I think if it were me, I'd take out everything but the value of the original investment and look for your next great pick. A few reasons behind my logic. 1. ) You still seem to like it a bunch. If you bought $1000, 8 months ago, you still seem to think it's worth a $1000 investment today, so why not. 2. ) Being pragmatic, where can it go from here? MS Teams, WebEx, Facebook, Google Groups, etc. are all seeing where Zoom is finding success and trying to copy it. So perhaps this is a long term peak, maybe it's not, but the next tripling or so in value will likely be harder. Get your money while you can! 3. ) Covid-19 won't last forever, so this may be an all time peak as we go back to "normal" or people find other ways of dealing with this. 4. ) The anti-market timing people are often focused on timing the market perfectly. That's incredibly difficult as they've often demonstrated. However, decent timing of the market is often more than good enough. You're not going to get the absolute maximum gain that you could have gotten, but if you're within 10 or 20%, you're probably better off than many other strategies. Plus, you save the stress and time of trying to perfectly time things even though it's still an educated guess in the end. 5. ) No one's answer is going to be right as it comes down to how much you value the different outcomes of this decision. Choose what works best for you.
