### 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 SEDG 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: February 14, 2023

End date: November 1, 2024

a = 12.0369

b = -0.0050

s = 0.1819

Annual growth rate:

Exp(365 × b) – 1

= Exp(365 × -0.0050) – 1

= -83.93%

Price channel spread:

Exp(4 × s) – 1

= Exp(4 × 0.1819) – 1

= 106.98%

#### February 14, 2023 calculations

Top border of price channel:

Exp(Y_{825})

= Exp(a + b × X_{825} + 2 × s)

= Exp(a + b × 1,198 + 2 × s)

= Exp(12.0369 + -0.0050 × 1,198 + 2 × 0.1819)

= Exp(6.3994)

= $601.46

Bottom border of price channel:

Exp(Y_{825})

= Exp(a + b × X_{825} – 2 × s)

= Exp(a + b × 1,198 – 2 × s)

= Exp(12.0369 + -0.0050 × 1,198 – 2 × 0.1819)

= Exp(5.6719)

= $290.59

#### November 1, 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(12.0369 + -0.0050 × 1,824 + 2 × 0.1819)

= Exp(3.2635)

= $26.14

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(12.0369 + -0.0050 × 1,824 – 2 × 0.1819)

= Exp(2.5360)

= $12.63

#### Description

- The primary trend is decreasing.
- The decline rate of the primary trend is 83.93% per annum.
- SEDG price at the close of November 1, 2024 was $17.69 and was inside the primary price channel.

### Secondary Trend

Start date: February 12, 2024

End date: November 1, 2024

a = 14.6335

b = -0.0065

s = 0.1270

Annual growth rate:

Exp(365 × b) – 1

= Exp(365 × -0.0065) – 1

= -90.75%

Price channel spread:

Exp(4 × s) – 1

= Exp(4 × 0.1270) – 1

= 66.19%

#### February 12, 2024 calculations
