Interesting -- when you go to http://www.mffais.com/panl.html to look at fund holdings, you get the following pop-up: "Universal Display stock (PANL) was recently dumped by 19 funds." They could just as easily have said that PANL holdings were recently increased by some 50 funds! The site MFFAIS - Mutual Fund Facts About Individual Stocks - obviously has a not-so-hidden agenda.
If you go to MAFF copy and paste it into a spreadsheet and add up the changes you are left as -11,706 shares since the start of Febuary (an arbitrary date - choose your own as you wish)
However, you may notice that two of the big sellers, Vanguard(500,000) and Credit Suisse (165,000) are actually liquidating their assets - click through on their names and you will see there's a fire sale going on.
Remove them from the equation and you have 672,000 shares bought by funds. Assuming a float of 36million shares that's +1.9%.
