<prompt> Human: This is a snapshot of my portfolio. My entire portfolio shot down 8 between the 28th and the 29th. Im not super stock savvy so just curious what happened. to the market that day.  <response>: One word - GreeceThe market has been dropping and rising a bit every time there is good or bad news related to Greece. Sunday they effectively said they have no intention of attempting to repay their debts so the market dropped. International would have taken a big hit.The fact that you lost 8 is concerning, the US market lost 2 on average, some sectors got hit a bit harder but not 8 hard. You should figure out which of those funds took the big hit and try to understand why, and if you can afford to be in that one.
