  • The growth rate of the primary trend is 39.54% per annum.
  • CEVA price at the close of April 29, 2025 was $26.49 and was inside the primary price channel.
  • The secondary trend is decreasing.
  • The decline rate of the secondary trend is 81.84% per annum.

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 CEVA 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 11, 2023
End date: March 27, 2025

a = 1.7752

b = 0.0009

s = 0.1217

Annual growth rate:

Exp(365 × b) – 1
= Exp(365 × 0.0009) – 1
= 39.54%

Price channel spread:

Exp(4 × s) – 1
= Exp(4 × 0.1217) – 1
= 62.74%

September 11, 2023 calculations

Top border of price channel:

Exp(Y846)
= Exp(a + b × X846 + 2 × s)
= Exp(a + b × 1,229 + 2 × s)
= Exp(1.7752 + 0.0009 × 1,229 + 2 × 0.1217)
= Exp(3.1407)
= $23.12

Bottom border of price channel:

Exp(Y846)
= Exp(a + b × X846 – 2 × s)
= Exp(a + b × 1,229 – 2 × s)
= Exp(1.7752 + 0.0009 × 1,229 – 2 × 0.1217)
= Exp(2.6537)
= $14.21

March 27, 2025 calculations

Top border of price channel:

Exp(Y1,233)
= Exp(a + b × X1,233 + 2 × s)
= Exp(a + b × 1,792 + 2 × s)
= Exp(1.7752 + 0.0009 × 1,792 + 2 × 0.1217)
= Exp(3.6546)
= $38.65

Bottom border of price channel:

Exp(Y1,233)
= Exp(a + b × X1,233 – 2 × s)
= Exp(a + b × 1,792 – 2 × s)
= Exp(1.7752 + 0.0009 × 1,792 – 2 × 0.1217)
= Exp(3.1676)
= $23.75

Secondary Trend

Start date: January 15, 2025
End date: April 23, 2025

a = 11.6638

b = -0.0047

s = 0.0874

Annual growth rate:

Exp(365 × b) – 1
= Exp(365 × -0.0047) – 1
= -81.84%

Price channel spread:

Exp(4 × s) – 1
= Exp(4 × 0.0874) – 1
= 41.87%

January 15, 2025 calculations

Top border of price channel:

Exp(Y1,184)
= Exp(a + b × X1,184 + 2 × s)
= Exp(a + b × 1,721 + 2 × s)
= Exp(11.6638 + -0.0047 × 1,721 + 2 × 0.0874)
= Exp(3.7950)
= $44.48

Bottom border of price channel:

Exp(Y1,184)
= Exp(a + b × X1,184 – 2 × s)
= Exp(a + b × 1,721 – 2 × s)
= Exp(11.6638 + -0.0047 × 1,721 – 2 × 0.0874)
= Exp(3.4453)
= $31.35

April 23, 2025 calculations

Top border of price channel:

Exp(Y1,251)
= Exp(a + b × X1,251 + 2 × s)
= Exp(a + b × 1,819 + 2 × s)
= Exp(11.6638 + -0.0047 × 1,819 + 2 × 0.0874)
= Exp(3.3370)
= $28.13

Bottom border of price channel:

Exp(Y1,251)
= Exp(a + b × X1,251 – 2 × s)
= Exp(a + b × 1,819 – 2 × s)
