the ominous signs of crash is making me uneasy. (orange man alert)

Have been in market since 2015, seen the carnage that orange man did specially in small and mid cap segment. was sceptical since he won but day by day it seems history is going to repeat itself. we are going to witness another half a decade of small and mid cap underperforming almost exactly like the last time. feeling unfortunate with the timing of my entry into markets. anyone has some uplifting news which negates my views?
