to have a radio show called "real money" and i got a giant number of calls telling me to stop bashing enron. why? because the callers had a ton of stock in the company. i then came back and explained perhaps they needed to diversify away from enron. each time i did it i heard about how they got discounts or how such a great company was too terrific to sell or the fact is that it was done so much they couldn't sell. then one day it was gone many people have made this argument before and the company stock is still the number one investment. why? you probably feel like you understand the company you work for and the excuses that you're investing in what you know. i'm telling you, that excuse doesn't cut it. you've got to cut back. just cut it back tomorrow. here's the baht bottom line, diversification comes before everything else when you're investing. whether it's diverse portfolio or investment in your 401(k). never put more than one-fifth of your retirement money in the stock of the company you work for. just like i advise not putting more than one-fifth of your capital in any one sector. d
