to me everything has a risk factor to it.
leaving your money in tin cans in the backyard is risking that you'll loose money with inflation.
buying BP stock, you risk loosing when an oil well blows up
putting money on Miami winning it all is another risk
the key is judging the risk and putting a value on it and then finding an opportunity to take that risk at a lower price.
you can buy:
a truckload of tv's worth $10,000 for $5,000,
CSX stock worth $85 for $75,
New England Patriots to win it all worth +675 for +1500
makes no difference to me, I'm looking for the highest return for the lowest risk...
gambling is risking more than you should because you think you can win
