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 POWI 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: May 18, 2023
End date: January 26, 2026
a = 5.1652
b = -0.0008
s = 0.0925
Annual growth rate:
Exp(365 × b) – 1
= Exp(365 × -0.0008) – 1
= -25.83%
Price channel spread:
Exp(4 × s) – 1
= Exp(4 × 0.0925) – 1
= 44.78%

Top border of price channel:
Exp(Y556)
= Exp(a + b × X556 + 2 × s)
= Exp(a + b × 805 + 2 × s)
= Exp(5.1652 + -0.0008 × 805 + 2 × 0.0925)
= Exp(4.6911)
= $108.97
Bottom border of price channel:
Exp(Y556)
= Exp(a + b × X556 – 2 × s)
= Exp(a + b × 805 – 2 × s)
= Exp(5.1652 + -0.0008 × 805 – 2 × 0.0925)
= Exp(4.3210)
= $75.27
