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 ENTG 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: February 14, 2024
End date: July 7, 2025

a = 6.6224

b = -0.0013

s = 0.0819

Annual growth rate:

Exp(365 × b) – 1
= Exp(365 × -0.0013) – 1
= -36.91%

Price channel spread:

Exp(4 × s) – 1
= Exp(4 × 0.0819) – 1
= 38.79%

February 14, 2024 calculations

Top border of price channel:

Exp(Y891)
= Exp(a + b × X891 + 2 × s)
= Exp(a + b × 1,294 + 2 × s)
= Exp(6.6224 + -0.0013 × 1,294 + 2 × 0.0819)
= Exp(5.1536)
= $173.05

Bottom border of price channel:

Exp(Y891)
= Exp(a + b × X891 – 2 × s)
= Exp(a + b × 1,294 – 2 × s)
= Exp(6.6224 + -0.0013 × 1,294 – 2 × 0.0819)
= Exp(4.8258)
= $124.69

July 7, 2025 calculations

Top border of price channel:

Exp(Y1,238)
= Exp(a + b × X1,238 + 2 × s)
= Exp(a + b × 1,803 + 2 × s)
= Exp(6.6224 + -0.0013 × 1,803 + 2 × 0.0819)
= Exp(4.5113)
= $91.04

Bottom border of price channel:

Exp(Y1,238)
= Exp(a + b × X1,238 – 2 × s)
= Exp(a + b × 1,803 – 2 × s)
= Exp(6.6224 + -0.0013 × 1,803 – 2 × 0.0819)
= Exp(4.1836)
= $65.60
