BERMAN: Investors are coming back from the long holiday. Will the bull market keep charging higher? Christine Romans joins us now with "CNN Money Now." Romans.</s>CHRISTINE ROMANS, CNN CHIEF BUSINESS CORRESPONDENT: Hi, John.</s>BERMAN: Bulls, bears, bulls.</s>ROMANS: Yes, yes, right? Investors return from this long weekend to a new trading month with stocks really close to records highs. The bull market is now the longest ever after the strong summer, but September, John, is historically challenging for investors. Since 1950, the S&P 500 has dropped a half a percent on average in September. That's the biggest average decline of any month. But, look, that's just an average. Last year the S&P gained in September. Still, there are some challenges ahead here. Trade disputes still a major issue. Will Canada join the new NAFTA deal? Officials from the U.S. and Canada will meet again tomorrow. It's critical here. Both sides claimed progress last week, but then failed to reach a deal to join this preliminary agreement, this framework with Mexico, amid the leak of a comment from a "Bloomberg" interview where President Trump where he said the U.S. was not giving up any concessions at all to Canada. The president this weekend again threatened to leave Canada out of the new deal, but the Trump administration has notified Congress that it plans to act in 90 days, which leaves the door open for Canada joining if the two sides can agree to terms. John.</s>BERMAN: All right, Christine Romans, thanks very much. We're waiting to hear from Democrats on the Senate Judiciary Committee. They're holding a news conference in just minutes. This in advance of the hearings for Brett Kavanaugh. We'll take you to that news concerns very shortly. Stay with us.
