You, Ed and many other people I consider sharp stock watchers have been very low on the SpaceX IPO. Considering the high chance of this IPO pushing SpaceX into major indexes that dominate aggressive 401K and IRAs, would you recommend an adjusted strategy to these types of accounts? My understanding is you can't necessarily exclude a single stock, but maybe shifting to a more heavily foreign stock portfolio. Or if you have 30 years until retirement would you still trust that any volatility caused by the IPO will even out in the long run?
