MUTUAL FUNDS & ETFS

• Closed-End Fund Association (www.cefa.com): best resource I know of for screening for closed-end funds. You can search based on market price or NAV returns, premium/discount, leverage, or expense ratios. Closed-end funds are a special type of mutual fund that trades on the open market instead of via the fund sponsor, as is the case for mutual funds.
• ETF Connect (www.etfconnect.com): a good resource for locating exchange-traded funds, which are index funds you can trade like stocks. Includes screens for finding ETFs and basic information about each ETF, including top ten holdings.
• ETF Investment Outlook (www.etfinvestmentoutlook.com): uses technical indicators to ranks ETFs based on various price and volume indicators. Also provides a price chart including various moving averages and advance/decline line for each tracked ETF. A good resource if you want to follow a "what's hot?" approach to picking ETFs.
• Morningstar's Exchange-Traded Funds (www.morningstar.com): ETF commentaries, tutorials, and a list of all ETFs that you can sort by name, category, returns, etc. Shows considerable information about most ETFs including sector breakdowns and top 25 holdings, but strangely, Morningstar doesn't describe the fund's investment objective.
• Fund Alarm (www.fundalarm.com): mutual fund performance depends on the manager. All bets are off if the manager leaves. How do you know when a manager leaves, and what will be the effect on performance? Find out here.
• Morningstar (www.morningstar.com): Best source for mutual fund data. Also has good stock info.
