how to test stock market bubble?

Look up papers by Didier Sornette (University of California at Los Angeles), who worked on this. He finds that bubbles grow by way of an oscillating function of which amplitude and frequency permit to predict the crash.\n\nOf course the function used was found by looking at past data, but he does give predictions as well.\n\nHowever, the last time I looked at this he predicted the current run-up to end in 2004 with a crash, which didn't materialise.

h. a variety of ways.\n1.  If a stock becomes overvalued, I replace it.\n2.  If, upon periodic evaluation, I can show that a better opportunity in terms of likely long term return exists with less risk.\n3.  If the portfolio undergoes a singularity, I check to determine if the portfolio is still holding the best priced low risk stocks.  The measure of which tends to exceed my patience with writing a post.  That would actually be a technical measure since it has to do with price curves rather than fundamentals.  They occur very infrequently but tend to last quite a while.\n4. I use Kaizen as a method of process improvement, so I also update the portfolio if I can show a process in use is inferior to other processes and then remove securities purchased under the inferior process.\n\nI happen to participate in a stock picking game and it mimicks my real portfolio.  You can decide if one should use fundamentals or not.  It is at http://www.marketocracy.com/cgi-bin/WebObjects/Portfolio.woa/ps/FundPublicPage/source=CaHiHdImDlIfEbAoMaKiAbOa

Hope and pray. Pay attention to what the market and what the stock is doing, but anything you do, it is still a gamble and you risk losing.

type in MSFT into a "find a quote" box on Yahoo! Finance or MSN Money and that will tell you the most recent trade price. You'll have to open an account with a brokerage firm or an online account like sharebuilder or some similar company to buy shares.

For stocks, you can look up the beta of a company.  For example, with Yahoo Finance, it's on the key stats page\n\nhttp://finance.yahoo.com/q/ks?s=YHOO\n\nYahoo has a beta of 1.26.

This is serious - research all of the small publicly traded companies in your area.  Find the one whose stock price is most likely to explode.  Buy several thousand shares, then start talking about how great the company is.  Word of mouth can go a long way toward pushing up that share price.

The simplest way to do it is to go to finance.yahoo.com, enter the ticker for the stock you want, click key statistics, and it will be listed on the right hand side, directly under the advertisement (first item listed under stock price history).\n\nThe more complicated way is to list the average monthly price for the stock with the most recent month on top in an excel spread sheet. List the average monthly price for the SP 500 in the same fashion. Calculate the average return for the previous month for both the stock and the SP 500 by dividing one month by the previous and subtracting one from the result and expressing the answer in percentage form. After you have done that for both the stock you are interested in and the market, tell excel to calculate the covariance between the two sets of data (=cov(individual stock dataset, SP 500 dataset). Then calculate the variance for just the SP 500, (=var(sp 500 dataset). Then divide the covariance by the variance.\n\nBeta tells you how much an individual stocks price (i.e. its return) fluctuates in comparison to a market index, such as the SP 500. A beta higher than "1" and the stock is more risky than the market (i.e. it is more likely to fluctuate out of tandem with the market). Hope this helps
