= Exp(a + b × X_{1,257} + 2 × s)

= Exp(a + b × 1,824 + 2 × s)

= Exp(5.2962 + -0.0003 × 1,824 + 2 × 0.1365)

= Exp(5.0686)

= $158.95

Bottom border of price channel:

Exp(Y_{1,257})

= Exp(a + b × X_{1,257} – 2 × s)

= Exp(a + b × 1,824 – 2 × s)

= Exp(5.2962 + -0.0003 × 1,824 – 2 × 0.1365)

= Exp(4.5228)

= $92.09

#### Description

- The primary trend is decreasing.
