### 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 TSLA 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: December 7, 2020

End date: October 4, 2024

a = 5.6784

b = -0.0002

s = 0.2128

Annual growth rate:

Exp(365 × b) – 1

= Exp(365 × -0.0002) – 1

= -7.36%

Price channel spread:

Exp(4 × s) – 1

= Exp(4 × 0.2128) – 1

= 134.28%

#### December 7, 2020 calculations

Top border of price channel:

Exp(Y_{295})

= Exp(a + b × X_{295} + 2 × s)

= Exp(a + b × 427 + 2 × s)

= Exp(5.6784 + -0.0002 × 427 + 2 × 0.2128)

= Exp(6.0147)

= $409.39

Bottom border of price channel:

Exp(Y_{295})

= Exp(a + b × X_{295} – 2 × s)

= Exp(a + b × 427 – 2 × s)

= Exp(5.6784 + -0.0002 × 427 – 2 × 0.2128)

= Exp(5.1633)

= $174.75

#### October 4, 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(5.6784 + -0.0002 × 1,824 + 2 × 0.2128)

= Exp(5.7221)

= $305.54

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(5.6784 + -0.0002 × 1,824 – 2 × 0.2128)

= Exp(4.8707)

= $130.42

#### Description

- The primary trend is decreasing.
