heard on cnbc that there was some large insider selling from yahoo to geo cities. The big boys buy at the start of the run and sell off at the top. They are now taking their profits and going on to the next stock of choice. The big boys have information that you dont but you can still sell at this point and buy it back at the 160-170. Or, just hold and watch your value go down and then back up on the next run. It all depends on your choice of how to invest. Either way, you will make money with yahoo but the invester that knows this stock and plays its trends will make substanially more money which buys more yahoo stock.
this is the art of shorting, those thought 181-182 is a good buy will cut their lost when YHOO drops down to 179. those who got in at 188 and above will hold and hold for long time. go ahead buy YHOO now then sell it at a lost later!
It is cute to watch how the price can jump $1-$2 in a minute, just to get some of the ignorant ones thinking we have a rally going, when in reality the MM's just want to sell some of the cheap stock they accumulated a minute or two earlier, and then the selloff can continue in earnest again.
