Index futures opened sluggishly following a three-day weekend. However, the economic calendar suggests the pace may pick up in the days ahead. T-bill auctions on Tuesday will give us a good read on demand at the short end of the yield curve, but the more important news will be the release of FOMC notes on Wednesday.  Existing home sales will be reported out that day as well, and it will be interesting to see whether the headlines support the strong recovery rally since the bombed-out low on Friday, February 9.
