Dropbox has filed to conduct an IPO. It will trade under the symbol DBX. Underwriters include GS, JPM, BAC and DB.
Often our subscribers who are high net worth private investors, hedge funds, institutions and other money managers are able to get shares. If you have a small account with an online broker, you are not likely to get the shares.
Underwriters often price these shares so that there is a nice gain in the post IPO market. Consider getting up to 100% of full core position size. Often you will have to put an order for much higher number of shares as you are likely to get only a fraction of the shares you request.
