PLTR or MCO Palantir or Moodys

Hey guys so I currently invest in PLTR. While the stock is down my portfolio consists of a lot of growth stocks which are obviously volatile. My goals are long term but I was hoping to have more MOATS like moodys in my portfolio and has that less volatile more stable growth stocks which.. Out of my stocks the one I’m willing to remove it PLTR but having fomo about the potential for growth. Palantir really is probably one of the best software company out here in terms growth, retention etc. What do you guys think swap or PLTR for MCO in a portfolio with mainly growth stocks? Thanks
