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: January 23, 2023
End date: October 11, 2024
a = 4.3633
b = -0.0006
s = 0.0791
Annual growth rate:
Exp(365 × b) – 1
= Exp(365 × -0.0006) – 1
= -18.81%
Price channel spread:
Exp(4 × s) – 1
= Exp(4 × 0.0791) – 1
= 37.20%

Top border of price channel:
Exp(Y824)
= Exp(a + b × X824 + 2 × s)
= Exp(a + b × 1,197 + 2 × s)
= Exp(4.3633 + -0.0006 × 1,197 + 2 × 0.0791)
= Exp(3.8380)
= $46.43
Bottom border of price channel:
Exp(Y824)
= Exp(a + b × X824 – 2 × s)
= Exp(a + b × 1,197 – 2 × s)
= Exp(4.3633 + -0.0006 × 1,197 – 2 × 0.0791)
= Exp(3.5218)
= $33.84

Exp(Y1,257)
= Exp(a + b × X1,257 + 2 × s)
= Exp(a + b × 1,824 + 2 × s)
= Exp(4.3633 + -0.0006 × 1,824 + 2 × 0.0791)
= Exp(3.4801)
= $32.46
Bottom border of price channel:
Exp(Y1,257)
= Exp(a + b × X1,257 – 2 × s)
= Exp(a + b × 1,824 – 2 × s)
= Exp(4.3633 + -0.0006 × 1,824 – 2 × 0.0791)
= Exp(3.1638)
= $23.66
