I guess it is how much you can buy and expect on dividends. AWP goes for about $5.50. while RWR goes for about $55.00 & RWX goes for about $35.00. If you only have so much money to invest you can but more shares of the lesser priced AWP. You can have more shares and generate more monthly dividends and hopefully wait for the market to up the NAV and have a double benefit.
