吹吹aapl吧!
Aapl trading at 268ish....now
上两个星期当它还在250时,260-270, 270-280 call是非常active, even higher option strike was very active.
看看今天260-270call is most traded, but not 270-280call, no higher strike being traded. 怎么会事? 经过几天的小回调,却没有人buy dip. 看来aapl hit a speed bump.
By the way, 260-270 call is a gamble bet, trader with a max risk of $5.xx to gain max reward of $4.xx. 这样的risk/reward ratio 值吗? |
