NEW YORK (TheStreet) -- In later July, as Apple (AAPL) - Get Report was in the $130's, the decision support engine allowed the analysis posted in this article. It showed a forecast for the shares to fall in price into the $70 +/-$15 zone, bounce $30 +/-$5, then fall again toward $65 +/-$10.

This is the updated monthly bar chart of the progress Apple has made along the path that we showed with blue arrows (then), which the crowd of apple eaters has been following closely.

Notice that the bearish divergence sell signal (shown by the red lines above the higher highs in prices opposing the declining red lines of lower lows in stochastics) has led to the "free fall" conditions in the stochastics, which dragged prices (since the decision support engine warning on July 22) to $92 so far -- nearly touching the upper end of the forecast for an initial low. The bounce since, which is the corrective bounce that the first blue arrow contemplated, has occurred already, and is likely complete, or nearly so.  

This leaves little room for the imminent Apple unveil to goose prices further, causing the objective decision support engine to reissue its warning now. The answer to the decision support question "If I have no money in aapl shares, would buying or selling actions be indicated at this time?" is clearly that selling actions only are indicated here.  

Notice the similarity of these same conditions back in 2012/2013, when the selling didn't end until the stochastics dropped from the extreme overbought 90% threshold, all the way down to the extreme oversold 10% threshold. That leaves plenty of room in the coming days/weeks for much greater price damage than has been seen so far. The decision support engine warns that either prices are about to fall in a hurry toward the $70 or lower area, or will erode over many weeks/months toward the sub-$70 zone.  

Therefore, if you're long and happy since the $92 spike, selling actions should be set up as sell stops at the $108 level, or upon a spike into $120 resistance from the 50-day moving average crossed below the 200-day moving average (some call this a death cross), as well as the resistance from the upper Bollinger Band. If you're flat, selling actions can be used to establish short exposure along these parameters. If you're already short, the decision support engine suggests using selling actions to maintain or add to that exposure, according to these parameters.  

Nothing personal Apple. I use an iPhone 6 Plus. It's just (objective) business!
