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 SNDK 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 14, 2025
End date: March 2, 2026

a = 1.7427

b = 0.0132

s = 0.1803

Annual growth rate:

Exp(365 × b) – 1
= Exp(365 × 0.0132) – 1
= 12,120.35%

Price channel spread:

Exp(4 × s) – 1
= Exp(4 × 0.1803) – 1
= 105.70%

July 14, 2025 calculations

Top border of price channel:

Exp(Y96)
= Exp(a + b × X96 + 2 × s)
= Exp(a + b × 140 + 2 × s)
= Exp(1.7427 + 0.0132 × 140 + 2 × 0.1803)
= Exp(3.9466)
= $51.76

Bottom border of price channel:

Exp(Y96)
= Exp(a + b × X96 – 2 × s)
= Exp(a + b × 140 – 2 × s)
= Exp(1.7427 + 0.0132 × 140 – 2 × 0.1803)
= Exp(3.2253)
= $25.16

March 2, 2026 calculations

Top border of price channel:

Exp(Y255)
= Exp(a + b × X255 + 2 × s)
= Exp(a + b × 371 + 2 × s)
= Exp(1.7427 + 0.0132 × 371 + 2 × 0.1803)
= Exp(6.9880)
= $1,083.53

Bottom border of price channel:

Exp(Y255)
= Exp(a + b × X255 – 2 × s)
= Exp(a + b × 371 – 2 × s)
= Exp(1.7427 + 0.0132 × 371 – 2 × 0.1803)
= Exp(6.2667)
= $526.74

Secondary Trend

Start date: January 30, 2026
End date: March 6, 2026

a = 6.6727

b = -0.0007

s = 0.0679

Annual growth rate:

Exp(365 × b) – 1
= Exp(365 × -0.0007) – 1
= -23.43%

Price channel spread:

Exp(4 × s) – 1
= Exp(4 × 0.0679) – 1
= 31.22%

January 30, 2026 calculations

Top border of price channel:

Exp(Y235)
= Exp(a + b × X235 + 2 × s)
= Exp(a + b × 340 + 2 × s)
= Exp(6.6727 + -0.0007 × 340 + 2 × 0.0679)
= Exp(6.5599)
= $706.20

Bottom border of price channel:

Exp(Y235)
= Exp(a + b × X235 – 2 × s)
= Exp(a + b × 340 – 2 × s)
= Exp(6.6727 + -0.0007 × 340 – 2 × 0.0679)
= Exp(6.2882)
= $538.19

March 6, 2026 calculations

Top border of price channel:

Exp(Y259)
= Exp(a + b × X259 + 2 × s)
= Exp(a + b × 375 + 2 × s)
= Exp(6.6727 + -0.0007 × 375 + 2 × 0.0679)
= Exp(6.5343)
= $688.36

Bottom border of price channel:

Exp(Y259)
= Exp(a + b × X259 – 2 × s)
= Exp(a + b × 375 – 2 × s)
= Exp(6.6727 + -0.0007 × 375 – 2 × 0.0679)
