Warren Buffet and Charlie Munger on shorting: https://youtu.be/GVtaKKn43M8 “It’s ruined a lot of people “ “It’s the sort of thing you can go broke doing”
E.g. consider Jim Chanos & Kynikos Associates. Chanos founded Kynikos in 1985. Kynikos has a short-only fund, a long-short fund and a 190% long/90% short fund (i.e. a +100% net long fund).
This FT alphaville interview with Chanos: https://www.ft.com/content/da70b2f9-3a0b-4258-9996-86dfd6802... contains a few interesting morsels of information -- including some touching on risk management & the risks that short sellers are exposed to in periods of market instability where there is a risk that counterparties might go bankrupt, e.g. during the GFC.
* "I've seen far more stocks go to zero than to infinity"
* "short selling is a portfolio [...] no one position will ever be more than 3 or 4% of the portfolio"
* "if you go into one of our partnerships, as a limited partner, you can only lose what you put in"
* "the short side has a lot of asymmetries: [...] if a position goes for you, it becomes smaller, unlike on the long side"
* "if you gave me $100 and I just had a one stock portfolio on the short side, you wouldn't have to give me any more money and if I shorted Enron $100 and continued to short it on the way down, I could make more than 100%. I'll let you think that through"
