### 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 TSLA 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: December 7, 2020
End date: June 18, 2024

a = 5.7468

b = -0.0003

s = 0.2166

Annual growth rate:

Exp(365 × b) – 1
= Exp(365 × -0.0003) – 1
= -8.91%

Exp(4 × s) – 1
= Exp(4 × 0.2166) – 1
= 137.86%

#### December 7, 2020 calculations

Top border of price channel:

Exp(Y370)
= Exp(a + b × X370 + 2 × s)
= Exp(a + b × 536 + 2 × s)
= Exp(5.7468 + -0.0003 × 536 + 2 × 0.2166)
= Exp(6.0430)
= \$421.17

Bottom border of price channel:

Exp(Y370)
= Exp(a + b × X370 – 2 × s)
= Exp(a + b × 536 – 2 × s)
= Exp(5.7468 + -0.0003 × 536 – 2 × 0.2166)
= Exp(5.1765)
= \$177.06

#### June 18, 2024 calculations

Top border of price channel:

Exp(Y1,257)
= Exp(a + b × X1,257 + 2 × s)
= Exp(a + b × 1,825 + 2 × s)
= Exp(5.7468 + -0.0003 × 1,825 + 2 × 0.2166)
= Exp(5.7135)
= \$302.92

Bottom border of price channel:

Exp(Y1,257)
= Exp(a + b × X1,257 – 2 × s)
= Exp(a + b × 1,825 – 2 × s)
= Exp(5.7468 + -0.0003 × 1,825 – 2 × 0.2166)
= Exp(4.8470)
= \$127.35

#### Description

• The primary trend is decreasing.

### Secondary Trend

Start date: June 13, 2023
End date: June 18, 2024

a = 7.7220

b = -0.0014

s = 0.0834

Annual growth rate:

Exp(365 × b) – 1
= Exp(365 × -0.0014) – 1
= -40.70%

Exp(4 × s) – 1
= Exp(4 × 0.0834) – 1
= 39.59%

#### June 13, 2023 calculations

Top border of price channel:

Exp(Y1,002)
= Exp(a + b × X1,002 + 2 × s)
= Exp(a + b × 1,454 + 2 × s)
= Exp(7.7220 + -0.0014 × 1,454 + 2 × 0.0834)
= Exp(5.8071)
= \$332.64

Bottom border of price channel:
