Today was another significant down day on Wall Street. As we're approaching the British referendum about whether or not the UK should leave the EU, market participants are getting more nervous every day. The outcome of the referendum is not clear at all, and different polls predict different outcomes. Expect more volatility in approaching that referendum June 23rd. Also, this Wednesday is FOMC day which is somehow almost always reason for increased volatility. For trading the S&P 500 tomorrow, Tuesday, June 14th, the Greed and Fear indicator is expecting lower close.
