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 DIOD 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: January 12, 2023
End date: March 27, 2025
a = 5.2049
b = -0.0006
s = 0.0808
Annual growth rate:
Exp(365 × b) – 1
= Exp(365 × -0.0006) – 1
= -21.09%
Price channel spread:
Exp(4 × s) – 1
= Exp(4 × 0.0808) – 1
= 38.13%

Top border of price channel:
Exp(Y702)
= Exp(a + b × X702 + 2 × s)
= Exp(a + b × 1,017 + 2 × s)
= Exp(5.2049 + -0.0006 × 1,017 + 2 × 0.0808)
= Exp(4.7064)
= $110.65
Bottom border of price channel:
Exp(Y702)
= Exp(a + b × X702 – 2 × s)
= Exp(a + b × 1,017 – 2 × s)
= Exp(5.2049 + -0.0006 × 1,017 – 2 × 0.0808)
= Exp(4.3834)
= $80.11

Top border of price channel:
Exp(Y1,254)
= Exp(a + b × X1,254 + 2 × s)
= Exp(a + b × 1,822 + 2 × s)
= Exp(5.2049 + -0.0006 × 1,822 + 2 × 0.0808)
= Exp(4.1839)
= $65.62
Bottom border of price channel:
Exp(Y1,254)
= Exp(a + b × X1,254 – 2 × s)
= Exp(a + b × 1,822 – 2 × s)
= Exp(5.2049 + -0.0006 × 1,822 – 2 × 0.0808)
= Exp(3.8609)
= $47.51
