S+P 500 posts a dally close below 6k after sellers stamp on rebound

Yesterday was quite a rollercoaster for the US stock markets. The initial fall to 5,977.83 (the low of the day) in the S+P 500 was then followed by a rebound to 6,031. If you care to look at a chart of the price action leading into and after the European close, you will see how it seemed to hit a brick wall above 6,030 and later fell back towards the lows ahead of the US close. The index later ended the day below 6k, closing 29.88 points lower, at 5,983.25. That marked a third lower daily close for the index. The S+P 500 futures are not much removed from that closing level just now but right now pricing a slightly higher opening. Important levels to note later on lie around 5,945. That is the price point of a rising trend line and the current 100 day moving average is around there too, right now at 5,944. On the topside 6k and 6,008 (50 day moving average) look like potential resistance levels when live trading resumes later today. The S+P 500 is right now priced to reopen around 5,985
