| Highlights    Last week, U.S. stocks suffered their worst drop in over nine  months as a terrorist attack and poor economic and earnings data  shook investor confidence.  Breaking down last week's market drivers may reveal insights  about the likely future direction of the stock market. Is Investor Complacency Finally Ending?Last week, U.S. stocks suffered their worst drop  since June 1, 2012, measured by a 2.1% loss-totaling 318 points-in  the Dow Jones Industrial Average. The week began with a terrorist  attack that disrupted the Boston Marathon and a report that China's  economic growth unexpectedly slowed in the first quarter of 2013.  Throughout the week, first quarter 2013 earnings results, including  widely watched companies such as Bank of America and IBM, missed  analysts' expectations. The U.S. stock market has risen for much of this  year, despite the United States' fiscal failings, another European  bailout, geopolitical threats, high energy prices, and weak global  economic and earnings growth. So last week's notable drop may mark  a departure. Breaking down last week's market drivers may reveal  insights about the likely future direction of the stock market. Terrorist Attacks A major terrorist attack that disrupts economic  activity and raises security fears is always a risk for the capital  markets-especially considering that terrorist attacks of all types  around the world now total over 4,000 per year, according to data  compiled by the Institute for Economics and Peace. The human toll is immeasurable. The impact of  the terrorist attacks will stay in the hearts and minds of  Americans long after any economic cost is recouped. With many  thousands of terrorist attacks worldwide over the past 25 years, we  have a lot of history to examine when looking at the economic or  market impact of an attack. Historically, major acts of terrorism have not  had lasting long-term negative effects on financial markets. In the  countries where these attacks have occurred, the stock market has  fully recovered in one week, on average (excluding the 1990 London  Stock Exchange bombing, when an unrelated recession emerged around  the same time). 
 With the exception of the 9/11 attacks on the  United States, there has never been a terrorist attack that has  materially and negatively affected economic activity. The 9/11  attacks depressed economic activity for a very short period;  however, the fourth quarter of 2001 marked the end of the  recession, when economic activity re-accelerated from the  third-quarter loss of 1.1% in real gross domestic product (GDP)  with a fourth-quarter gain of 1.4%, followed by a 3.5% gain in the  first quarter of 2002. The stock market responded similarly; within  a week of reopening after the 9/11 attacks, the stock market was  rallying-in the following nine weeks, the S&P 500 posted a gain  of 20%. Nevertheless, there is still the risk that, for  the first time in history, a terrorist attack would result in a  serious disruption of economic activity and cause substantial  declines in the markets. If the attack remains a tragic-but  isolated-event, it is unlikely to alter the market's direction.  However, a series of follow-on attacks-the letters laced with the  poisonous toxin ricin sent to the President and a U.S. Senator last  week, for example-may erode confidence and negatively impact  consumer spending, business investment, and investors' willingness  to buy stocks, sending the market lower. Data Sensitivity In the past, stocks have had more significant  reactions to changing economic fundamentals and geopolitical events  rather than terror attacks. An example can be seen in the lengthy  stock market decline that followed, but was unrelated to, the  London Stock Exchange Bombing in 1990. The London Stock Exchange  Bombing was followed two weeks later (August 2, 1990) by Iraq's  invasion of Kuwait, and July 1990 marked the start of a recession  in the United States. What may be more important to market direction  in the coming weeks is the increasing sensitivity of the stock  market to disappointing data, as evidenced by thereaction on  Monday, April 15, 2013 to China's GDP report. This resulted in a  1.8% stock market decline, which was driven primarily by  disappointment in the report on first quarter economic growth in  China that was released before the market opened and led to a  decline that unfolded steadily throughout the day. Most of the  decline had taken place by the time of the Boston Marathon terror  attack at 2:50pm ET. Economic data are increasingly falling short of  expectations. The Citigroup Economic Surprise Index measures how  economic data for the world's major economies fares compared with  economists' expectations. In recent years, a slide in this index  has corresponded to a slide in the performance of stocks relative  to bonds. The index has peaked and made a steady decline in recent  weeks, but only now may the stock market be beginning to react. 
 Disappointments came from companies, as well.  While many companies are able to meet or beat the very low earnings  growth expectations of about 1-2% for the first quarter of 2013  from a year ago, revenues have been weak. Of the 91 S&P 500  companies that reported revenues, more than half (56%) missed  expectations, according to data tracked by Thomson Reuters. Market participants may be getting increasingly  sensitive to disappointing news after being complacent for some  time. The VIX, the market's so-called "fear" gauge, jumped up and  averaged 16 during the past week, after averaging a complacent 13.6  this year. While 16 is a far cry from the levels north of 25 seen  during last spring's 10% stock market slide or even the 22 reached  during November 2012's 7% pullback in the S&P 500, it is a sign  investors are becoming increasingly wary of news or events that  could prompt another decline.         IMPORTANT DISCLOSURES The opinions voiced in this material are for  general information only and are not intended to provide specific  advice or recommendations for any individual.

Dow Jones Industrial Average (DJIA): The Dow  Jones Industrial Average Index is comprised of U.S.-listed stocks  of companies that produce other (non-transportation and  non-utility) goods and services. The Dow Jones Industrial Averages  are maintained by editors of The Wall Street Journal. While the  stock selection process is somewhat subjective, a stock typically  is added only if the company has an excellent reputation,  demonstrates sustained growth, is of interest to a large number of  investors and accurately represents the market sectors covered by  the average. The Dow Jones averages are unique in that they are  price weighted; therefore their component weightings are affected  only by changes in the stocks' prices. The Standard & Poor's 500 Index is a  capitalization-weighted index of 500 stocks designed to measure  performance of the broad domestic economy through changes in the  aggregate market value of 500 stocks representing all major  industries. The VIX is a measure of the volatility  implied in the prices of options contracts for the S&P 500. It  is a market-based estimate of future volatility. When sentiment  reaches one extreme or the other, the market typically reverses  course. While this is not necessarily predictive it does measure  the current degree of fear present in the stock market. This research material has been prepared by  LPL Financial.
