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

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%

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

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
