<prompt> Human: Hi everyone,I have a little under 10k in my ESPP fund. The company is C. R. Bard, stock symbol BCR. I get the stock at a 15 discount. The stock is at an all time high, and been constantly increasing since i started in 2010. Ive been doing a little research and everything I see says to sell right away, so now I feel like I should sell mine. I know it is dangerous to have all my money in one stock, but I would hate to sell it and have it continue to rise.Another concern is what if it splits? It split a few years ago when it reached about 100 a share, and now it is almost double that. For some additional info, I have about 40k in my 401K fund.  <response>: Yes, it is always a good idea to diversify away from individual stock holdings. ESPPs are best when treated as income supplements anyways. I would hate to sell it and have it continue to rise.Youd probably hate to keep it and see it crash even more.
