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 AMG 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

Start date: April 9, 2025
End date: December 12, 2025
a = 1.6647
b = 0.0022
s = 0.0301
Annual growth rate:
Exp(365 × b) – 1
= Exp(365 × 0.0022) – 1
= 121.02%
Price channel spread:
Exp(4 × s) – 1
= Exp(4 × 0.0301) – 1
= 12.80%

Top border of price channel:
Exp(Y1,083)
= Exp(a + b × X1,083 + 2 × s)
= Exp(a + b × 1,576 + 2 × s)
= Exp(1.6647 + 0.0022 × 1,576 + 2 × 0.0301)
= Exp(5.1493)
= $172.31
Bottom border of price channel:
Exp(Y1,083)
= Exp(a + b × X1,083 – 2 × s)
= Exp(a + b × 1,576 – 2 × s)
