"Lucent" is a bad word with me right now! Let's just say I could have sold at the high of around 84, but, instead, continued to buy more and more as it went down. I kept saying to myself, "This is the bottom! Buy!" Oh well, I have faith that it will go up a lot (although not in the immediate future).
With investing, the important thing to remember is "don't put all your eggs in one basket." Right now real estate is WAY too high in Southern California, so I'd wait until it goes down before you buy. Because real estate is so high and interest rates are so low, I'd recommend an assortment of S&P 500 stocks, but there is no guarantee (e.g. Lucent).
