Is that it for the Nasdaq 100?- Index reverses after reaching key level

As covered here yesterday afternoon, the Nasdaq 100 did meet its final technical reversal level at 19,924. In fact, it just surpassed it, when it reached a session high at 19,938, but in truth that is not actually of much consequence in the greater scheme of things. So, the slide that followed saw the index dump to a low at 19,459. It later closed 333 points lower, at 19,491. Overnight a gain in the Nikkei 225 has helped to lift the Nasdaq 100 futures and right now those are pricing a a reopening at just above 19,600. However, the question to ask right now; is that it for the Nasdaq 100? Has the index rebounded enough, or is there more to come? Much could depend on what the Fed boss, Jerome Powell has to say later today, when he addresses the audience at the Jackson Hole symposium. There is surely more to add on that as the day unfolds and then what the future holds for the Nasdaq 100 by the close tonight
