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: March 28, 2025
End date: October 24, 2025
a = 1.5508
b = 0.0029
s = 0.0592
Annual growth rate:
Exp(365 × b) – 1
= Exp(365 × 0.0029) – 1
= 192.34%
Price channel spread:
Exp(4 × s) – 1
= Exp(4 × 0.0592) – 1
= 26.70%

Top border of price channel:
Exp(Y1,110)
= Exp(a + b × X1,110 + 2 × s)
= Exp(a + b × 1,614 + 2 × s)
= Exp(1.5508 + 0.0029 × 1,614 + 2 × 0.0592)
= Exp(6.4127)
= $609.54
Bottom border of price channel:
Exp(Y1,110)
= Exp(a + b × X1,110 – 2 × s)
= Exp(a + b × 1,614 – 2 × s)
= Exp(1.5508 + 0.0029 × 1,614 – 2 × 0.0592)
= Exp(6.1760)
= $481.08

= Exp(7.0299)
= $1,129.92
Bottom border of price channel:
Exp(Y1,255)
= Exp(a + b × X1,255 – 2 × s)
