best stocks to buy with Markets down

Any advice on which stocks would be wise to buy now while they are at a discount? The cruiseline stocks are way down and I'm thinking about buying into Carnival or Royal C.

What is your holding period ?  i.e. is this a trade or an investment ?  Any stocks involving mass groups of people (airlines, gaming, cruise operators) are likely most at risk over the next 12 months.  No need to go dumpster diving IMHO in these areas.  Pick something else,  maybe tech (GOOGL, MSFT, FB).   IMHO, stay away from AAPL.  This company IMHO is going to be challenged in a post China Virus World , with ALMOST ALL of their production in China.  That is not good.  The other three I mentioned are more cloud/software/'digital advertising' based,  and do not have that problem.. 

 If this is an investment longer terms , why not just buy the whole market (SPY). 

Way too early for Cruise Lines. Agreed. Whatever you do I would wait for a down tick or three. It's coming.
