I know you are trying to quickly make up a loss, but you are really swimming against the tide trying to compete with professional stock pickers.
I urge you to just buy the index (or Berkshire!) and get on with the good part of life.
Charlie, I have to agree with this. Buying the index is of course Buffet’s advice for the no-nothing investor. But, as so many here have trumpeted ad nauseam, the S&P 500 is a bit long in the tooth, and needs to revert before it is attractive again. I have a huge slug of my net worth in Berkshire, going back to 97 or so, and have added all along the way on dips…and I’ve never sold a single share. I think that might change for me in the not too distant future.
Putting your toes in the water with a little Berkshire is a good start. But, don’t get crazy like me! Like you, I have a stash of cash that I fully intend on indexing at some point as a barbell of sorts against my BRK. I may in fact begin to diversify away from my over concentration in BRK soon and sell a bit as it reaches a higher valuation, much as Jim and others on here did recently, by taking some off the table as it approached 1.6 BV. This is something I thought I would never ever do, but I’m phasing into the last third of my life, so I’m not so sure that I could ever be like Warren or Charlie and go all in. So, I’ll put some of those proceeds in cash, and await for an opportunity to redeploy in an index. I don’t think you’ll have to wait a decade though to move into the indexes, so just be patient and sit in cash for now, and wait for occasional, but meaningful downdrafts…that’s not really the same thing as true dollar cost averaging, but it’s a way to capture some value as you incrementally build a position in the indexes over time.
Meanwhile, if Berkshire and Indexing will be your primary investing focus over time, then stay here on this forum. But, I also highly encourage you to slip on over to the bogleheads.org forum and explore all you possibly can about indexing. There are a lot of very smart, but also not so smart, folks over there. You’ll find a wealth of information from others who have made the same mistakes we all have. In spite of their professed disciplined approach to indexing(stay the course), you’ll gain an insightful appreciation for their wavering ambivalence, second guessing, and shifting convictions about what is the best asset allocation model to use. You’ll hear their regrets about loading up on bonds amidst a rising interest rate environment, whether or not international equities have a place in one’s portfolio (and how much), and the endless ongoing debate over cap weighted vs equal weighted stock indexing. You already know how Jim feels about RSP and QQQE, so, go get the other side of that debate — and yes, there is even extended discussions in various threads over there about BRK vs Indexing. It’s a good place to figure out where you want to go…I think you’re on the right track, but don’t rush yourself. Get comfortable, and educate yourself as you have been doing.
