  • The primary trend is increasing.
  • The growth rate of the primary trend is 244.94% per annum.
  • CTKB price at the close of September 18, 2025 was $4.09 and was inside the primary price channel.
  • The secondary trend is decreasing.
  • The decline rate of the secondary trend is 29.64% 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 CTKB 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: May 9, 2025
End date: September 18, 2025

a = -3.6901

b = 0.0034

s = 0.0748

Annual growth rate:

Exp(365 × b) – 1
= Exp(365 × 0.0034) – 1
= 244.94%

Price channel spread:

Exp(4 × s) – 1
= Exp(4 × 0.0748) – 1
= 34.87%

Top border of price channel:

Exp(Y953)
= Exp(a + b × X953 + 2 × s)
= Exp(a + b × 1,386 + 2 × s)
= Exp(-3.6901 + 0.0034 × 1,386 + 2 × 0.0748)
= Exp(1.1613)
= $3.19

Bottom border of price channel:

Exp(Y953)
= Exp(a + b × X953 – 2 × s)
= Exp(a + b × 1,386 – 2 × s)
= Exp(-3.6901 + 0.0034 × 1,386 – 2 × 0.0748)
= Exp(0.8621)
= $2.37

Top border of price channel:

Exp(Y1,043)
= Exp(a + b × X1,043 + 2 × s)
= Exp(a + b × 1,518 + 2 × s)
= Exp(-3.6901 + 0.0034 × 1,518 + 2 × 0.0748)
= Exp(1.6091)
= $5.00

Bottom border of price channel:

Exp(Y1,043)
= Exp(a + b × X1,043 – 2 × s)
= Exp(a + b × 1,518 – 2 × s)
= Exp(-3.6901 + 0.0034 × 1,518 – 2 × 0.0748)
= Exp(1.3099)
= $3.71

a = 2.8382

b = -0.0010

s = 0.0230

Annual growth rate:

Exp(365 × b) – 1
= Exp(365 × -0.0010) – 1
= -29.64%

Price channel spread:

Exp(4 × s) – 1
= Exp(4 × 0.0230) – 1
= 9.62%

Top border of price channel:

Exp(Y1,017)
= Exp(a + b × X1,017 + 2 × s)
= Exp(a + b × 1,481 + 2 × s)
= Exp(2.8382 + -0.0010 × 1,481 + 2 × 0.0230)
= Exp(1.4579)
= $4.30

Bottom border of price channel:
