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 MPWR 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: June 12, 2024
End date: April 29, 2025
a = 9.3334
b = -0.0017
s = 0.1159
Annual growth rate:
Exp(365 × b) – 1
= Exp(365 × -0.0017) – 1
= -45.50%
Price channel spread:
Exp(4 × s) – 1
= Exp(4 × 0.1159) – 1
= 58.96%

Top border of price channel:
Exp(Y1,036)
= Exp(a + b × X1,036 + 2 × s)
= Exp(a + b × 1,504 + 2 × s)
= Exp(9.3334 + -0.0017 × 1,504 + 2 × 0.1159)
= Exp(7.0638)
= $1,168.84
Bottom border of price channel:
Exp(Y1,036)
= Exp(a + b × X1,036 – 2 × s)
= Exp(a + b × 1,504 – 2 × s)
= Exp(9.3334 + -0.0017 × 1,504 – 2 × 0.1159)
= Exp(6.6003)
= $735.29

= Exp(6.5299)
= $685.33
Bottom border of price channel:
Exp(Y1,255)
= Exp(a + b × X1,255 – 2 × s)
