Today's Volume: 1,690,000 Average Volume: 1,146,380 Volume % Change: 283% This stock is exploding to the upside today after the company beat its third quarter forecast, and said they will remain on track for $1 billion in sales. Mentor posted earnings of $24.1 million, or 22 cents per share, versus earnings of $15.2 million, or 14 cents per share a year ago. From a technical standpoint, this stock has started to break out above some past overhead resistance at $12 to $12.08 on high-volume. Market players should now look to buy the next big breakout that will trigger once this stock moves above its 200-day moving average of $12.54 and then above some more overhead resistance at $13.08. A sustained high-volume move and close above those levels sets this stock up to trade back towards $14 to $16.50 a share. I also featured Mentor in " 5 Earnings Stocks Poised to Pop."
