Retail REITs as a group posted total returns of 33.41 percent in 2010, according to NAREIT—the second straight year that the sector delivered strong results.

The figure for all retail REITs made it the strongest year since 2004, when retail REITs posted total returns of 40.23 percent. The total return index at the end of the year stood at 584.29 and is up 169 percent since bottoming out at 216.82 in February 2009. However, the index remains 33 percent below its all-time peak of 878.58 reached in April 2007.

By sub-sector, freestanding retail REITs led the pack with total returns rising 37.37 percent in 2010 followed by regional mall REITs (34.64 percent) and shopping center REITs (30.78 percent.)

Overall, NAREIT reported that U.S. REITs continued to significantly outperform the broader equity market in 2010. The FTSE NAREIT All Equity REITs Index delivered a total return of 27.95 percent in 2010 and the FTSE NAREIT All REITs Index gained 27.58 percent compared to 15.06 percent for the S&P 500. REITs’ 2010 returns came on top of 2009 gains of 27.99 percent for the FTSE NAREIT All Equity REITs Index and 27.45 percent for the FTSE NAREIT All REITs Index.

According to NAREIT, at year-end 2010, the equity market capitalization of the U.S REIT industry had increased to $389 billion, up 44 percent from $271 billion at the end of 2009, but still trailing that of the peak year of 2006, when equity market capitalization reached $438 billion at year-end. The retail sector accounted for $96.2 billion of that total.

All sectors of the U.S. REIT market delivered positive returns in 2010, and all but two sectors produced strong, double-digit returns. Top performing industry segments for the year were apartments, up 47.04 percent; lodging/resorts, up 42.77 percent; and commercial mortgage financing, up 41.99 percent. Industrial REITs were up 18.89 percent and office REITs were up 18.41 percent.

In addition, 2010 marked the second biggest capital raising year ever for REITs, trailing only 2006. Overall, U.S. REITs conducted 173 offerings and raised $47.45 billion. That was up from 130 offerings for $34.66 billion in 2009 and 82 offerings for $17.99 billion in 2008. In 2006, REITs conducted 204 offerings that raised $49.02 billion.

By type, REITs completed nine IPOS that raised $1.98 billion, 91 secondary offerings of common shares that raised $23.63 billion, 17 secondary offerings of preferred shares that raised $2.62 billion and 56 offerings of unsecured debt that raised $19.23 billion.

“In a commercial real estate marketplace in which many private owners have continued to find it difficult to raise capital to restructure highly leveraged balance sheets, REITs again demonstrated their cost-effective access to capital through the public markets,” NAREIT President and CEO Steven A. Wechsler said in a statement.

According to NAREIT, REITs have largely used the capital raised to pay down debt and begin to make strategic acquisitions. The industry’s debt ratio as of September 30, 2010, was 41.4 percent, down from 66.3 percent at the end of February 2009.
