Loading ...If you want to make it more difficult for hypothetical shorters to short the companies you are invested into, just put a sell order on your position at a very high sell price so that your broker can’t borrow your shares to shorters (most of the time, it depends on the internal rules).
For instance:
UUUU: a sell price above 15$
DNN: a sell price above 5$
URG: a sell price above 4$
NXE: a sell price above 15$
and you will be fin for a couple of weeks
