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: June 27, 2024
End date: March 31, 2025

a = 8.3012

b = -0.0013

s = 0.0518

Annual growth rate:

Exp(365 × b) – 1
= Exp(365 × -0.0013) – 1
= -36.64%

Price channel spread:

Exp(4 × s) – 1
= Exp(4 × 0.0518) – 1
= 23.00%

Top border of price channel:

Exp(Y1,066)
= Exp(a + b × X1,066 + 2 × s)
= Exp(a + b × 1,548 + 2 × s)
= Exp(8.3012 + -0.0013 × 1,548 + 2 × 0.0518)
= Exp(6.4693)
= $645.04

Bottom border of price channel:

Exp(Y1,066)
= Exp(a + b × X1,066 – 2 × s)
= Exp(a + b × 1,548 – 2 × s)
= Exp(8.3012 + -0.0013 × 1,548 – 2 × 0.0518)
= Exp(6.2623)
= $524.41

Top border of price channel:

Exp(Y1,255)
= Exp(a + b × X1,255 + 2 × s)
= Exp(a + b × 1,825 + 2 × s)
= Exp(8.3012 + -0.0013 × 1,825 + 2 × 0.0518)
= Exp(6.1230)
= $456.23

Bottom border of price channel:

Exp(Y1,255)
= Exp(a + b × X1,255 – 2 × s)
= Exp(a + b × 1,825 – 2 × s)

= Exp(5.9160)
= $370.91
