People with high risk tolerance aren't limited to only those professional or experienced traders. There are those beginners who are totally aware of what worst might come ahead while learning the ropes of trading. Of course, lossing some is considered as "automatic" when you're on the basic course of trading, only you're lucky if you don't lose too much, because there are those who are talented enough to analyze the market movements, signals and TA's during the early stage of their trading careers.
However, holding is simply easier than day/short trading.
