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 ALLY 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

End date: December 16, 2025
a = 2.8308
b = 0.0005
s = 0.1133
Annual growth rate:
Exp(365 × b) – 1
= Exp(365 × 0.0005) – 1
= 20.16%
Price channel spread:
Exp(4 × s) – 1
= Exp(4 × 0.1133) – 1
= 57.34%

Top border of price channel:
Exp(Y444)
= Exp(a + b × X444 + 2 × s)
= Exp(a + b × 645 + 2 × s)
= Exp(2.8308 + 0.0005 × 645 + 2 × 0.1133)
= Exp(3.3819)
= $29.43
Bottom border of price channel:
Exp(Y444)
= Exp(a + b × X444 – 2 × s)
= Exp(a + b × 645 – 2 × s)
= Exp(2.8308 + 0.0005 × 645 – 2 × 0.1133)
= Exp(2.9286)
= $18.70
