The stock market came into the Thanksgiving holiday in a very strong fashion -- continuing the strong rally that has taken place throughout November. A move above 3644 would be into new all-time intraday high territory. Once $SPX makes that move, there is no resistance in the traditional sense.
Meanwhile, on the downside, there is support just above 3500. A close below there would be very negative, for it would place $SPX back within the old trading range.
The broad market, as measured by $SPX, finally reached a new all-time closing high this week, at 3626 on Tuesday, November 16th. It was unable to hold that level and has now fallen back a bit. In fact, it has closed back below the old September highs of 3588. That in itself is not a problem, but if $SPX were to close below 3500, that would be bearish.
Last Monday, the COVID-19 vaccine new caused $SPX to gap up 135 points on Monday's open. That was the largest percentage gap to a new all-time high in history.
As traders know, there's an old adage to "sell the news," especially if there has been anticipatory buying before "the news." And they did, drving $SPX back inside its 3200-3600 trading range.
Election-related or not, the move from the bottom to the top of the $SPX trading range in just four trading days was impressive. The trading range extends from 3200 to nearly 3600 (the all-time highs at 3588). The recent moves have pretty much obliterated what had been a support and resistance area near 3400-3430, so the edges of the range itself are the only meaningful support and resistance currently.
The selling that began with a modest overbought condition on October 12th has snowballed into a major decline, capable of testing whether or not a bull market still exists. Now the only remaining near-term support area is at 3200. If that gives way, a pattern of lower highs and lower lows will be in place, and that is the mark of a bear market. That would be a game- changer.
