"Sun Healthcare Group (NASDAQ : SUNH) is a small-cap, California-based, healthcare facility company that specializes in inpatient, rehabilitation, and medical staffing services.

"SUNH has 24,000 beds and 213 long-term care facilities in 25 states; 416 rehabilitation centers in 33 states and temporary medical staffing in 38 states.

"The 'best' investors have increased their holdings in the stock by 38%, while the 'rest' have decreased their positions by 1%. The Best Investors began purchasing SUNH in January 2005 at $8 and they would gradually increase those shares until selling some in July '06 at $8.

"Later, in January 2007, a significant purchase was made at $12, and many of those were then sold in May 20'08 at $14. Now, in the past two weeks, the Best Investors have purchased more shares of Sun Healthcare.
