Through this downturn I've seen so many analysts suggest stop losses as a way to minimize risk. The strategy works like this. Your stock falls bellow the amount you are willing to lose then you sell. This to me sounds like buy high and sell low which is the exact opposite of what you want to do if you want to make money.
So alternatively, I wondered, if you are concerned about losing money why not buy some kind of option (a "put" to be specific) that let's you sell at a given price. That way no matter how far the market falls, you have the option of selling at the price you bought the option for. Anyway, when I looked at the numbers for one stock bellow and this strategy didn't seem too hot either.
So how much will this insurance cost you. Well, I chose IBM as a random stock. Here is the current stock price:
Last: 117.09 Change: -0.54 Volume: 5,120,042
Here are the quotes on puts:

The option contracts tend to last for about a month. So say we don't want to lose more then 20%. Then our stock should not fall by a factor of more then 0.8 per year or (0.8)^(1/12)=0.9816. The current price multiplied by 0.9816 is 114.935544
The closest strike price to this is 115.00. The asking price is 2.100.
The asking price for this option is 1.8 % the price of the stock. Therefore to protect against a 1.8% loss in a month we would need to buy an option worth 1.8% the value of the stock.
This doesn't sound two effective, unless you consider there is a good chance of the stock jumping much more then 1.8% in a month. Not sure when this would happen. Maybe in a rally after a dip. Maybe if I consider some other scenarios it might work better.
