Sure, you are right, but even with that definition somebody could have just bought Apple/Google/Amazon/Facebook/Tesla/ other high growth stocks/Bitcoin 10 years ago, and just waited. I see more of this kind of active investing happening (people reading Tesla blogs and going to meetups as an example, deconstructing software updates to see how the models are being ported 1-by-1 to the new framework. Financial advirsors generally don't do this in depth due diligents for products (or at least I haven't met any). As an example I read through a part of the Bitcoin source code to see how well it's written before investing in it, and I haven't seen any financial advisor who even looked at its github repo, and they already have opinion on it.
