many investors are frustrated that they can only get a little more than 1% return on safer invetments, this has created a bubble of people investing in stocks with 3 to 5% yields evn though the stock might not be making any money. there is always someone waith to slaughter nieve investors trying to eek out a couple extra percent on investments. NEM is a great example of a yield bubble stock.
I don't see the yield changing for an investor that buys at the low. That is why payout history and % payout of profits is important. If you buy NEM at $30 and get 30% of earnings paid pack to you every year, that doesn't change what you paid. Would you really pay 25% more for a stock for 2% more "yeild"
The real danger is if the price goes down after you buy.
