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 COST 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: February 28, 2023
End date: November 20, 2024
a = 4.6141
b = 0.0012
s = 0.0439
Annual growth rate:
Exp(365 × b) – 1
= Exp(365 × 0.0012) – 1
= 56.96%
Price channel spread:
Exp(4 × s) – 1
= Exp(4 × 0.0439) – 1
= 19.18%

Top border of price channel:
Exp(Y821)
= Exp(a + b × X821 + 2 × s)
= Exp(a + b × 1,195 + 2 × s)
= Exp(4.6141 + 0.0012 × 1,195 + 2 × 0.0439)
= Exp(6.1779)
= $481.98
Bottom border of price channel:
Exp(Y821)
= Exp(a + b × X821 – 2 × s)
= Exp(a + b × 1,195 – 2 × s)
= Exp(4.6141 + 0.0012 × 1,195 – 2 × 0.0439)
= Exp(6.0024)
= $404.39
