Stocks and exchange traded funds (ETFs) started off strong this morning, but then quickly reversed course as the dollar rallied and sent oil prices moving lower.

Oil had been above $80 a barrel for much of the morning, but dropped back below that mark as the dollar continued to gain against the euro, report Donna Kardos Yesalavish and Geoffrey Rogow for The Wall Street Journal. PowerShares DB U.S. Dollar Bullish (NYSEArca: UUP) is up about 0.5% this morning. (Read our currency report for more on currencies and ETFs).

The market’s dip is also being attributed to analyst downgrades of banks and concerns that Bank of America (NYSE: BAC) will have to sell shares in order to payback bailout money it received from the government, reports Rita Nazareth for Bloomberg. The Financial Select Sector SPDR (NYSEArca: XLF) is down more than 2% this morning.

Verizon Communication (NYSE: VZ) reported this morning that its third-quarter profit fell less than expected, by 9%. Gains in the company’s wireless division helped offset slower-than-expected growth in its FiOS television service, says Sinead Carew for Reuters. Vanguard Telecom Services (NYSEArca: VOX) is down more than 2.5% this morning; Verizon is 20.3%.
