you say hey cramer, what do you think of that xyz corp. i say what do you think? tell me what it does? tell me why you bought it? the vast majority of the time people don't know either answer. they don't know either answer. they got a tip or saw a chart or heard from some uninformed chart. but they have no idea what it does or how it's even doing. they don't know in a lot of cases what it makes. how it makes it's money. they don't know if it pays a dividend or know if it makes money or loses money. they have no idea. by the way i see this all the time too, jim cramer on twitter, should i buy more, should i cut my losses. i say why did you buy it in the first place and if you don't know of course you should sell. here's what you need to do. ask yourself the same questions i put to the perfect strangers every day. can you answer them? do you know them? if not, you shouldn't be investing in that stock. maybe you shouldn't be investing in any stock until you do. there's always index funds and good mutual funds. the first rule is get knowledge, please. know what you ow
