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 ANET 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: September 12, 2025
a = -3.1667
b = 0.0045
s = 0.0607
Annual growth rate:
Exp(365 × b) – 1
= Exp(365 × 0.0045) – 1
= 411.44%
Price channel spread:
Exp(4 × s) – 1
= Exp(4 × 0.0607) – 1
= 27.46%

Top border of price channel:
Exp(Y1,143)
= Exp(a + b × X1,143 + 2 × s)
= Exp(a + b × 1,661 + 2 × s)
= Exp(-3.1667 + 0.0045 × 1,661 + 2 × 0.0607)
= Exp(4.3816)
= $79.97
Bottom border of price channel:
Exp(Y1,143)
= Exp(a + b × X1,143 – 2 × s)
= Exp(a + b × 1,661 – 2 × s)
= Exp(-3.1667 + 0.0045 × 1,661 – 2 × 0.0607)
= Exp(4.1390)
= $62.74
