Just a reminder
US stock option is expired on the Saturday following the third Friday,
i.e. Apr 16, 2011. A wild guess is that they will support the US markets
until end of this week because of the option expiration.
Also, US funds seem to leave the US market and back to other lag behind
market, say "Hong Kong"
So beware if there is a correction these weeks
,
(step down and collect), then sharp rebound afterward
.
