<prompt> Human: Its irrational to buy a handful of stocks without proper research. Thats what I did...Is it irrational to sell them once you realise it is irrational, to correct the irrationality, or is it doubling down on the irrationality. Also, I made a heavy loss of 20 of my networth on each of them :P  <response>: I once read a quote by Sam Zell that said:Any time you dont sell, you buy. That really stuck with me, but I have a hard time getting the point across.Ill try anyways.If you had 100,000, would you buy 100,000 worth of shares in company XYZ? Many times people will say no.But then you ask if you had 100,000 worth of shares in company XYZ, would you sell them? They still say no.But at any given point, weather you have the cash or the shares, you have the choice between the cash and the shares. If you wouldnt put the cash into the shares, why would you leave it there?
