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 IEX 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: March 1, 2024
End date: July 10, 2024

a = 8.5704

b = -0.0018

s = 0.0198

Annual growth rate:

Exp(365 × b) – 1
= Exp(365 × -0.0018) – 1
= -48.61%

Price channel spread:

Exp(4 × s) – 1
= Exp(4 × 0.0198) – 1
= 8.24%

Top border of price channel:

Exp(Y1,156)
= Exp(a + b × X1,156 + 2 × s)
= Exp(a + b × 1,677 + 2 × s)
= Exp(8.5704 + -0.0018 × 1,677 + 2 × 0.0198)
= Exp(5.5512)
= $257.56

Bottom border of price channel:

Exp(Y1,156)
= Exp(a + b × X1,156 – 2 × s)
= Exp(a + b × 1,677 – 2 × s)
= Exp(8.5704 + -0.0018 × 1,677 – 2 × 0.0198)
= Exp(5.4721)
= $237.95

July 10, 2024 calculations

Top border of price channel:

Exp(Y1,245)
= Exp(a + b × X1,245 + 2 × s)
= Exp(a + b × 1,808 + 2 × s)
= Exp(8.5704 + -0.0018 × 1,808 + 2 × 0.0198)
= Exp(5.3123)
= $202.82

Bottom border of price channel:

Exp(Y1,245)
= Exp(a + b × X1,245 – 2 × s)
= Exp(a + b × 1,808 – 2 × s)
= Exp(8.5704 + -0.0018 × 1,808 – 2 × 0.0198)
= Exp(5.2331)
= $187.38
