The term "missing out" is essentially invented by analysts to create anxiety for novice traders.
For real traders, there is no such thing as "missing out."

Those who can trade have strategies and naturally know—when to test with small positions and when to enter with large positions.
The focus of speculation has never been whether or not to get on the bus, but rather how to limit risk.
