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 ACM 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

a = 3.9906
b = 0.0003
s = 0.0584
Annual growth rate:
Exp(365 × b) – 1
= Exp(365 × 0.0003) – 1
= 13.61%
Price channel spread:
Exp(4 × s) – 1
= Exp(4 × 0.0584) – 1
= 26.32%

Top border of price channel:
Exp(Y234)
= Exp(a + b × X234 + 2 × s)
= Exp(a + b × 341 + 2 × s)
= Exp(3.9906 + 0.0003 × 341 + 2 × 0.0584)
= Exp(4.2267)
= $68.49
Bottom border of price channel:
Exp(Y234)
= Exp(a + b × X234 – 2 × s)
= Exp(a + b × 341 – 2 × s)
= Exp(3.9906 + 0.0003 × 341 – 2 × 0.0584)
= Exp(3.9930)
= $54.22

Top border of price channel:
Exp(Y1,128)
= Exp(a + b × X1,128 + 2 × s)
= Exp(a + b × 1,638 + 2 × s)
= Exp(3.9906 + 0.0003 × 1,638 + 2 × 0.0584)
= Exp(4.6801)
= $107.78
Bottom border of price channel:
Exp(Y1,128)
= Exp(a + b × X1,128 – 2 × s)
= Exp(a + b × 1,638 – 2 × s)
= Exp(3.9906 + 0.0003 × 1,638 – 2 × 0.0584)
= Exp(4.4464)
