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 YUM 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: April 6, 2021
End date: February 5, 2025
a = 4.6560
b = 0.0001
s = 0.0532
Annual growth rate:
Exp(365 × b) – 1
= Exp(365 × 0.0001) – 1
= 5.36%
Price channel spread:
Exp(4 × s) – 1
= Exp(4 × 0.0532) – 1
= 23.70%

Top border of price channel:
Exp(Y235)
= Exp(a + b × X235 + 2 × s)
= Exp(a + b × 342 + 2 × s)
= Exp(4.6560 + 0.0001 × 342 + 2 × 0.0532)
= Exp(4.8113)
= $122.89
Bottom border of price channel:
Exp(Y235)
= Exp(a + b × X235 – 2 × s)
= Exp(a + b × 342 – 2 × s)
= Exp(4.6560 + 0.0001 × 342 – 2 × 0.0532)
= Exp(4.5986)
= $99.35

= Exp(5.0119)
= $150.18
Bottom border of price channel:
Exp(Y1,199)
= Exp(a + b × X1,199 – 2 × s)
= Exp(a + b × 1,743 – 2 × s)
