@MrMoneyMustache233391 - I'm sorry my first comments caused you to get jumped all over.
My experience has been that most of the large cap companies owned individually underperform the index. I learned this the hard way over time. You just can't predict long-term changes accurately every time.
I owned GPC, a long, long time large cap S&P 500 dividend aristocrat blah blah blah. Office was three miles from my office, great management. It did okay, but the solid leaders retired, new ones came in, and they couldn't execute on acquisitions and blew a bunch of shareholder money. Their business also got amazon-d. If I had owned the index, I would have participated in the companies beating them.
Same argument goes for long-time Disney shareholders. Its a great company, but it seems to move in opposite directions with Netflix. Own the index, get both.
I get the appeal, I was above 10% concentrated in Costco at one point in 2015, was buying it in 2012 and it doubled in 3.5 years. Then I kept holding it, the returns reverted back to the mean or to index +/- a couple of percent. I have another big position in a mid-cap restaurant stock, great company but the sector is being pummeled.
It can be a fun game, but understand most of the people around here are more about life philosophy. Reducing the number of decisions you have to make in a day is a positive, especially when those decisions are statistically shown to underperform over long periods of time.
