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 AMKR 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: March 28, 2025
a = 7.0067
b = -0.0022
s = 0.0732
Annual growth rate:
Exp(365 × b) – 1
= Exp(365 × -0.0022) – 1
= -55.11%
Price channel spread:
Exp(4 × s) – 1
= Exp(4 × 0.0732) – 1
= 34.01%

Top border of price channel:
Exp(Y1,057)
= Exp(a + b × X1,057 + 2 × s)
= Exp(a + b × 1,534 + 2 × s)
= Exp(7.0067 + -0.0022 × 1,534 + 2 × 0.0732)
= Exp(3.7869)
= $44.12
Bottom border of price channel:
Exp(Y1,057)
= Exp(a + b × X1,057 – 2 × s)
= Exp(a + b × 1,534 – 2 × s)
= Exp(7.0067 + -0.0022 × 1,534 – 2 × 0.0732)
= Exp(3.4941)
= $32.92

= Exp(a + b × 1,823 + 2 × s)
= Exp(7.0067 + -0.0022 × 1,823 + 2 × 0.0732)
= Exp(3.1527)
= $23.40
Bottom border of price channel:
Exp(Y1,255)
= Exp(a + b × X1,255 – 2 × s)
= Exp(a + b × 1,823 – 2 × s)
= Exp(7.0067 + -0.0022 × 1,823 – 2 × 0.0732)
= Exp(2.8599)
= $17.46
