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 AZO 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: November 5, 2021
End date: November 19, 2024
a = 7.2296
b = 0.0005
s = 0.0492
Annual growth rate:
Exp(365 × b) – 1
= Exp(365 × 0.0005) – 1
= 18.26%
Price channel spread:
Exp(4 × s) – 1
= Exp(4 × 0.0492) – 1
= 21.73%

Top border of price channel:
Exp(Y494)
= Exp(a + b × X494 + 2 × s)
= Exp(a + b × 716 + 2 × s)
= Exp(7.2296 + 0.0005 × 716 + 2 × 0.0492)
= Exp(7.6569)
= $2,115.20
Bottom border of price channel:
Exp(Y494)
= Exp(a + b × X494 – 2 × s)
= Exp(a + b × 716 – 2 × s)
= Exp(7.2296 + 0.0005 × 716 – 2 × 0.0492)
= Exp(7.4603)
= $1,737.66

= Exp(a + b × 1,826 + 2 × s)
= Exp(7.2296 + 0.0005 × 1,826 + 2 × 0.0492)
= Exp(8.1670)
= $3,522.80
Bottom border of price channel:
Exp(Y1,257)
= Exp(a + b × X1,257 – 2 × s)
= Exp(a + b × 1,826 – 2 × s)
