You need to understand that history never repeats itself exactly but we can see what happened back then and we can see what it is happening now and we can find some common ground and some differences that allow us to infer a massive bull run is on the cards.

However we must remember that predictions can become irrelevant even seconds after they are posted as the markets and the world itself move incredibly quickly, for example the bull market that we were expecting was delayed because of the pandemic and the crash we saw when people finally realized the covid virus will go global, if something like that happened again the market could crash even if its fundamentals are incredibly strong right now.
