Bank Dividends Are Coming: Here's What You Need to Know
Big banks JPMorgan Chase, Bank of America (NYSE: BAC), Citigroup (NYSE: C), and Wells Fargo (NYSE: WFC) have all said they plan to start paying dividends to shareholders. Is it time to buy shares and rejoice?

Fool contributor Morgan Housel took the 30% payout ratio the banks are bandying about, mixed in estimated earnings per share, and came out with yields for the four banks ranging from 2.68% to 3.14%. "Not as much as banks typically yielded before the financial crisis, but still above the average S&P 500 company's yield," Morgan wrote.

Even though the banks appear financially strong enough to handle this shareholder payment, Morgan remains leery about owning their common stock. "There's still just too much insanity and funny business left over from the bubble years," he wrote.

4 ETF Trends You Must Know About
Many investors use exchange-traded funds to easily bring a wide range of stocks into their portfolios. A recent report from Schwab outlined four trends in ETFs that Fool editor and writer Dan Caplinger thought Fools needed to know about.

In brief, ETF investors preferred funds with low expense ratios and remained partial to ETFs investing in commodities and emerging-market economies. They had an on-again/off-again relationship with bond ETFs and had a focus on dividend income.

Here's something else interesting about how ETF investors think: "[S]pecialty ETFs including SPDR Gold Trust (NYSE: GLD) and Vanguard MSCI Emerging Markets, which offer targeted exposure to narrower segments of the market, bring investors in the door -- and then they diversify beyond those niche offerings after they get comfortable with the ETF concept," Dan wrote.
