arrayList <E>

If this has been asked and answered I apologize. I tried searching for an answer and couldn't locate one. I am updating an old application switching from vector to arrayList. Much cleaner code. I now get the following warnings and can't figure out how to correct them. I used the -Xlint parm to get the details:

PortfolioManager.java:74: warning: [unchecked] unchecked call to add(E) as a member of the raw type java.util.List

arrayListPortfolios.add(portfolio);

I know I need to add something to the code, but I can't figure out what it should be. TIA
