Blackberry (BBRY) has been retreating after a very sharp bullish swing from March through May. The retreat as we can see on the weekly chart has been sharp as well. But I think there will be support soon.Blackberry (BBRY) Weekly Chart(click to enlarge)Sideways Market:- It should be noted that shares of BBRY in recent years have turned from a bearish trend to a sideways one since 2014. - So, it should not surprise anyone if price does creep back towards those lows around 5.50-6.00.- But, I think we should also consider some support factors as price retreats towards 8.50.Support:- We can see that between 8.00 and 8.75 is a support/resistance zone. - The 200-week simple moving average (SMA) is right around 8.50.- Also, as the RSI nears 40, a bullish market should pull back up. - Yes, the support here would represent a market turning bullish, and we said the market is sideways, not bullish.- Therefore, this is an aggressive bullish outlook based on prevailing price action. - Perhaps, that means upside will be limited. Whatever happens afterwards, I think we will see some reaction here around 8.50, whether it be a temporary bounce to 10, or the pivot to a bullish swing to test the resistance around 12.00 again.
