Not too many people. The trades you see are the MMs trading it back and forth, the same shares over and over. Yet who ever is accumulating realizes that they have to ultimately raise the bids to accumulate any shares in any significance. Most people can read a chart that an increase in volume and price means, the stock is going one direction. Few are selling and watching this play out, especially with all the fundamentals that support this.
That doesnt mean that the shorts wont drop the price suddenly, especially in a weak market. The trend is your friend as they say.
