- The growth rate of the primary trend is 55.38% per annum.
- COST price at the close of April 26, 2024 was $729.18 and was inside the primary price channel.
- The secondary trend is decreasing.
- The decline rate of the secondary trend is 24.76% per annum.

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

Start date: March 1, 2023
End date: April 26, 2024
a = 4.4030
b = 0.0012
s = 0.0450
Annual growth rate:
Exp(365 × b) – 1
= Exp(365 × 0.0012) – 1
= 55.38%
Price channel spread:
Exp(4 × s) – 1
= Exp(4 × 0.0450) – 1
= 19.70%

Exp(Y967)
= Exp(a + b × X967 + 2 × s)
= Exp(a + b × 1,402 + 2 × s)
= Exp(4.4030 + 0.0012 × 1,402 + 2 × 0.0450)
= Exp(6.1858)
= $485.80
Bottom border of price channel:
Exp(Y967)
= Exp(a + b × X967 – 2 × s)
= Exp(a + b × 1,402 – 2 × s)
= Exp(4.4030 + 0.0012 × 1,402 – 2 × 0.0450)
= Exp(6.0060)
= $405.84
