Targets can change
on technical indicators as data changes daily based on price action.
To answer your question, I personally do not see Nugt going to 50, unless there is some type of extraordinary event that takes gold to new highs, though very unlikely. I would be a seller of Nugt in the 30 area on any short term bounce at the current price level, that is of course, if/when it bounces. If Nugt trades to the 20's for example, the sell target would change also.
