James O'Shaughnessy on a lot of things
Back in May, an investor named James O'Shaughnessy, author of a superb book What Works on Wall Street, blessed the Twitterverse with a storm of insight I've aggregated below.
I'm a huge fanboy of Jim's and a client of his firm. What I love about this set of tweets is the honesty required to lay out, in no uncertain terms, what he does not know.
I hope my doctor, my attorney, my CPA, and every professional service I use can approach their work with this level of humility.
Also, markets are hard.
