Ok first off, I admit I know nothing about stocks, so excuse the probably common knowledge questions... Anyways, I heard on the radio today about "Total Stock Market Investment" or something like that.. Has anyone heard of that or something like that? The way they described it, it was basically like buying into the entire american economy, not a specific company or somethin'.. Anyways, I heard it on the Clark Howard show and it got me curious, cause I mean, I dont have a bunch of spare cash right now, but I feel as the stock market being as low as it is right now, I'm 100% positive it's going to come back eventually (or else I got bigger problems than losing the money I want to invest lol).

Anyways, cliff notes.
1. Has anyone heard of anything like "total stock market investment" or something similar? If so, can you give me some basic info on it or point me to a good site for it?

2. Whats a good online trader for a newbie?

Thanks much.
