Should I dump my mutual fund to buy Berkshire-Hathaway?

This is a follow-up to my previous question. I am not impressed with my Income Stock Mutual Fund (USISX) and want to dump it to buy BRK-B. I've done the research and BRK-B has outperformed USISX for years. It looks like a good buy to me, I just want some other opinions.

I'm already invested into an S&P 500 fund. I just am not impressed with my Income Stock.

check morningstar.com fund screener (free) ..... you can see which funds have a great track record over time ie EKWAX >20%/yr avg over 10yrs! , up 5% this year already when most are negative, or assuming you'll get in on a dip CGMFX, which has an even better long term performance, but down 12% right now.....I don't see anything wrong with letting the Buffet team manage a piece of your portfoloio, just know BKR-B has 10yr avg of 9.8% and down 4% this year.....whatever you do, you need to get out of USISX which is one of the >80% of funds which underperforms the mkt

If you have less than $500,000 never buy individual securities.

Might I suggest Vanguard S&P 500 Index fund.

Diversification is critical, especially now with the market in an unusual state and traders are edgy.

It sounds like you have done the research already. Do what you are comfortable. It really is that simple.

AND if Warren Buffet had waited until he had 1/2 million to invest in individual stocks. We wouldn't know his name.

Again do what you are comfortable with.
