The information that is given is the result of a mathematical algorithm and model based on past contributions, and therefore cannot be extrapolated to the future.
The calculation is based on the cross between the trading price and the average. It generates a set of correlated matrices that seek the best ratio for Average/Weeks that can be expected on performing the operation.
Only the data from the weekly closure are used, in order to reduce the daily volatility. The data and graphs are updated on a weekly basis.
On using weekly series the data and operations are not short-term but rather medium and long-term.
The mathematical model used takes into consideration the 320 latest trading prices, which equates to about 6.15 years, and every 32 weeks approximately (which equates to about 7.5 months), the stock is re-analysed with its last 320 trading prices. This assumes that the graph and the data for the results vary, and therefore a share only needs to be updated when the last operation has been a sale and never when it is still waiting to be sold.
Only stocks that have had positive results in the long term are worked with. When a stock has a significant loss over a period, it ceases to be part of the shares portfolio.
