DYII shares dropped steeply after the firm's 3Q 2008 net income fell to $1 million from $2.6 million in 2007 despite a 13% increase in revenues from the same period. The drop was attributed to jumps in compensation and medical supplies expenses, which increased along with the number of patient cases. The company also announced that it had sold its interest in a joint venture which was to construct a hospital in Shanghai, China, further disappointing investors.
