dndn, I hope you are kidding, no single stock should ruin anyone's life or portfolio. I've been in the commercial real estate business many years, and like PLD's long term prospects. This company has a number of assets it can draw upon when it needs cash, and focuses on industrial real estate (big, simple concrete boxes) rather than insane malls and strip centers (what were all those retailers and retail developers thinking?). But it could be a bumpy short term ride. I rode PLD from 6.50 (where I bought) to 2.50, to 11.00 (where I sold) back in the fall. It is a manic stock, just like the rest of the market, but more so. I've always been more of an investor than a trader, but this market has taught me that it pays to trade at this point in history. Long term I think PLD recovers, so be patient, but expect the inevitable low points on the journey.
When I first got into the market back in 98, I was trading then I decided to be a long term investor and got screwed. In this market or any market for that matter its best to be a trader and dont fall in love with any stock at the end they will cheat you.
