Price Momentum surges, especially if accompanied by volume surges often presage a significant move.  The top 50 stocks from our momentum scan are listed along with their "volume momentum."  The list is refreshed daily.  There is an introductory video on setups and alerts on the home page (the third video below the green lettering).

 
The 12-day and 25-day momentum is tracked here.  We display the price, 25-day momentum, 12-day momentum, and 10-day average volume momentum (in that order and ranked by their 25-day momentum).  Momentum is similar to price-rate-of-change.  The difference is that momentum is expressed as a ratio, and price-rate-of-change is expressed as a percent.  Both are "momentum" measurements.  We include here an "average volume momentum" measurement.  It shows today's measurement of the average volume for the last 10 days in comparison with the same measurement as of 10 days ago.         

It is often possible to catch a stock early in a sustained move by monitoring stocks that have undergone a recent momentum surge.  Our momentum scanner computes the 12-day and 25-day momentum of each of thousands of stocks.  The 50 stocks with the greatest 25-day momentum are listed here (the list is updated daily).  Momentum is expressed in percentage terms rather than as a ratio.  Remember that a high 25-day momentum figure does not necessarily mean a viable trend has begun.  There may be nearby overhead resistance to any more upside movement.  If there is, you should either wait and see if the stock breaks through that resistance or look elsewhere.  Look at the stock's 3-year chart and it's 1-year chart to get a sense of the context for the recent momentum.  Is the stock accelerating after touching its rising trendline, breaking through its upper Bollinger band, bursting through the neckline of an inverted head-and-shoulders formation, or breaking through the upper resistance boundary of an ascending triangle?  Look for such things to validate that the momentum is probably the beginning of a significant move. 

Extreme readings are likely to presage a continuation of the upside movement.  We include two measurements here.  One is "price momentum" and the other is "average volume momentum."  if the increase in price momentum is significant, you can expect average volume to increase with the price momentum.  Check a stock carefully before you buy it.  A momentum surge may result because of a possible takeover.  In such cases, a stock will usually gap up to a certain level then level off with little price change from then on (it goes relatively flat).  There might be another surge later or the stock may stay there for up to a few months and then plummet if the takeover collapses.  In short, the upside move may already be over.  We believe it is better to look for stocks that have not spiked up abruptly, and that you make sure there is no nearby resistance overhanging the stock.  We also think it is best to avoid any high-momentum stock that has negative volume momentum.
