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%

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

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
