i'm donna rosato. >> tom: just a reminder, you catch us online at n.b.r. on www.pbs.org. there you can comment on our blog or watch any programs that you may have missed. or you can follow us on twitter at "biz report" or my personal feed at hudson n.b.r. if tweeting isn't your thing, friend us on facebook at "biz report." finally, if you watched monday night's program, you know we had a guest on who said that historically the first trading day of the month is usually a good time to invest. rick bensignor attributed that trend to people investing their paychecks at the beginning of the month, but that certainly wasn't the case yesterday. so, what happened? bensignor says the market zigged when so many were looking for it to zag. in essence, he blames yesterday's 168-point drop on the spike in oil prices. next month, the first trading day is friday, april 1, so, susie, we'll see if the markets get tricked on april fool's day. >> susan: only if you're superstitious. >> tom: that's "nightly business report" for wednesday, march 2. i'm tom hudson. good night, everyone. and go
