From a trading perspective, you broke even on the decision either to buy on June 8, 2018 or sit in a money market fund earning about the dividend amount.
From an economic perspective, the companies in the DJIA have been buying back stock and increasing earnings since June 8, 2018, so I would argue buying it today is a better deal than buying it last year. You are now buying more EPS per dollar than you could have bought on June 8, 2018. Earnings, not market prices, are the fundamental underlying support for any 30+ year retirement withdraw strategy. The name of the game is to buy as much earnings and earnings growth as you can buy. it's good when stock prices fall because you can buy more earnings for less money.
If you are the type to sell covered calls, for example, you missed out on the money you could have earned that way by not entering your position on June 8, 2018. I don't know what option prices were like back then, but calls on DIA (price: $254.86) expiring March 30, 2020 at the 262 strike price sold today for $10.80/share. In other words, you could get paid 4.2% right now in exchange for being willing to sell your shares for a 2.8% profit, not including another 2% in dividends. So a 9% maximum upside and less downside than if you just owned the shares.
I don't think most people understood your question.
