This week I finished the book "Capital Ideas and Market
Realities" by Bruce Jacobs. This was a set of essays
about modern finance. Bruce was complaining about
"Portfolio Insurance". This is a strategy to
move from stocks into safer cash or bonds, when
the stock market starts to go into decline. This
is meant to help stop loses. This is theoretical
idea behind automated selling that was a cause of the stock
market crash in 1986. I am still learning the financial
jargon, but the book was a good introduction to
the ideas of financial mathematics
