November went out with a roar after six central banks joined forces to provide cheaper access to U.S. dollars in a robust response to the eurozone crisis that is threatening to capsize the world's economy.

While the immediate reaction was a 4.2% rally in the Dow Jones Industrial Average ($INDU), Wall Street was left wondering whether the pre-emptive response can contain the crisis, or if it is instead a sign that a eurozone meltdown has already begun.

The world will be watching to see what Europe will do, if anything, to address the fundamental issues behind the debt crisis. Action is still needed to support bank funding and to enforce discipline and fiscal rules, analysts say.

Investment research firm Gradient Analytics uses StockScouter to create daily and monthly stock lists. Writer Jon Markman, at the time a columnist for MSN Money, collaborated with the company to devise strategies for putting the tool to work.

One of Markman's strategies involved investing an equal amount of money in each of the stocks in the computer-generated portfolio, selling them a month later, then beginning the process again. For investors who prefer to handle fewer stocks, Markman recommended using the strategy with just the top 10 stocks on the list.

An investor who followed Markman's 10-stock strategy since it was launched in January 2001 would have realized a gain of 693% through Oct. 31 of this year, according to Gradient Analytics, and had an average annual return of 22.2%.

Over the same period, the Standard & Poor's 500 Index ($INX)was up 3.5%.
