Although there will always be differences of opinion, these are some of the CAPS community's most favored companies. So why does the professional analyst community look down on them?

Below we'll look closer at a handful of companies that CAPS members have bestowed the highest four- and five-star rating upon, meaning you think they have the best chance of outperforming the market. Yet Wall Street still can't muster up enough opinions to agree.

So who's got it right? The professional class of analysts, sitting in their paneled offices smoking stogies, or a motley crew of community investors pooling their best thoughts for others to share. We've got an idea on who we think will come out ahead, how about you?

Now as much as we love our CAPS community, don't invest in these companies just because they've garnered top honors. And don't sell just because Wall Street looks down on them either. Investing requires closer diligence on your part, so use these ratings as a launching pad for your own research.

A ray of hope
While the two analysts following CNinsure seem positively smitten by the Chinese insurance company despite its bipolar attitude to whether or not it actually needs cash for growth, insurance brokerage Arthur J. Gallagher & Co. has surprised analysts with its ability to generate profit and has gone on a shopping spree to bolster revenue.

Last quarter it surprised the market, posting profit from continuing operations of $0.44 a share and beating Wall Street expectations. It also snapped up a number of rivals, particularly in the benefits management area. Benefits Unlimited, Old Greenwich Consulting Group, GAB Robins North America, Behnke & Co., and Premier Risk Services have all been picked up by Gallagher over the past few months.

In contrast, the world's top insurance brokerage Aon (NYSE: AON) saw profit fall below estimates as brokerage margins declined. Aon's been shopping in the marketplace too, buying consultancy Hewitt Associates for $4.9 billion in July. The need to grow the top line has led second- and third-place brokers Marsh & McLennan and Willis Group to also pursue a growth-by-acquisition strategy.

More than three quarters of the CAPS members that rated the insurance broker believe it will outperform the broad market averages. You can ensure your thoughts on its prospects are also recorded on the Arthur J. Gallagher & Co. CAPS page.

Ride that pony
Europe's bailout of Ireland and its banks looks like it is having the intended effect of restoring confidence in the financial system. Both Bank of Ireland and Allied Irish Bank (NYSE: AIB) bounded higher after the Irish parliament preliminarily approved an austerity budget required as a condition of the bailout, but there are more votes to come.

And hurdles. Ireland's budget deficit is currently 32% of the country's GDP while Greece, which had everyone worrying about a default, has a deficit that's only 16% of GDP. Many CAPS members still cling to the notion that the government (both of Ireland and the EU) can't afford to allow the banking system in any of the endangered countries to fail and BRD2 thinks Bank of Ireland has already been given the means of its salvation.

The Bank of Ireland is fine, the EU has given the Bank of Ireland and [Allied Irish Banks] the tools to move on. If you think the Irish People are going to give up on their bank you may need to move on to another area of business. [Bank of Ireland] and [Allied Irish Banks] will be huge winners in the end.

Only you can decide if it is right to deposit Bank of Ireland into your portfolio, so add it to your watchlist and have all the Foolish news and analysis aggregated for you in a single place.

Construct an argument for growth
With a bigger market cap than U.S. Steel (NYSE: X) and AK Steel (NYSE: AKS) combined, Russian mining and metals producer Mechel is expecting to add to its gains next year as the price of coking coal rises. First-half revenue surged 76% year over year on higher sales volumes as coal and steel demand came back to life. Coking coal is essential for the production of steel, and Mechel says coal prices could rise another 20% to 25% in 2011.

With more than 1,600 CAPS members weighing in on the Russian giant, the community is well ahead of Wall Street here with 96% looking for it to outperform the broad market averages. You can steel yourself for additional growth and let us know your views on the Mechel CAPS page.
