(Sharecast News) - Stocks put in a mixed performance on Monday, with the Nasdaq falling into the red but the Dow reaching a new all-time high, though gains were modest as investors adopted a cautious approach ahead of a pivotal Federal Reserve meeting on Wednesday.

The Dow Jones Industrial Average rose 0.6% to a new closing high of 41,622.08, surpassing the previous record of 41,563.08 reached on 30 August. A late rally saw the S&P 500 eke out a 0.1% gain after trading in the red for most of the session, but the Nasdaq fell 0.5%.

The subdued session follows some impressive gains made last week, with the S&P 500 and Nasdaq surging 4% and 6%, respectively, after five consecutive positive sessions.

While an easing of monetary policy has been widely expected for some time, the jury's still out on the size of potential rate cut when the Fed's two-day policy meeting concludes this week, with investors divided between a 25 basis-point (bp) and 50bp reduction in the Federal Funds Rate.

"The Fed is expected to twist but there is a degree of uncertainty here [...], as investors ponder how deep that first cut might be," said AJ Bell's head of financial analysis Danni Hewson.

"Odds of a 50bp slice have improved since last week, with an undercurrent of nervousness about the strength of the US economy still rippling through markets."

The only major economic data of the day was the NY Empire State manufacturing index, which jumped more than expected, with business activity in the area rising for the first time in nearly a year on the back of a climb in new orders and a big increase in shipments. The headline general business conditions index rose 16 points to 11.5, from -4.7 in August, beating the -3.9 reading predicted by economists.
