We were buying them a few years ago at half price. We're still buying, but will take a more defensive posture soon. We're very well this could be Oct of '87 or Mar of 2002, but it doesn't feel that way to me. My crystal ball, though, has been very unreliable.

The fed's has nearly emptied its tool boxes to pump up the economy. Since the subsidized home entitlement boom, then bust, it has achieved slightly above a stagnate growth rate.
They say, “Don't fight the fed. Savers will suffer. To much uncertainty for longer term planning. You just need to invest in riskier short term things. It is the new normal. You can't lose if you can get your money out prior to the sudden burst.”
We live in interesting times. Good luck.

It does feel a little like October of 1987 and like when the NASDAQ hit 5000 in 2000.

I agree. This feels like 1986 or 1997. It feels more like '97, but I was 11 in '86. I just got interested in investing in stocks in '86, so I learned about market crashes right away.

Thus it is different. It is far more precarious.

It is different this time. There was good reason for the financial surge in the 1980s. Now the stock market surge is purely because there is no good place to get a return on investment right now. With effectively zero interest rates on T-bills, saving is severely discouraged, whereas back then at least you got 8% on a conservative investment.

At least you got to buy stocks on sale.
