Shorting has its place and can bring you alot of profit. I think its only for the very experienced though!

I've also heard of it being illegal in some places, simply because by shorting the stock you will pull down the price and thus, when in large enough quantities, you can cause some sort of a panic. You know the drill, you sell enough to make the stock go -2% and some people will have their stop loss activated, others will sell because they think it's going to go lower etc.
Then again, the same exact thing happens if you buy with a lot of money.. so I don't really see what the problem is.
I've always been interested in day trading, but have not yet gotten up the guts to do it. This sounds a bit complicated for a newbie like me. My initial strategy was to simply learn how to read stock trends in order to learn how to pick a stock that looks like it's on the rise. Buy some shares there and sell as they hit their peak. Of course this is all about timing and you have to make sure that you cover your initial investment plus your trade commission you have to pay, but I think that this might be the safest bet. Shorting stocks sounds a bit more aggressive than I am ready for just yet, but it does sound interesting.
Personally I do not have a ton of experience trading but do have some. Issue with shorting stocks is that you have the potential to lose a lot more than you do when buying. Because when buying it can't go below zero, but when shorting the company can grow to more than double than the original, so you can lose more than your original investment. Personally I'd prefer a put (option of a short) over actually shorting, and do it for the short term, about some bad press release or something. That was the only time I experienced benefit from rooting against them. But like I said some people on here have much more experience at it than I.
I never sell any stocks but my father always do like this, he always short stocks and he also get profit by selling the stocks. But I know very little concept of borrowing the concept like to sell it and buy it back and give it back the broker easily understand this concept. So when you buy and sell when the dividend is paid an individual have sold the stocks and the company pays to the purchaser of the stock.
