What is a recession?

A recession is a prolonged economic contraction: falling GDP, rising unemployment, consumption and investment stalling.

The most used technical definition: two consecutive quarters of falling GDP. In the US the official referee is the NBER, which weighs employment, income and production. Recessions are a physiological part of the economic cycle: since the 1950s the US has been through about ten.

For stocks the relationship is treacherous: markets anticipate. They often crash before the recession is declared and climb while data still looks terrible — buying "when there's blood in the streets" is easy to say, brutally hard to do.

Concrete example

In March 2009, with US unemployment still rising and headlines apocalyptic, the S&P 500 bottomed and began a 400% eleven-year climb.

Frequently asked questions

Can recessions be predicted?

Poorly: the most famous indicator (an inverted yield curve) has preceded many recessions but with unpredictable timing, and sometimes falsely.

What should you do with your portfolio before a recession?

The honest answer: don't try to guess. Diversification and a long horizon beat market timing almost every time.
