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 UAA 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 10, 2024
End date: November 20, 2024
a = -0.9044
b = 0.0017
s = 0.0666
Annual growth rate:
Exp(365 × b) – 1
= Exp(365 × 0.0017) – 1
= 86.30%
Price channel spread:
Exp(4 × s) – 1
= Exp(4 × 0.0666) – 1
= 30.54%

Top border of price channel:
Exp(Y1,101)
= Exp(a + b × X1,101 + 2 × s)
= Exp(a + b × 1,602 + 2 × s)
= Exp(-0.9044 + 0.0017 × 1,602 + 2 × 0.0666)
= Exp(1.9597)
= $7.10
Bottom border of price channel:
Exp(Y1,101)
= Exp(a + b × X1,101 – 2 × s)
= Exp(a + b × 1,602 – 2 × s)
= Exp(-0.9044 + 0.0017 × 1,602 – 2 × 0.0666)
= Exp(1.6931)
= $5.44

= Exp(2.3415)
= $10.40
Bottom border of price channel:
Exp(Y1,257)
= Exp(a + b × X1,257 – 2 × s)
= Exp(a + b × 1,826 – 2 × s)
