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 ADTN 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: July 18, 2022
End date: May 9, 2024
a = 6.2474
b = -0.0026
s = 0.1406
Annual growth rate:
Exp(365 × b) – 1
= Exp(365 × -0.0026) – 1
= -61.17%
Price channel spread:
Exp(4 × s) – 1
= Exp(4 × 0.1406) – 1
= 75.47%

Top border of price channel:
Exp(Y802)
= Exp(a + b × X802 + 2 × s)
= Exp(a + b × 1,165 + 2 × s)
= Exp(6.2474 + -0.0026 × 1,165 + 2 × 0.1406)
= Exp(3.5094)
= $33.43
Bottom border of price channel:
Exp(Y802)
= Exp(a + b × X802 – 2 × s)
= Exp(a + b × 1,165 – 2 × s)
= Exp(6.2474 + -0.0026 × 1,165 – 2 × 0.1406)
= Exp(2.9471)
= $19.05

= Exp(a + b × 1,826 + 2 × s)
= Exp(6.2474 + -0.0026 × 1,826 + 2 × 0.1406)
= Exp(1.7964)
= $6.03
Bottom border of price channel:
Exp(Y1,258)
= Exp(a + b × X1,258 – 2 × s)
= Exp(a + b × 1,826 – 2 × s)
= Exp(6.2474 + -0.0026 × 1,826 – 2 × 0.1406)
= Exp(1.2341)
= $3.44
