Isaac Newton escaped a stock bubble with a profit
then watched his friends get richer and bought back in
that decision reportedly cost him £20,000
in 1720, the Cambridge professor invested in the South Sea Company.
he sold early.
the price kept climbing without him.
every new high turned his correct exit into something that felt like a mistake.
Newton returned with a much larger position near the top.
then the bubble collapsed.
nothing about the company had improved enough to justify the new price.
only the crowd had become richer and harder to ignore.
before chasing something u already missed, ask:
did the opportunity improve, or did watching other people win become unbearable?
Newton understood gravity.
the market taught him that envy pulls too.
