among investors? >> today is a 400 point range for the dow. the s&p 500 is down 6% from its record highs, it hasn't officially done a correction and closed in correction territory which means you could see some more toing and froing as you get to that. there's a lot of computer activity here. one of the veteran traders we talked to, market analysts we talked to, on a typical day, 50 to 60 algorithms and computers are saying, the stock program will sell that. 90% yesterday. real people were frustrated because mom and pop investors were in there trying to sell stocks in the online trading platforms and couldn't. by the end of the day it completely turned around. it's been a little frustrating for the average investor and i would really encourage everyone to look at the percentage moves.
