* Goldman Sachs, Apple to report
* Euro hits two-month high against dollar
* Stocks fail to hang on to gains
* Wall Street set for losses
By Jeremy Gaunt, European Investment Correspondent
LONDON, July 20 (Reuters) - Worries about the U.S. economic recovery and bank exposure to risky debt swayed financial markets on Tuesday, snuffing out a short stock rally and cutting gains in the euro.
Wall Street looked set to open lower with key earnings from Goldman Sachs <GS.N> and Apple <AAPL.O> ahead.
There was growing concern about the U.S. economy after Monday's NAHB/Wells Fargo Housing Market index for July fell more than expected after a popular tax credit for homebuyers expired in April.
That underlined fears about the recovery ahead of housing data including housing starts on Tuesday.
Investor sentiment was also undermined when Hungary sold less of its debt than expected. Its talks with international lenders were suspended at the weekend.
World stocks as measured by MSCI <.MIWD00000PUS> were down a quarter of a percent with the emerging market benchmark trimming early gains to 0.3 percent. The Thomson Reuters global stock index <.TRXFLDGLPU> was down 0.2 percent.
European stocks were heading for a five-day losing streak with the pan-European FTSEurofirst 300 <
> down 0.6 percent.Earnings remained a focus, however.
"The market will look for guidance (from companies) for Q3 and to see how that is going and will be sensitive to any expressions of confidence or the lack of it," said Bernard McAlinden, investment strategist at NCB Stockbrokers in Dublin. Japan's benchmark Nikkei stock index <
> shed 1.2 percent, reflecting investor concern about a U.S. slowdown.
EURO REVERSES
The euro was lower, reversing a climb to its highest against the dollar in more than two months.
It retreated from $1.3029 hit on trading platform EBS as some investors questioned whether the single currency would sustain gains above $1.30 given that bank stress test results due on Friday may show weakness in euro zone financial institutions.
The poor demand at Hungary's bill offer also stung the euro as it weighed on risk sentiment.
"We've seen risk appetite claw back a fair amount, and the market is questioning whether that move is valid," said Jane Foley, director of research at Forex.com.
The euro <EUR=> traded 0.3 percent lower on the day at a session trough of $1.2903.
German government bonds rose as European stocks plumbed fresh two-week lows while the Hungary news further boosted flight-to-safety flows.
"It shows that sovereign risks still remain a concern in some areas and whilst the situation has generally improved, it hasn't gone away," said Nick Stamenkovic, strategist at RIA Capital Markets in Edinburgh.
