A weak outlook from Texas Instruments weighed on the Nasdaq on Wednesday and pushed an index of chip makers below a key technical level in a worrisome sign for the market's six-month uptrend.
The PHLX semiconductor index <.SOX> fell 3 percent to close below its 50-day moving average, which represents medium-term momentum, for the first time since September.
I think the markets are ready for a sell-off that continues to be started by the Nasdaq futures markets, said Harry Michas, technical analyst and stock-index futures trader at Iharmarketmonitor.com.

Even though semis' gains have outpaced the broader market in the last several months, the S&P 500 and the semiconductor index have been moving in the same direction, which could mean further declines in the sector and spell more of the same for the overall market.
A 20-day correlation between the S&P 500 and the semiconductor index <.SOX> was at 0.77, with a reading of 1 suggesting a perfect correlation.
The semiconductor index is up 41 percent since the start of September, when the recent rally began, while the S&P 500 is up 26 percent.
High oil prices dragged on the broader market on the two-year anniversary of stocks' bull run from the S&P 500's 12-1/2-year closing low of 676.53, which was sparked by the financial crisis.
The market is at a real inflection point here, said Wayne Kaufman, chief market analyst at John Thomas Financial in New York. I'm not banging the table for the upside, but I would say there is more evidence for an upside breakout.
The Dow Jones industrial average <.DJI> dipped 1.29 points, or 0.01 percent, to finish at 12,213.09. The Standard & Poor's 500 Index <.SPX> shed 1.80 points, or 0.14 percent, to end at 1,320.02. The Nasdaq Composite Index <.IXIC> fell 14.05 points, or 0.51 percent, to close at 2,751.72.
