Home Depot (NYSE: HD) and Costco Wholesale (NASDAQ: COST) are two stocks that have slowly and securely grown and turned $1,000 into more than $10,000. Costco: 18 years, 1,200% Costco is another stock that doesn't make a lot of waves but racks up gains over time. That's because customers seeking low prices as inflation sends prices higher flock to Costco's discount stores.
