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 BJRI 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

Start date: March 4, 2022
End date: January 26, 2026

a = 3.1426

b = 0.0003

s = 0.1109

Annual growth rate:

Exp(365 × b) – 1
= Exp(365 × 0.0003) – 1
= 11.06%

Price channel spread:

Exp(4 × s) – 1
= Exp(4 × 0.1109) – 1
= 55.81%

Top border of price channel:

Exp(Y278)
= Exp(a + b × X278 + 2 × s)
= Exp(a + b × 401 + 2 × s)
= Exp(3.1426 + 0.0003 × 401 + 2 × 0.1109)
= Exp(3.4795)
= $32.44

Bottom border of price channel:

Exp(Y278)
= Exp(a + b × X278 – 2 × s)
= Exp(a + b × 401 – 2 × s)
= Exp(3.1426 + 0.0003 × 401 – 2 × 0.1109)
= Exp(3.0361)
= $20.82
