Positives: Peter Lynch explains well how the lambda Péquin can identify interesting investment ideas before Wall Street by his sense of observation, and it has, contrary to what he thinks often many advantages over professional money managers. The classification of actions by type, and the explanation on the ten-baggers of effect on a portfolio are particularly interesting.
Negative point: Plan a little messy, last a little old edition, and a lot of duplication with other books by the same author.
