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 PLAB 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

Start date: September 1, 2022
End date: May 17, 2024
a = 1.3570
b = 0.0011
s = 0.1335
Annual growth rate:
Exp(365 × b) – 1
= Exp(365 × 0.0011) – 1
= 50.26%
Price channel spread:
Exp(4 × s) – 1
= Exp(4 × 0.1335) – 1
= 70.61%

Top border of price channel:
Exp(Y829)
= Exp(a + b × X829 + 2 × s)
= Exp(a + b × 1,200 + 2 × s)
= Exp(1.3570 + 0.0011 × 1,200 + 2 × 0.1335)
= Exp(2.9628)
= $19.35
Bottom border of price channel:
Exp(Y829)
= Exp(a + b × X829 – 2 × s)
= Exp(a + b × 1,200 – 2 × s)
= Exp(1.3570 + 0.0011 × 1,200 – 2 × 0.1335)
= Exp(2.4286)
= $11.34

= Exp(3.6589)
= $38.82
Bottom border of price channel:
Exp(Y1,258)
= Exp(a + b × X1,258 – 2 × s)
= Exp(a + b × 1,824 – 2 × s)
