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: December 15, 2022
End date: November 14, 2024

a = 2.7770

b = 0.0018

s = 0.0678

Annual growth rate:

Exp(365 × b) – 1
= Exp(365 × 0.0018) – 1
= 91.83%

Price channel spread:

Exp(4 × s) – 1
= Exp(4 × 0.0678) – 1
= 31.14%

December 15, 2022 calculations

Top border of price channel:

Exp(Y772)
= Exp(a + b × X772 + 2 × s)
= Exp(a + b × 1,120 + 2 × s)
= Exp(2.7770 + 0.0018 × 1,120 + 2 × 0.0678)
= Exp(4.9114)
= $135.83

Bottom border of price channel:

Exp(Y772)
= Exp(a + b × X772 – 2 × s)
= Exp(a + b × 1,120 – 2 × s)
= Exp(2.7770 + 0.0018 × 1,120 – 2 × 0.0678)
= Exp(4.6403)
= $103.58

= Exp(a + b × 1,820 + 2 × s)
= Exp(2.7770 + 0.0018 × 1,820 + 2 × 0.0678)
= Exp(6.1607)
= $473.77

Bottom border of price channel:

Exp(Y1,253)
= Exp(a + b × X1,253 – 2 × s)
= Exp(a + b × 1,820 – 2 × s)
