S&P 500 Long-Term view (as per 22nd Aug. 2015, post-market-close)
For this purpose I added the weekly SMAs for the following periods: 15, 30, 60 and 90. As per weekly close (closing as per Friday, 22nd Aug. 2015), the SPX closed little above 1,970 points with a long red candle.
In order to remain in the medium- and short-term uptrend, the SPX should stay, according to my current assumptions and best-guesses ABOVE 1,925 points. As there is not much room left => a sustainable bottom should be established near the current area.
