My interpretation is that if you find yourself making decisions based on worrying about missing out on future opportunities due to rising prices (whether in goods or investment opportunities), it's probably a pretty good indicator that you might be getting caught up in bubble market mentality
A reasoned, well thought out, detached assessment of the situation may be what is most helpful before making any decisions.
Personally, my worst financial decisions have come from feeling rushed, panicked, and worried, and trying to outsmart the market. My best ones have come when I recognize those feelings and decide to wait to make a decision until I feel I am in a more stable environment and can feel clarity about the situation.
