In its compilations of the biggest up and down grade changes for the first three months of 2008, steady performances during the quarter helped lift TheStreet.com Ratings grades for a quintet of real estate mutual funds from the "D" range, which corresponds with a "sell" recommendation, to marks of "C" area, which equates with a "hold" advisory.

At the opposite end of the array of ratings changes as of the end of March, as can be seen in the accompanying table, were five funds that suffered double-digit percentage losses for the first three months of 2008.

With commercial real estate investment trusts holding their own thus far in the year, all but one of the real estate funds on the list rewarded their holders with positive investment returns during the difficult first quarter of the year. The

Oppenheimer Real Estate Fund

(OREAX) - Get Report

, held steady during the period.

The superior performance of the REIT funds for the latest three months followed weakness in 2007 that left the five funds deeply in the red for the latest 12 months.

The five funds with the steepest downward revisions in TheStreet.com Ratings scores generally held their own in 2007 before crumbling during the first quarter of this year. Except for the

Schneider Value Fund PPP

(SCMLX)

, their respective 12-month returns, while negative, are less severe than their year-to-date losses, meaning that all the damage has been in calendar 2008 to date.

The Schneider Value Fund is the only one of the list to descend from TheStreet.com Ratings "buy" territory to a grade that equates to a "sell" recommendation. It largest portfolio holdings include
