I think it will be a great time to invest. Soon.
I would suggest reading up on Floyd Odlum, he set the standard.
I agree. Personally I dumped everything I had in the middle of February and was in cash until 9.15 when I put some into treasuries and other govt backed obligations. Have made a bit of money there and increased my income a bit (I'm retired).
Lately I've been contemplating getting back in slowly, perhaps over a six month period. I personally prefer Mutual Funds and in particular balanced funds. I have no problem paying the management fee since the folks running the fund know a lot more then I do. My current favorite is Vanguards Wellington Fund (VWELX). Still I'm hesitant about sticking my toe back in although I realize nobody rings a bell to announce a market bottom. I had been fully invested in the market since 1980 and never sold anyhting even in 1987 when it all came apart (DOW down 21%). This time though I kept having this nagging nervous feeling that something bad was coming down the road. Mostly what mad me nervous was that no one seemed to have a clue what was actually going on and what if anyhting could be done. The worst thing for the markets always has been uncertainty and in this instance the levels of uncertainty reached highs never seen before. The Chinese have a saying, "May you live in interesting times". We are certainly doing that. Unfortunately interesting doesn't always mean good.
