### 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 ADBE 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: September 13, 2022
End date: February 14, 2024

a = 3.8688

b = 0.0016

s = 0.0732

Annual growth rate:

Exp(365 × b) – 1
= Exp(365 × 0.0016) – 1
= 81.11%

Exp(4 × s) – 1
= Exp(4 × 0.0732) – 1
= 34.00%

#### September 13, 2022 calculations

Top border of price channel:

Exp(Y753)
= Exp(a + b × X753 + 2 × s)
= Exp(a + b × 1,092 + 2 × s)
= Exp(3.8688 + 0.0016 × 1,092 + 2 × 0.0732)
= Exp(5.7920)
= \$327.67

Bottom border of price channel:

Exp(Y753)
= Exp(a + b × X753 – 2 × s)
= Exp(a + b × 1,092 – 2 × s)
= Exp(3.8688 + 0.0016 × 1,092 – 2 × 0.0732)
= Exp(5.4993)
= \$244.53

#### February 14, 2024 calculations

Top border of price channel:

Exp(Y1,110)
= Exp(a + b × X1,110 + 2 × s)
= Exp(a + b × 1,611 + 2 × s)
= Exp(3.8688 + 0.0016 × 1,611 + 2 × 0.0732)
= Exp(6.6365)
= \$762.43

Bottom border of price channel:

Exp(Y1,110)
= Exp(a + b × X1,110 – 2 × s)
= Exp(a + b × 1,611 – 2 × s)
= Exp(3.8688 + 0.0016 × 1,611 – 2 × 0.0732)
= Exp(6.3438)
= \$568.97

#### Description

• The primary trend is increasing.
• The growth rate of the primary trend is 81.11% per annum.
• ADBE price at the close of September 16, 2024 was \$521.50 and was lower than the bottom border of the primary price channel by \$285.79 (35.40%). This indicates a possible reversal in the primary trend direction.

### Secondary Trend

Start date: June 13, 2023
End date: September 16, 2024

a = 6.3001

b = 0.0000

s = 0.0856

Annual growth rate:

Exp(365 × b) – 1
= Exp(365 × 0.0000) – 1
= -0.29%

Exp(4 × s) – 1
= Exp(4 × 0.0856) – 1
= 40.82%

#### June 13, 2023 calculations

Top border of price channel:

Exp(Y941)
= Exp(a + b × X941 + 2 × s)
= Exp(a + b × 1,365 + 2 × s)
= Exp(6.3001 + 0.0000 × 1,365 + 2 × 0.0856)
= Exp(6.4603)
= \$639.23

Bottom border of price channel:
