Citi's Keith Horowitz lowers Q2 EPS estimates for Goldman Sachs (GS) and Morgan Stanley (MS) as a tough June erases optimism from the start of the quarter. He sees Goldman reporting EPS of $2.70, down from $3.10 previously and against consensus of $2.83. Morgan is cut to $0.42 vs. consensus of $0.45. JPMorgan (JPM) might still surprise to the upside thanks to a boost from lower mortgage loss reserves. His $0.27 forecast for Bank of America (BAC) is ahead of the Street at $0.25, and Lazard (LAZ) at $0.33 is also modestly ahead of consensus.
