### 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 AMZN 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: November 2, 2022
End date: July 17, 2024

a = 2.8509

b = 0.0014

s = 0.0545

Annual growth rate:

Exp(365 × b) – 1
= Exp(365 × 0.0014) – 1
= 64.66%

Exp(4 × s) – 1
= Exp(4 × 0.0545) – 1
= 24.37%

#### November 2, 2022 calculations

Top border of price channel:

Exp(Y812)
= Exp(a + b × X812 + 2 × s)
= Exp(a + b × 1,176 + 2 × s)
= Exp(2.8509 + 0.0014 × 1,176 + 2 × 0.0545)
= Exp(4.5667)
= \$96.23

Bottom border of price channel:

Exp(Y812)
= Exp(a + b × X812 – 2 × s)
= Exp(a + b × 1,176 – 2 × s)
= Exp(2.8509 + 0.0014 × 1,176 – 2 × 0.0545)
= Exp(4.3487)
= \$77.37

#### July 17, 2024 calculations

Top border of price channel:

Exp(Y1,238)
= Exp(a + b × X1,238 + 2 × s)
= Exp(a + b × 1,799 + 2 × s)
= Exp(2.8509 + 0.0014 × 1,799 + 2 × 0.0545)
= Exp(5.4179)
= \$225.41

Bottom border of price channel:

Exp(Y1,238)
= Exp(a + b × X1,238 – 2 × s)
= Exp(a + b × 1,799 – 2 × s)
= Exp(2.8509 + 0.0014 × 1,799 – 2 × 0.0545)
= Exp(5.1999)
= \$181.25

#### Description

• The primary trend is increasing.
• The growth rate of the primary trend is 64.66% per annum.
• AMZN price at the close of August 13, 2024 was \$170.23 and was lower than the bottom border of the primary price channel by \$17.83 (9.48%). This indicates a possible reversal in the primary trend direction.

### Secondary Trend

Start date: February 2, 2024
End date: August 1, 2024

a = 4.1848

b = 0.0006

s = 0.0267

Annual growth rate:

Exp(365 × b) – 1
= Exp(365 × 0.0006) – 1
= 24.05%

Exp(4 × s) – 1
= Exp(4 × 0.0267) – 1
= 11.27%

#### February 2, 2024 calculations

Top border of price channel:

Exp(Y1,125)
= Exp(a + b × X1,125 + 2 × s)
= Exp(a + b × 1,633 + 2 × s)
= Exp(4.1848 + 0.0006 × 1,633 + 2 × 0.0267)
= Exp(5.2025)
= \$181.73

Bottom border of price channel:

Exp(Y1,125)
