I wish to know how many Stocks Per Day on avg. show a daily change of
over 2% in either direction. This is ragarding the US stock market.
I will rephrase, How many stocks, every day on average, show more then
a two (2%) percent change?

Thank you,

Chupik --

As Vballguy points out, there is quite a difference in stock
volatility at different periods.  Here, for example is a graph of
daily returns of the S&P500 since 1928 -- and periods of market
downturns like the Great Depression have great volatility.  Analysts
are continually debating whether markets today are more volatile -- or
less volatile:

I actually don't think that it will be possible to answer your
question without custom research.

Best regards,

I can give you the number of stocks that have gone up or down by more
than 2% for each day for the next few days, if that would be of
interest to you (in other words, I can track the numbers between now
and, say, Thursday).

I do not know of a managable way to get this data for a long period
over the past years (or decades) in order to give an average figure.

Would the numbers for the next few days meet your needs?

Thank you all for fast inquiries.

A week's data(5 working days) will be good for me.
That is The Per Day Avg for a 5 days period.

Please inform me afterwards, against my payment ofcorse of your data
source and how to obtain it.

I have your data, taken from nearly 9,000 stocks over the last five
trading days. Such data is simply not available in bulk for free, or
even for a few dollars a month. Most free sites limit portfolio sizes
to a few hundred stocks. I got the information from a proprietary
database of actual closing prices. Day 1 is yesterday's close, and the
next four days represent the four days before yesterday.

Dear Vercingatorix,

Thank you very much.
However, I have to rely on an information source since without it, if
I use the information it would have the same value as my guess will.
Other then that it is an A+ answer.

Waiting for clerification,

Please rest assured the information is accurate over the period I
provided. I take my role as a researcher seriously. Market volatility
will indeed change over time, and I regret that I cannot provide you
with a way to capture this information on a regular basis in the

I answer stock-related questions all the time, using public
information (stock prices are indeed public information, accessible to
anyone with enough computer power to collect them). But I have access
to software that collects such data, and the type of information you
seek is just not available online, or at least I've never found a
source for that much data in my years of online research.

To be honest with you, if you had said in your question that you
needed a source you could use in the future, I wouldn't have answered
the question, because I don't believe such a source exists unless
you're willing to pay serious bucks. I thought you simply wanted a
picture of stock volatility over a five-day period, and that's what I
provided. Sorry if that's not what you had in mind.

If this is data you want to track in the future, I'd suggest you make
a deal with a local firm that has access to a financial database, and
offer to pay them a fee for monthly reports like the one I provided
you. It would not be cheap, but you'd have the data you need. Possible
sources for the data would be brokerages and money-management

Alternatively, you could try to purchase the data from any one of a
number of companies that provide it for financial professionals and
investors. Here are some links you can try out:

I don't know much about these different companies, though all should
be able to provide you with the data you want, with varying levels of
cost and sophistication.

chupik-ga rated this answer:4 out of 5 stars and gave an additional tip of: $5.00
I was about to give 5 stars, when I found out I stated clearly "an
answer without source wont be accepted".
However and since I cannot use the information the way I was going to.
I think it does not deserve the tip.
I will give only 5$ tip

You might want to include some additional details.

1) Which markets? (Nasdaq, AMEX, NYSE, etc) 
2) What time frame?  ie:

The average number of nasdaq stocks that had a 2% or greater change
over the past seven days is:  xxxxxx

Hello folks,

Thanks to vercingatorix-ga for answering this question, which I
thought I would be able to answer myself, but I'm afraid I got

Anyway, it might help to know that the source I was using -- which is
free and easily available -- is the Yahoo advanced stock screener at:

Click on the link that reads: "Launch Yahoo! Finance Stock Screener",
and it will download a temporary screener that can return a listing
for all stocks that closed above (or) below X% from the previous close
-- you can set X at any value you want.

Give it a try, and see if it helps out.

Thanks, chupik-ga,

You got some really good information in your answer, here.  But do
give the Yahoo screener a try if you need a public source of info.
