  • 2013-03-23 23:56:41Dr. Tao, someone get a black box(statistic) model that been simply confirmed to fit different markets include single stock, stock market index and commodity present price by four years history. The expecting result is to get one order of magnitudes return by about four years. The actual return (partly instructed by the statistic model and partly by logic model) is to be per45 by 8 months(1206~1212with 30%, recent months with 15%). He is 35age, master degree, major for semiconductor physics and out of job.can you give some advices about risk ,job ,model etc to him? thanks a lot. By the way ,in finance history, some people claimed some models those later were actually tested to fail because of model itself or having been public.[回 复]
