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 SAIA 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: July 18, 2023
End date: January 27, 2025
a = 5.6881
b = 0.0003
s = 0.1275
Annual growth rate:
Exp(365 × b) – 1
= Exp(365 × 0.0003) – 1
= 10.56%
Price channel spread:
Exp(4 × s) – 1
= Exp(4 × 0.1275) – 1
= 66.52%

Top border of price channel:
Exp(Y873)
= Exp(a + b × X873 + 2 × s)
= Exp(a + b × 1,267 + 2 × s)
= Exp(5.6881 + 0.0003 × 1,267 + 2 × 0.1275)
= Exp(6.2916)
= $539.99
Bottom border of price channel:
Exp(Y873)
= Exp(a + b × X873 – 2 × s)
= Exp(a + b × 1,267 – 2 × s)
= Exp(5.6881 + 0.0003 × 1,267 – 2 × 0.1275)
= Exp(5.7816)
= $324.28

= Exp(a + b × X1,256 + 2 × s)
= Exp(a + b × 1,826 + 2 × s)
= Exp(5.6881 + 0.0003 × 1,826 + 2 × 0.1275)
= Exp(6.4453)
= $629.74
Bottom border of price channel:
Exp(Y1,256)
= Exp(a + b × X1,256 – 2 × s)
= Exp(a + b × 1,826 – 2 × s)
= Exp(5.6881 + 0.0003 × 1,826 – 2 × 0.1275)
= Exp(5.9354)
= $378.18
