Stochastics are a widely followed technical indicator....over 80 is considered overbought and suggest a potential downturn in the PPS, under 20 conversely suggest oversold suggesting a potential rebound.  They can't go higher than 100 or lower than 0....however I have see stochs get to 100 and stay there with a stock price continuing to climb, or at 0 with a stock price continuing to fall.  Nothing is 100% however,  and something game changing is always possible.....either positive or negative.

With RVX's chart we have stochs down at 2 fast and 6.55 slow... so there's not much room left to the down side from a technical perspective.  Something to look out while we wait for all manner of fundamental data....approval of the HL PP, the FA, another DSMB update....and goodness knows what else.

In copying and pasting it seems to give me the default chart with RSI (Rising Strength Indicator) instead of Stochs...ah well, beggers can't be choosers.  And its candlesticks instead of the lined graph....
