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 ALK 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: September 7, 2023
End date: November 1, 2023

a = 9.0084

b = -0.0051

s = 0.0151

Annual growth rate:

Exp(365 × b) – 1
= Exp(365 × -0.0051) – 1
= -84.18%

Price channel spread:

Exp(4 × s) – 1
= Exp(4 × 0.0151) – 1
= 6.23%

Top border of price channel:

Exp(Y721)
= Exp(a + b × X721 + 2 × s)
= Exp(a + b × 1,049 + 2 × s)
= Exp(9.0084 + -0.0051 × 1,049 + 2 × 0.0151)
= Exp(3.7393)
= $42.07

Bottom border of price channel:

Exp(Y721)
= Exp(a + b × X721 – 2 × s)
= Exp(a + b × 1,049 – 2 × s)
= Exp(9.0084 + -0.0051 × 1,049 – 2 × 0.0151)
= Exp(3.6789)
= $39.60

= Exp(3.4614)
= $31.86

Bottom border of price channel:

Exp(Y760)
= Exp(a + b × X760 – 2 × s)
= Exp(a + b × 1,104 – 2 × s)
= Exp(9.0084 + -0.0051 × 1,104 – 2 × 0.0151)
= Exp(3.4011)
