<prompt> Human: My wife and I have a mix of Roth IRAs401ksTaxable investments, of which 4337; are AMZN stock. We do not put any more money into single AMZN stock.From a net worth standpoint, its about 2537; since we own a house as well. I understand that the typical rule for owning a single stock is that it should not exceed 537; of your portfolio and the risk of owning so much of a single stock.Would you actively divest or just continue contributions to other investments?We are 27 and have no children, if that makes a difference to the discussion.  <response>: Yikes. I think thats way too high to wait for other investments to grow. I would do some selling now to get it back to a reasonable level. Youre in luck since the stock is doing great right now.
