Bank names have been down this year and Morgan Stanley $MS is not exception. Price peaked in March around $59.40 a share, and is now trading just above $40, threatening to break below a key support here.MS Weekly Chart(click to enlarge)Support/Resistance Pivot at $40:- The weekly chart shows us that the area around $40 was a key support/resistance pivot going back to 2015, when it was a critical resistance.- Then, in 2017 it became a strong support that launched the move from $40 to $59.40. - Furthermore, the 200-week simple moving average (SMA) is right here. Strong Support for a Bull market, but...downside to $33.50?- These are all strong support factors for a bullish market. However, with the bank names general bearish and the general equities market also bearish, I don't think we can rely on support here other than in the very short-term.- I would limit any upside here to $44, about a 10% rebound.- Instead, I think there is more than 15% more downside towards $33.50-$33.60 area.- As we can see on the weekly chart, price will be meeting a previous pivot and a rising trendline if it comes down to this area. - Furthermore, the RSI would likely fall back to 30 or below. - Then, we can start considering the long-term bull trend. But for now, it looks like the focus is on the medium-term bearish trend of 2018 that will likely spillover into 2019.
