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: April 2, 2025
a = 5.2022
b = -0.0007
s = 0.0832
Annual growth rate:
Exp(365 × b) – 1
= Exp(365 × -0.0007) – 1
= -21.48%
Price channel spread:
Exp(4 × s) – 1
= Exp(4 × 0.0832) – 1
= 39.48%

Top border of price channel:
Exp(Y681)
= Exp(a + b × X681 + 2 × s)
= Exp(a + b × 987 + 2 × s)
= Exp(5.2022 + -0.0007 × 987 + 2 × 0.0832)
= Exp(4.7149)
= $111.59
Bottom border of price channel:
Exp(Y681)
= Exp(a + b × X681 – 2 × s)
= Exp(a + b × 987 – 2 × s)
= Exp(5.2022 + -0.0007 × 987 – 2 × 0.0832)
= Exp(4.3821)
= $80.01

Top border of price channel:
Exp(Y1,237)
= Exp(a + b × X1,237 + 2 × s)
= Exp(a + b × 1,798 + 2 × s)
= Exp(5.2022 + -0.0007 × 1,798 + 2 × 0.0832)
= Exp(4.1777)
= $65.22
Bottom border of price channel:
Exp(Y1,237)
= Exp(a + b × X1,237 – 2 × s)
= Exp(a + b × 1,798 – 2 × s)
= Exp(5.2022 + -0.0007 × 1,798 – 2 × 0.0832)
= Exp(3.8449)
= $46.75
