News Summary: Investors mull candidates' tax plans

CHANGE INEVITABLE: With the outcome of next month's presidential election increasingly hazy, here's a shred of clarity that investors can cling to: The tax rates they pay on investment income like stock profits and dividends are almost certain to change.

OBAMA PLAN: President Barack Obama would boost the rate on stock profits, known as capital gains, to 20 percent for higher earners and leave it at 15 percent for everyone else. On dividends, he would tax high earners' dividends as ordinary income, up to 39.6 percent for the wealthiest Americans.

ROMNEY RECIPE: For both capital gains and dividends, Mitt Romney wants to maintain the current 15 percent rate for wealthier people and eliminate the tax entirely for everyone else.
