Looking at Avantis funds and ETF, none have an inception date before 2018 and many say 2022 and 2023. So nowhere near a long enough track record to establish anything meaningful.

I'm a lucky amateur at this game. I "discovered" BRK when the B shares were fairly new and put enough of my then tiny net worth to make me look smarter than I am. I hold shares in taxable accounts and in IRAs... I got fancy a few times in my IRAs and sold BRK when it was high and bought back shares when it was lower. I end up with about the same returns, with the leave it alone taxable accounts showing slightly better returns. It's taught me that unless I think prices are really way out of whack and that I will actually not buy back shares until they get ridiculously low prices that I'm not doing anything productive. In fact, I'm stressing out while waiting for that moment when the price is low enough. I always buy back at too high a price. I can't wait it out that long. I always feel like I'd better buy it back now because... when the stock price is high, it often goes higher. But not always. Same with the other way.

I'm not smart enough to grasp options. It takes up too much concentration on my part. I'm not a natural. Know your circle of competence, right?

I'm hugely invested in BRK.B but have been diverting other money to QQQE over the years for some diversification. Have a little Fairfax, Markel, Google.

Be kind and someone let us know when the BRK train has stopped. It's important to get off before it goes off the rails.

Cheers!
