Merrimack Pharmaceuticals $MACK was bearish in 2018 and has been in a long bearish trend since 2015.MACK Weekly Chart(click to enlarge)Bearish Trend:- We can see from the weekly chart that price has fallen tremendously since 2015. - It might look like price action has flattened since 2017, but the decline has actually been worse. For example, price fell from almost $140 to $30 from 2015 to mid-2017. That is an almost 80% dip.- Then it fell from $30 to a low of $4.00 in 2018.That is more than 86% dip.- Now that we have established the long-term trend, we should probably be cautious when looking at a bullish outlook.- Let's get down to the daily chart, where we DO indeed see a possible short-term rally ahead as price appears to be in bullish reversal.Bullish Signs:- Price has been rebounding since cracking $4.00 in October 2018. - Note that price has come up above the cluster of moving averages, mostly importantly the 200-day SMA. - When price came up to $7.50, a previous support, it retreated. This shows that the market is still bearish.- However, on the way down, price held above the 200-day SMA. Also, the RSI didn't fall back below 30.- These are signs that the market MIGHT be developing a short-term price bottom indeed - that the bullish recovery might have another leg. Again, I wouldn't go against the long-term downtrend, so I am only entertaining the possibility of one more push, maybe towards $10.00.- If price can hold above $5.50, there is a chance. But a break below $5.50 and then the 200-day SMA will likely spell the end of the recent recovery. Then, the prevailing bearish trend might take over again. MACK Daily Chart(click to enlarge)
