Downloading Data for Investment Analyzer InvAn-3/4

Investment Analyzer InvAn-3/4 uses free data sources to update stock prices and financial data for technical and fundamental analyses. In some rare cases, it can be difficult to download the data from the Internet. The reasons can be different - an interrupting or slow Internet connection, unstable availability of the source, or the absence of requested data (for example, some company can go out of business and its data may be erased from databases).

Despite the fact that InvAn-3/4 built with the optimization to process such kind of errors, in some critical situations, for example, after several attempts to read the fundamental (financial) data with no success, the following error message can appear in a pop-up window:






The solution for this problem is the following:

1. Click "Continue" to close the pop-up window and then click "Save".
   
2. Since it stops on a particular symbol (company), check if this symbol name still exists by visiting Yahoo! Finance or Google. If data are not available anymore, consider deleting the problematic symbol record.
   
3. If company data are available, you may try to download data again starting from the number where it stopped using button "From - To" at the bottom of the form (in our example above, go to two boxes besides the button "From - To" and enter in boxes numbers 379 and 525).
   
4. If company data are unavailable, try to download data again starting from the number after where it stopped using button "From - To" at the bottom of the form (in our example above, go to two boxes besides the button "From - To" and enter in boxes numbers 380 and 525). Later consider deleting the symbol record.
   
5. If two above steps were unsuccessful, check the Internet connection or try to download later.
   

Contributing Factors in Forecasting: Stocks vs. Stock Market and Sectors

Each company belongs to a particular industry, sector, national stock market, as well as, global stock market. If system conditions change, company and its stocks respond to this changes. Indeed, a general stock market exerts a significant influence on the behavior of an individual company stocks. That is why experienced investors always carefully watch the stock market, sectors, and industries conditions.

On the other hand, a company is a part of subsystems and global system. It means each company performance is a contributing factor in a whole system performance. So that we could analyze a single company and try to predict the behavior of the stock market. However, it is only partially possible. As example, the recent financial crisis caused by a system failure showed that system itself may have a significantly bigger risk-factor.

Since all structure and all levels of sub-structures depend mutually, it would be unwise to ignore either predictions of big, medium, or small parts or a whole system. Evidently it is possible to build a more accurate forecast by combining predictions for system, sub-systems, and elements of sub-system.

As example, let's consider a three-month forecast for stock market (515 stocks from different sectors):




stocks from different sectors:




and individual company stocks from a leading sector:




In conclusion, we could assume that there is a certain probability that the stock market will have a correction (downtrend around 8-12%) after May 6.
