I highly advise against averaging down on a losing position. Especially when dealing with the aforementioned bearish hypotheticals.
While SNS is a great company, you still have to consider risk management so you are not a bag holder with a heavily depreciated position. This limits your ability to be liquid and also limits any opportunities to trade the volatility (unless you have other accounts with cash in them).
If 100SMA is breaking, this is a bearish signal. Not something to buy into unless trading and are looking at more micro time frequencies (1 minute - 1hr trends).
