A major research firm is telling investors to get out of the US dollar, which is good news for Asian and European currencies and bad for anyone holding dollars.

• BCA Research says to sell dollars and buy the Japanese yen, Korean won, euro, Taiwan dollar, and Singapore dollar.
• The reason is simple: US interest rates after inflation are falling, and less foreign money is flowing into US markets.
• These five countries all sell more to the world than they buy, so money coming home should push their currencies up.
• The Chinese yuan should also rise, but Beijing is expected to step in and cap the gains.
• Brazil's real, the Indonesian rupiah, and the Philippine peso are seen lagging behind, so they are weak places to hide from the dollar.

Outlook: If pricey US tech stocks stumble, the foreign money propping up the dollar dries up and the slide accelerates.
