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%

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

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
