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: March 31, 2025

a = 6.3202

b = -0.0010

s = 0.0574

Annual growth rate:

Exp(365 × b) – 1
= Exp(365 × -0.0010) – 1
= -29.81%

Price channel spread:

Exp(4 × s) – 1
= Exp(4 × 0.0574) – 1
= 25.81%

February 14, 2024 calculations

Top border of price channel:

Exp(Y974)
= Exp(a + b × X974 + 2 × s)
= Exp(a + b × 1,414 + 2 × s)
= Exp(6.3202 + -0.0010 × 1,414 + 2 × 0.0574)
= Exp(5.0638)
= $158.19

Bottom border of price channel:

Exp(Y974)
= Exp(a + b × X974 – 2 × s)
= Exp(a + b × 1,414 – 2 × s)
= Exp(6.3202 + -0.0010 × 1,414 – 2 × 0.0574)
= Exp(4.8342)
= $125.74

March 31, 2025 calculations

Top border of price channel:

Exp(Y1,255)
= Exp(a + b × X1,255 + 2 × s)
= Exp(a + b × 1,825 + 2 × s)
= Exp(6.3202 + -0.0010 × 1,825 + 2 × 0.0574)
= Exp(4.6653)
= $106.19

Bottom border of price channel:

Exp(Y1,255)
= Exp(a + b × X1,255 – 2 × s)
= Exp(a + b × 1,825 – 2 × s)
= Exp(6.3202 + -0.0010 × 1,825 – 2 × 0.0574)
= Exp(4.4356)
= $84.41
