Tech stocks got off to a slightly upbeat start Tuesday morning, fueled by Intel’s $5.4 billion proposed acquisition of Tower Semiconductor. At last look, the Nasdaq Composite traded up by about 1.72%, the S&P 500 up by around 1.11% and the Dow Jones industrials up by 0.8%. The S&P 500 and the Dow closed lower on Monday while the Nasdaq ended the day flat.

Tuesday morning’s report on January’s producer price index (PPI), rather than giving traders heartburn, led them to open their wallets and push the major indexes all up by more than a full percentage point. The headline number rose by 1.0% in January, double the consensus estimate for a rise of 0.5% and more than double December’s 0.4% increase. The PPI has increased by 9.7% since January of last year.

The uptick in index values may be down more to a report that Russia has said it is withdrawing some troops from its border with Ukraine. More than 130,000 troops had been moved to the border, and the Russians did not say how many were being withdrawn.

Consumer cyclicals was the only sector trading higher (up 0.2%) in the early going. The other 10 market sectors traded lower in the first half-hour or so of trading, with energy down 2.1% and health care down 1.1%.

Here are 13 Nasdaq 100 index stocks that were making the biggest moves early Monday.

Tower Semiconductor Ltd. (NASDAQ: TSEM) traded up by about 42% to $46.92, above its 52-week range of $24.81 to $41.31, following an announced $5.4 billion acquisition of the Israel-based analog device maker. Tower’s chips are used in a variety of devices, including automobiles, and its acquisition boosts Intel’s manufacturing capacity and technology portfolio. Tower is not included in the Nasdaq 100 index, but it is easily Tuesday’s biggest mover among tech stocks.
