News that the United States and China had brokered a trade truce over the weekend got the ball rolling strongly on Wall Street to start the new trading week and month on Monday. In fact, within minutes after the open, the Dow Jones Industrial Average was up more than 440 points. However, that would prove to be the high-point for the day, with the stock market staying positive, but not building on that early advance. In fact, there would be some whittling away at the gains, with the Dow finally ending the session up by 288 points, with the intraday advance at one point descending to fewer than 150 points.

Then, there was some serious rethinking of the trade truce between the two economic powers by Tuesday, and stocks began the latest session with sharp reversals. To be sure, Tuesday's caution did not fully counter Monday's optimism at first. However, there was enough morning selling to bring the Dow down by more than 300 points. The other major composites fell back in tandem, with the small- and mid-cap indexes suffering the most. Worries about slowing growth in 2019, with news of an inverted yield curve, in which short-term interest rates trade above longer rates--a suggestion of a business reversal--weighed on sentiment, as well.     

As the afternoon began, there was a big selling wave that engulfed the equity market very quickly, driving the Dow down briefly to a loss of more than an 800 points before we moved inside the final two hours of trading. Specifically, the Street was worried about a bond market phenomenon known as an inverted yield curve signaling a possible economic slowdown or even a recession. The financial stocks led the downturn in the market on those slowdown fears. Not only were there fears about a flattening or inverted yield curve, but there also were worries that a long-term trade deal might not be brokered with China, after all. 

Long-term interest rates, meantime, continued to fall, with the return on the 10-year Treasury note easing back to 2.92%--or some 30 basis points under the yield in place just a month or so ago. Although such a decline would normally be good for Wall Street, the rationale for this drop--a possible slowing economy and narrowing profit returns--is not encouraging for investors. Once the sellers amassed, the market would stay lower for the rest of the day, with major declines across the board. Only the VIX volatility index would show significant strength. 

Regarding China, the United States and that fast-growing nation had agreed over the weekend to hold off on any additional tariffs on each other's goods in January. But there since has been some confusion as to when the truce would begin. So, there was a loss of confidence taking hold just one day after the formidable rally and a day ahead of yesterday's stock market closure for the funeral of former President George H.W. Bush. The market will open for trading later this morning following Tuesday's severe setback. As to the equity market, it would end near the day's lows.

In all, the Dow would end off 799 points, to just over the psychologically important 25,000 level; the S&P 500 would lose 90 points, to end just at 2,700; and the tech-driven would tumble 283 points. Worse, the small-cap Russell 2000 shed more than 4%. Many more stocks fell than rose on the day in one of the most severe setbacks during this long bull market. Now, following the one-day hiatus in trading, we look out at lower price action in Asia overnight and to sharp declines in Europe so far this morning. Moreover, after a day that saw a reasonably positive report on non-manufacturing activity issued, the U.S. stock market is set to open notably weaker.       

Where we go from here will be telling in the short run. We have had both sides of the coin so far this week, with the early euphoria on Monday followed by the major selling on Tuesday. Will we get a Santa rally? Things do not look all that promising now, but the situation can change on a dime, as we have seen so far this week. The next few sessions could be setting the stage either way. Stay tuned.
