to buy or sell ?-that is the questionI've been following this stock for a couple of years now. I had the good fortune of buying a mitt full at the very bottom recently. What to buy and when to buy are only two parts of the equation. The other part is knowing when to sell. Ordinarly I would take the money and run. To cut to the chase, yale has never traded over 7 million shares a day in its history. I think the share price is heading much higher.
