Q. Why are you posting this stock market data?
A. As a test platform for other stock market projects and to measure the interest in this type of stock data presentation.

Q. Where do these charts and tables come from?
A. The data to make these charts and tables comes from various sources. The carts and tables themselves are original, created solely for this site with the intent of making them useful for active traders. If you find theses charts or tables elsewhere they are copies - please report them to us using the contact form.

Q. How accurate is this data?
A. Errors in the stock and index data can occur during download. The software that manipulates the stock and index data has gone through several rounds of verifications for its accuracy and calculations. Many of the "Indexes" do not contain every stock existing for that stock market index, and sometimes a stock is dropped or added to an "Index" on a particular date due to the availability of its data. As a whole, the market indexes used by stock calculations do contain a representative and well screened selection of stocks (mostly stocks listed in the NYSE, AMEX, and NASDAQ).

Q. (Indexes) How is the stock index data useful?
A. It provides a very valid data point for any listed stock. If you are interested in a stock and it appears in these tables this is a very good indicator that it is at a relative low. These calculations can be used with myriad of other data points, available for any given stock, to determine where profit may exist in the market. It is a combination of these points (calculations, ratios, earnings, etc...) that will determine a successful stock market trader. It is primarily a tool for day traders, but may also be used to make long term investment decisions. However, it is only one data point and in no way tells the complete story of a stocks, or the markets potential.

Q. (Indexes) How are the % ranges decided?
A. The short answer is - to exclude stocks that are varying beyond a range that is useful in the context of these tables. The index calculations are based in the assumption that the changes in a stocks value are due to normal market fluctuations. The ranges are set to exclude data that is most likely caused by other factors, specific to the individual stock. As with all calculations presented on this site further investigation into a stock can determine if this is the case. Thus, for example, for an evaluation range of 2 days the value is set to exclude stocks whose value has changed above 12.1%. Evaluation of the index data has shown that almost any change above this value is too drastic to be considered as useful information in these tables. For longer evaluation ranges this value is set higher. The user should be advised that these ranges are not set to exclude stocks performing poorly for good reasons, but to include stocks that potentially provide greater opportunity.

Q. (Movers) How is the stock movers data useful?
A. Obviously this isn't so much a calculation as it is a unique and quick way to present data on stocks that are on the move (upward). The "Combined" table is sorted by the number of compiled ranges in which the stock appears. Thus, the stocks that are moving the most are at the top of the table. This table also provides 2 key values that indicate if it is possible to act upon the stocks recent increase. The High value for the last trading day - when compared to the closing value (also in the table) - can be used to determine (approximately) if the stock is still rising. And the trading volume to determine if the stock trades sufficiently so that the user may act upon this information. Furthermore the "Combined" table provides a link to the stock in the individual Range table so that the user can see exactly (by %) how much the stock has been rising on the listed days.

Q. (Periodic) Is the periodic data fit always correct?
A. No, some sets of data do not behave well with the mathematical fit in stock calculations (most do, however they change on a daily basis). The user should be aware that the data fit is done automatically and cannot always be checked for accuracy. When a bad fit occurs the predicted next value may be useless. Viewing the chart with the data and fit should always be done to confirm if the fit behaved appropriately.

Q. How do you use this stock and index data?
A. However you choose. There is more information here than first meets the eye. It can be used to see what stock market indexes are up or what stocks are down and which stocks are rapidly increasing in value. It provides this information over different time intervals allowing the user to determine which is relevant. Finally, it combines these different data points into concise reports. The user can decide if they want to use the whole report or only various pieces. This market data can be used to identify a low or high point for a stock that currently interests an investor. If the stock appears in these tables it is a good indicator that, excluding other influences, it may be at an action (buy/sell) level.

Q. Why are some stocks and numbers shown in bold?
A. Stock Calculations does not make picks. However, Stock Calculations does apply filters, based on various numbers, to each stock. Many stocks are filtered because they do not meet the critera of the given calculation. Others are filtered because they have bad data. Stocks and numbers in bold are ment to emphasize certain stocks or data that have "good" values. The filters include relative changes, P/E, volume, estimates, dividends and others determined by thier relivance to the given calculation.

Q. Does the stock data get posted every day?
A. The server has been performing these calculations for over two years and has a successful daily run over 99% of the time. Posting of each trading day's data usually occurs before midnight central standard time (US).

Q. Is this all there is for the stock and index data and calculations?
A. Not by a long shot. Stock Calculations does many more stock and index calculations and comparisons each night and may post the market data here as it becomes feasible.
