Trader Brian Jones on Twitter: "Well the s&p did fall 100+ but now crash today. Why not? I'm going today. 1) Because it tested the bottom. 2) Hasn't had a rally in a while and got an oversold bounce. 3) Lastly, I think it's because Crashes come in October." / Twitter

Well the s&p did fall 100+ but now crash today. Why not? I'm going today. 1) Because it tested the bottom. 2) Hasn't had a rally in a while and got an oversold bounce. 3) Lastly, I think it's because Crashes come in October.
