Nearing Retirement? These Stocks Are as Safe as They Come

Just about everyone is familiar with Walmart (NYSE: WMT). Despite its massive size, Walmart is still capable of growing at a respectable clip: In its fiscal third quarter, sales at stores open for more than a year jumped by 9% year over year, with grocery sales rising by 10% as the discounter took market share from traditional supermarkets.
