| Finally a question I can answer (but ppl might not like it)! :) It’s my personal opinion, based on my time and experience (and several books about the field), “90% fail” in the same way “90% of business fail.” Tons of reasons but I truly believe lack of alpha is overestimated. I think finding alpha is not nearly as hard as people make it out to be. Execution and continuously innovating is the real challenge. Design your systems, knowing you will have to change up your strategy and focus on a system that will help you find new alpha. I believe after lots of research, this is how Rentech did it. And to touch on the business ananology again, you could have the best donuts in town but if the rest of your business is fundamentally flawed, it will become part of the “90%.” Now, I’ll say this, I don’t manage some insane portfolio or anything. However, I run a private firm (myself and family) that makes for a comfortable life. I work more than 9-5, but I enjoy the challenges and freedom. If you’re asking about more complex bots used in managing larger, institutional funds, I’m afraid I can’t answer that… but I imagine the challenges are quite different. I try to post things that have helped me with building these systems from time to time. http://www.twitter.com/robswc Lmk if there’s anything else, I can try my best to answer. |
