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 BA 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 20, 2023
End date: November 19, 2024
a = 7.3026
b = -0.0013
s = 0.0639
Annual growth rate:
Exp(365 × b) – 1
= Exp(365 × -0.0013) – 1
= -37.04%
Price channel spread:
Exp(4 × s) – 1
= Exp(4 × 0.0639) – 1
= 29.11%

Top border of price channel:
Exp(Y1,006)
= Exp(a + b × X1,006 + 2 × s)
= Exp(a + b × 1,461 + 2 × s)
= Exp(7.3026 + -0.0013 × 1,461 + 2 × 0.0639)
= Exp(5.5782)
= $264.59
Bottom border of price channel:
Exp(Y1,006)
= Exp(a + b × X1,006 – 2 × s)
= Exp(a + b × 1,461 – 2 × s)
= Exp(7.3026 + -0.0013 × 1,461 – 2 × 0.0639)
= Exp(5.3227)
= $204.94

Top border of price channel:
Exp(Y1,257)
= Exp(a + b × X1,257 + 2 × s)
= Exp(a + b × 1,826 + 2 × s)
= Exp(7.3026 + -0.0013 × 1,826 + 2 × 0.0639)
= Exp(5.1155)
= $166.58
Bottom border of price channel:
Exp(Y1,257)
= Exp(a + b × X1,257 – 2 × s)
= Exp(a + b × 1,826 – 2 × s)
= Exp(7.3026 + -0.0013 × 1,826 – 2 × 0.0639)
= Exp(4.8600)
= $129.02
