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 COHU 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: May 17, 2023
End date: February 28, 2025
a = 4.6331
b = -0.0008
s = 0.0737
Annual growth rate:
Exp(365 × b) – 1
= Exp(365 × -0.0008) – 1
= -25.70%
Price channel spread:
Exp(4 × s) – 1
= Exp(4 × 0.0737) – 1
= 34.27%

Top border of price channel:
Exp(Y799)
= Exp(a + b × X799 + 2 × s)
= Exp(a + b × 1,157 + 2 × s)
= Exp(4.6331 + -0.0008 × 1,157 + 2 × 0.0737)
= Exp(3.8386)
= $46.46
Bottom border of price channel:
Exp(Y799)
= Exp(a + b × X799 – 2 × s)
= Exp(a + b × 1,157 – 2 × s)
= Exp(4.6331 + -0.0008 × 1,157 – 2 × 0.0737)
= Exp(3.5439)
= $34.60

Top border of price channel:
Exp(Y1,246)
= Exp(a + b × X1,246 + 2 × s)
= Exp(a + b × 1,810 + 2 × s)
= Exp(4.6331 + -0.0008 × 1,810 + 2 × 0.0737)
= Exp(3.3070)
= $27.30
Bottom border of price channel:
Exp(Y1,246)
= Exp(a + b × X1,246 – 2 × s)
= Exp(a + b × 1,810 – 2 × s)
= Exp(4.6331 + -0.0008 × 1,810 – 2 × 0.0737)
= Exp(3.0123)
= $20.33
