Life insurance is potentially the sector which will experience this kind of margin expansion over the coming decade. Most insurance companies presently have wafer thin margins between 2% to 4%.
Even a meagre 4% revenue growth at 6% margin will make their EPS zoom up by 300%.
Presently all Insurance stocks are fully valued (i.e 4% margin priced in but 6% margin not priced in)
Someone who enters now will ride the expansion from 4% margin to 6%. Those who had the foresight to enter at half the rate in 2020 March will get a 6x bagger when EPS goes up 3x
Additionally, Insurance companies reinvest the premium corpus accumulated with them which creates a secondary revenue stream with zero added expansion cost. Very high operating leverage business model and an under-penetrated sector (75% Indians don't have insurance cover).
