Blue-chip stocks are popular because they typically have a decades-long track record for earning. "Blue chips" derived their name from Poker, where the most valuable playing chip color is blue.

Blue-chip stocks are not flashy, but they have solid balance sheets and steady returns.

Dollar-cost average: This sounds complicated, but it’s not. Dollar-cost averaging means investing a set amount of money at regular intervals, such as once per week or month. That set amount buys more shares when the stock price goes down and fewer shares when it rises, but overall, it evens out the average price you pay. Some online brokerage firms let investors set up an automated investing schedule.
