Does anyone have logistical issues or concerns they know of from protocols of flopping over from a PHLX to an NASD firm -- such as securities licenses issues?? For example, there are specific licenses you can only obtain by working with an NASD firm. IF you start out with a PHLX firm, most will only get you the 7. Does this turn out to be a big headache at some other point in time if you make a career change in firms???? One other consideration, does this say anything about a firm that only has membership with the PHLX and not NASD or an SIPC plan??
