It isn't too often I sit and watch a stock, but watching this thing go up and down between the low 91.xx and up to 92.xx, got me thinking.
If one had the time and money to trade a large number of shares on something like this, you could make a killing in a days time - of course you'd be taxed like crazy, but could still come out ahead if you were volume trading a stock for roughly $1 more than you paid per share to buy. At least on BABA today you could've done that a few times, buying on the lows and selling on the highs.
Not a new idea and high risk, but it could've been done on this one today if played right...
