<prompt> Human: Currently a 43 year old Male, unmarried, no dependants. 250k in my 401k, with 125k of that in my companies stock. The stock has been doing fantastically for many years, going from about 38share when i started to a current price over 350share. I deversified most of it once 5 years ago, which turned out to be a bit of a mistake as the stock was only at 150share then, but I did okay with my choices and still retained a good bit in the main one, so Im not going to complain too much. Anyway, with so much of my 401k portfolio invested into one stock, should I be considering diversification again? If i think the company is going to remain at the least, pretty stable, more likely fairly successful, is it okay to stay so narrowly invested. I get good, if not super dividends, and am continuing investment through the max company match. Assistant: Sell all the company stock sitting in the 401K. Today. Put none of your own money into the 401K plans company stock option. Each time the matching contributions come to you in the form of stock, sell them.Human: Rather negative arent you.  <response>: What I am is trying to look out for you.You depend on your company for your job. You have significant assets tied up in company stock. You are putting more than half your eggs in one basket. Extremely dangerous.Have a nice day; we are done here. Good luck.
