Friedcat said a few months ago that he would like AM to achieve an annual yield of 5-15%. The 'glory days' of huge dividends are over. I'll have to dig for that post.
That doesn't make much sense. It's up to the market to price the shares, which will determine their yield percentage. Targeting a particular rate of yield is not something FC can control unless he can set the share price.
In general, yield will be high when there is not much expected future growth. Yield will be low when the market is expecting future growth in dividends.
Look up when exactly FC wrote that and think that he intended to maintain divs at 5-15% a year.
