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 AMT 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: June 20, 2025
End date: December 19, 2025
a = 7.7124
b = -0.0014
s = 0.0250
Annual growth rate:
Exp(365 × b) – 1
= Exp(365 × -0.0014) – 1
= -40.11%
Price channel spread:
Exp(4 × s) – 1
= Exp(4 × 0.0250) – 1
= 10.52%

Top border of price channel:
Exp(Y1,127)
= Exp(a + b × X1,127 + 2 × s)
= Exp(a + b × 1,641 + 2 × s)
= Exp(7.7124 + -0.0014 × 1,641 + 2 × 0.0250)
= Exp(5.4573)
= $234.47
Bottom border of price channel:
Exp(Y1,127)
= Exp(a + b × X1,127 – 2 × s)
= Exp(a + b × 1,641 – 2 × s)
= Exp(7.7124 + -0.0014 × 1,641 – 2 × 0.0250)
= Exp(5.3573)
= $212.16
