NEW YORK, June 28 (Reuters) - U.S. stocks rose for a second day on Tuesday as optimism grew that a solution to the Greek debt problem was near, boosting investor appetite for risky assets as equities recouped some of their recent losses.
Buyers snapped up shares after the S&P 500's 7 percent swoon since April, mostly in commodities and technology shares, as investors sought to raise their exposure going into the end of the quarter and before earnings season next month.
"The greater risk to the market is that the news is not negative and we rally on good earnings," said Marc Pado, U.S. market strategist at Cantor Fitzgerald & Co in San Francisco.
"The more the market pushes higher, the more it makes the people who are under-exposed nervous," he said.
There was a strong move into riskier cyclical areas of the market such as energy, retail and materials. Those sectors, which are more sensitive to shifts in the economy, have underperformed the market so far this year.

Greek lawmakers will vote Wednesday and Thursday on the measures, which must be passed to receive the next payment of 12 billion euros. If Greece doesn't get the funds, investors fear a Europe-wide crisis and potential credit market freeze could follow. For details, see [ID:nLDE75R0FD] [ID:nL6E7HS1AT]

While the market was generally optimistic about the vote, the CBOE Volatility Index <.VIX>, Wall Street's "fear gauge," suggested some caution. The index stood at 19.46, a number considered relatively high. (Reporting by Edward Krudy; Editing by Kenneth Barry)
