Most professional bearish traders understand more how the financial markets work than their bullish counterparts.
Usually, they are sophisticated market players who can play the financial market game on any field. That is why I recommend that one really master the art of shorting financial instruments especially if one is dealing with a large amount of money.
The gorgeous advantage of selling versus buying equities is the speed of the reward because the price drops faster than it rises. One, two and three; and it is all done and dusted very fast. That is why a bearish investor should never sell if he or she has missed the best entry point.
Warning
Sell only after a rally to the edge, and common sense trend line is broken in a down trend. Be sure that the bearish trading signal is at a resistance level. If not, do not take it. Come out of the bearish trade as soo as the trading signal becomes obsolete. Do not chase the price down, but allow it to come to you.
The second advantage of being a bearish trader is that one will be laughing all the way to the bank if one is right; and others are buying. One can make money when others are sitting on their hands waiting for a new bullish trend.
The third advantage of being a bearish trader is that one can buy and sell throughout the financial markets' cycle.
One is more active, agile and prudent.
Really, in my opinion, bearish traders and investors are more prudent than their bullish counterparts because they understand that the markets can rise and fall instead of expecting it to rise non stop for ever.
