Hi

I am looking to enter options trading and wish to have access to the international markets, I am currently also of the opinion that S&P 500 will fall over the coming months. I have noticed something I found odd lately, over the past 5 trading days the SPDR SPY fell for 4 days straight whilst the S&P 500 index and futures rose in the same timeframe. Could you give me your thoughts on this, is this an anomaly or is it an indicator of something? I thought the two were supposed to have a very high correlation.

Thanks
