This happened once before when the stock first reached 20. It rose in the morning then fell sharply about four or five points, in the PM. There is one major shareholder who owns most of the stock leaving little float to be traded. I believe that NHTC is daytraded and once the trend turns, sellers unload in a big way. My advice is to let it settle for a day or so and once it starts to bottom and then move up, begin buying. The last time this happened the stock was quite volatile for about a week.
