<p> March 20 (Bloomberg) -- The U.S. stock market is the most <a onmouseover="return escape( popwQuoteShort( this, 'SPX:IND' ))" href="http://www.bloomberg.com/apps/quote?ticker=SPX%3AIND">volatile</a> in 70 years, according to a Standard & Poor's study of daily price swings in the S&P 500. </p>
<p>The benchmark for American equities has <a onmouseover="return escape( popwQuoteShort( this, 'SPX:IND' ))" href="http://www.bloomberg.com/apps/quote?ticker=SPX%3AIND">advanced or declined</a> 1 percent or more on 28 days this year. That's 52 percent of the trading sessions so far, which is the highest proportion since 1938, said <a onmouseover="return escape( popwSearchNews( this ))" href="http://search.bloomberg.com/search?q=Howard+Silverblatt&site=wnews&client=wnews&proxystylesheet=wnews&output=xml_no_dtd&ie=UTF-8&oe=UTF-8&filter=p&getfields=wnnis&sort=date
:S:d1">Howard Silverblatt</a>, S&P's senior index analyst. The S&P 500 lost 12 percent in 2008 through yesterday following $195 billion in bank losses related to subprime mortgages. </p>
<p>``The enormous uncertainty of the market is translating into volatility,'' New York-based Silverblatt said in an interview. ``Everyone is reacting to the day-to-day events as opposed to the longer-term trends.'' </p>
<p>In 1938, the most volatile year since the index's inception in 1928, the S&P 500 rose or fell at least 1 percent during 57 percent of the trading days, according to Silverblatt's analysis. The measure advanced 25 percent that year. </p>
<p>Option prices, which increase when investors expect wider share-price swings, have risen this year. The <a onmouseover="return escape( popwQuoteShort( this, 'VIX:IND' ))" href="http://www.bloomberg.com/apps/quote?ticker=VIX%3AIND">Chicago Board Options Exchange Volatility Index</a>, the price gauge for contracts linked to the S&P 500, has averaged 26.15. That's 49 percent higher than the level in 2007. The so-called VIX closed at a five-year high of 32.24 on March 17. </p>
<p>In 2002, when U.S. stocks hit bottom after collapsing in March 2000, 1 percent moves in the S&P 500 occurred 50 percent of the time, Silverblatt said. That fell to 12 percent in 2006 and 13 percent during the first half of last year. The figure increased to 39 percent during the second half of 2007. </p>
<p>``The upcoming earnings season appears poised to add to the volatility,'' Silverblatt wrote in a report yesterday. Profit ``estimates are unusually wide, given how close to the quarter end we are.'' </p>
<p>The first quarter concludes in less than two weeks. Alcoa Inc. is scheduled to become the first member of the Dow Jones Industrial Average to report results for the period on April 7. </p>
