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 AOSL 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: April 3, 2025
End date: October 21, 2025
a = -0.9222
b = 0.0024
s = 0.0744
Annual growth rate:
Exp(365 × b) – 1
= Exp(365 × 0.0024) – 1
= 140.03%
Price channel spread:
Exp(4 × s) – 1
= Exp(4 × 0.0744) – 1
= 34.65%

Top border of price channel:
Exp(Y1,116)
= Exp(a + b × X1,116 + 2 × s)
= Exp(a + b × 1,624 + 2 × s)
= Exp(-0.9222 + 0.0024 × 1,624 + 2 × 0.0744)
= Exp(3.1223)
= $22.70
Bottom border of price channel:
Exp(Y1,116)
= Exp(a + b × X1,116 – 2 × s)
= Exp(a + b × 1,624 – 2 × s)
= Exp(-0.9222 + 0.0024 × 1,624 – 2 × 0.0744)
= Exp(2.8248)
= $16.86
