<prompt> Human: A previous employer of mine offered a deal where you could buy their stock at a 20 discount. There was some cap on this, I think it landed around 5-10k.Whats a good guideline for handling deals like this? In theory, its a great way to make 20 returns, but its also extremely un-diversified. Not sure how to balance those concerns.  <response>: As long as there are not long holdings requirements it is fine to do this. Most people will buy in one period and then sell int he next, rinse and repeat on 20 returns, at worst maybe 15 returns. Still a good idea.
