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 AAL 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: February 21, 2024
End date: July 25, 2024
a = 7.0125
b = -0.0025
s = 0.0606
Annual growth rate:
Exp(365 × b) – 1
= Exp(365 × -0.0025) – 1
= -60.45%
Price channel spread:
Exp(4 × s) – 1
= Exp(4 × 0.0606) – 1
= 27.42%

Top border of price channel:
Exp(Y1,150)
= Exp(a + b × X1,150 + 2 × s)
= Exp(a + b × 1,671 + 2 × s)
= Exp(7.0125 + -0.0025 × 1,671 + 2 × 0.0606)
= Exp(2.8866)
= $17.93
Bottom border of price channel:
Exp(Y1,150)
= Exp(a + b × X1,150 – 2 × s)
= Exp(a + b × 1,671 – 2 × s)
= Exp(7.0125 + -0.0025 × 1,671 – 2 × 0.0606)
= Exp(2.6443)
= $14.07

Top border of price channel:
Exp(Y1,257)
= Exp(a + b × X1,257 + 2 × s)
= Exp(a + b × 1,826 + 2 × s)
= Exp(7.0125 + -0.0025 × 1,826 + 2 × 0.0606)
= Exp(2.4927)
= $12.09
Bottom border of price channel:
Exp(Y1,257)
= Exp(a + b × X1,257 – 2 × s)
= Exp(a + b × 1,826 – 2 × s)
= Exp(7.0125 + -0.0025 × 1,826 – 2 × 0.0606)
= Exp(2.2504)
= $9.49
