On Tuesday's MarketFoolery, host Chris Hill and Motley Fool Funds analyst Bill Mann answer an email about the National Oilwell Varco (NYSE:NOV) spinoff. The email asks, "Could you guys please talk about how one should handle the new DNOW investment I'm not part of?"

Chris says the surprising part is that National Oilwell Varco CEO Pete Miller will be moving with the spinoff. Bill, meanwhile, doesn't think investors need to worry about the stock price over the short term, because of institutional shareholders that have certain mandates. Bill dives into what investors should take away from Miller's move with the spinoff, and Chris agrees, but he also considers the homework for investors and the reasons to hold or to not hold on to the spinoff stocks.
