LONDON (Reuters) - World stocks attempted to steady on Wednesday following a bruising Wall Street session that wiped $1 trillion off the value of leading U.S. tech shares, while oil prices staged a modest rebound after slumping to one-year lows.
U.S. shares were set to open sharply firmer, futures indicated, after two days of losses that wiped out the S&P500's gains for the year and left the tech-heavy Nasdaq index teetering on the brink of falling into the red.
Losses have been concentrated in the technology sector, as investors lightened holdings of FAANG shares -- Facebook (NASDAQ:FB), Apple (NASDAQ:AAPL), Amazon (NASDAQ:AMZN), Netflix (NASDAQ:NFLX) and Google (NASDAQ:GOOGL) -- the group that had propelled the Wall Street's decade-long bull market.
The falls saw the Nasdaq index touch seven-month lows and energy shares too had dropped in line with a 6 percent oil price slump S&P 500 .
That fed through to Asia on Wednesday, taking MSCI's index of ex-Japan Asia-Pacific shares almost half a percent lower, but it clawed back some of those falls to trade flat by 0900 GMT. MSCI's all-country benchmark was flat too, attempting to snap two days of falls.
That, alongside a 1.5 percent bounce in Brent crude futures and some optimism over Italy's budget stance, helped European equities open 0.4 percent higher, with a tech index up half a percent.
David Vickers, senior portfolio manager at Russell Investments, noted however that gloom has tended to deepen as the Wall Street session progresses and more company earnings emerge.
"High-flying momentum stocks have come off in a fairly spectacular fashion. At one point Apple and Amazon accounted for 40 percent of U.S. equity gains and people were just recycling money into the winners," Vickers said.
"That's come off the boil and set the cat among the pigeons... We've seen a lot of reflexivity, when selling begets selling, the market starts to turn over, people take profits, it leads to another leg down and so on."
Markets also appear to be preparing for a loss of momentum in global economic growth as China takes a hit from Washington's trade tariffs and the United States comes off the sugar-high of President Donald Trump's tax cuts.

Vickers said that after 20 percent-plus earnings growth at U.S. companies, some investors were disappointed with signs this would slow to single digits as the stimulus effect wore off.
"If you have a market like the S&P500, which is two standard deviations expensive, it becomes difficult if you don't think you will get the same kinds of earnings growth in future," he added.
The growth concerns have also been revived by comments from U.S. Federal Reserve officials who suggested economic outlook concerns could slow the pace of its monetary policy tightening cycle or even end it.
The comments have knocked U.S. 10-year bond yields to near two-month lows around 3.03 percent, after trading above 3.25 percent at the start of November.
But the recovery in global sentiment allowed yields to rise around three bps to 3.08 percent while the dollar's index, which had jumped 0.7 percent on Tuesday, slipped 0.2 percent.
The euro rose after a 0.75 percent drop on Tuesday, buoyed by reports that Italy may be open to reviewing its draft budget for 2019, possibly easing a confrontation with the European Union. The League party, part of the ruling coalition, later denied the report.
Italians bond yields fell up to 16 basis points initially, putting 10-year yields on track for their biggest daily drop in almost a month but the market gave up some of its gains after the denials.

Italian bank shares too eased off session highs but were still up 2 percent on the day after sinking to two-year lows on Tuesday.
Focus is now on the European Commission which should take the first step on Wednesday towards disciplining Italy over its draft fiscal plan.
"This procedure will take several months, but stands to keep (government bonds) and the Italian banking sector under pressure. Favor euro underperformance in Europe and probably further choppy euro-dollar trading in a $1.1350-$1.1450 range," ING Bank analysts told clients.
Oil's bounce helped commodity currencies such as the Australian dollar and Norwegian crown, which recovered around 0.4 percent versus the dollar after heavy recent slides.
