Limiting portfolio risk to extreme "black swan" events.

I am not looking for a systematic way to call market tops or bubbles, I don’t think they exist.

I am far more interested in finding ways to limit the exposure on the downside of a portfolio due to “black swan” events. The expression made famous by Nicholas Taleeb in his book The Black Swan. Such events would be defined as
  • unlikely events with disastrous circumstances,
  • bursting of bubbles, or
  • other low probability events that could have disastrous consequences on a portfolio.
Also,  such thing as a perfect hedge that protects the downside and retains the potential for upside gains… is either non-existing or very rare.
