  • The decline rate of the primary trend is 11.54% per annum.
  • RDN price at the close of April 3, 2025 was $32.85 and was inside the primary price channel.
  • The secondary trend is increasing.
  • The growth rate of the secondary trend is 374.18% per annum.
  • RDN price at the close of April 3, 2025 was lower than the bottom border of the secondary price channel by $0.59 (1.76%). This indicates a possible reversal in the secondary trend direction.

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 RDN 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: July 16, 2024
End date: March 31, 2025

a = 4.0771

b = -0.0003

s = 0.0288

Annual growth rate:

Exp(365 × b) – 1
= Exp(365 × -0.0003) – 1
= -11.54%

Price channel spread:

Exp(4 × s) – 1
= Exp(4 × 0.0288) – 1
= 12.20%

July 16, 2024 calculations

Top border of price channel:

Exp(Y1,075)
= Exp(a + b × X1,075 + 2 × s)
= Exp(a + b × 1,562 + 2 × s)
= Exp(4.0771 + -0.0003 × 1,562 + 2 × 0.0288)
= Exp(3.6100)
= $36.97

Bottom border of price channel:

Exp(Y1,075)
= Exp(a + b × X1,075 – 2 × s)
= Exp(a + b × 1,562 – 2 × s)
= Exp(4.0771 + -0.0003 × 1,562 – 2 × 0.0288)
= Exp(3.4949)
= $32.95

March 31, 2025 calculations

Top border of price channel:

Exp(Y1,252)
= Exp(a + b × X1,252 + 2 × s)
= Exp(a + b × 1,820 + 2 × s)
= Exp(4.0771 + -0.0003 × 1,820 + 2 × 0.0288)
= Exp(3.5233)
= $33.90

Bottom border of price channel:

Exp(Y1,252)
= Exp(a + b × X1,252 – 2 × s)
= Exp(a + b × 1,820 – 2 × s)
= Exp(4.0771 + -0.0003 × 1,820 – 2 × 0.0288)
= Exp(3.4082)
= $30.21

Description

  • The primary trend is decreasing.
  • The decline rate of the primary trend is 11.54% per annum.

Secondary Trend

Start date: March 11, 2025
End date: April 2, 2025

a = -4.2473

b = 0.0043

s = 0.0083

Annual growth rate:

Exp(365 × b) – 1
= Exp(365 × 0.0043) – 1
= 374.18%

Price channel spread:

Exp(4 × s) – 1
= Exp(4 × 0.0083) – 1
= 3.38%

March 11, 2025 calculations

Top border of price channel:

Exp(Y1,238)
= Exp(a + b × X1,238 + 2 × s)
= Exp(a + b × 1,800 + 2 × s)
= Exp(-4.2473 + 0.0043 × 1,800 + 2 × 0.0083)
= Exp(3.4448)
= $31.34

Bottom border of price channel:

Exp(Y1,238)
= Exp(a + b × X1,238 – 2 × s)
= Exp(a + b × 1,800 – 2 × s)
= Exp(-4.2473 + 0.0043 × 1,800 – 2 × 0.0083)
= Exp(3.4116)
= $30.31

April 2, 2025 calculations

Top border of price channel:

Exp(Y1,254)
= Exp(a + b × X1,254 + 2 × s)
= Exp(a + b × 1,822 + 2 × s)
= Exp(-4.2473 + 0.0043 × 1,822 + 2 × 0.0083)
= Exp(3.5386)
= $34.42

Bottom border of price channel:

Exp(Y1,254)
= Exp(a + b × X1,254 – 2 × s)
