Updates to mid-afternoon

NEW YORK, Feb 19 (Reuters) - U.S. stocks wavered between slight gains and losses on Wednesday as investors parsed the minutes from the Federal Reserve's January policy meeting and digested the latest tariff announcements from U.S. President Donald Trump.

The S&P 500 inched higher, on course for a second consecutive record closing high, while the Nasdaq was essentially flat and the blue-chip Dow moved modestly lower.

"The market continues to work its way higher, so 'resiliency' is the watchword that I would give to the market right now," said Sam Stovall, chief investment strategist of CFRA Research in New York. "In the face of high valuations, reduced Q1 earnings estimates as well as the uncertainty surrounding global trade, the market is still leaning toward the positive side."

At the Fed's January policy meeting, the U.S. central bank left its key interest rate unchanged. The minutes show policymakers expressed concern about stubborn inflation and the potential effect of Trump's policy proposals, particularly tariffs, on their efforts to bring price growth down to their target.

"Fed is going to continue to be data-dependent and they're in no hurry to cut interest rates," Stovall added. "(There's) really nothing new, but at the same time, nothing unexpectedly negative."

Trump announced on Tuesday he would impose tariffs "in the neighborhood of 25%" on autos, semiconductors and pharmaceuticals, the latest in a series of measures that have raised concerns over the consequences of a global trade war.
