ADP is typically regarded as unreliable, it'll be interesting to see what Friday brings.
The ADP report was off by about 80,000 in January (showing fewer than BLS) and March (coming in more than BLS):
The number of jobs added was the fewest ADP has reported in seven months. Stock futures fell after the report was released.
The survey, which covers hiring only in the private sector, has been known to deviate sharply from the government's figures, which wil, be released Friday. For example, the government said employers added just 120,000 jobs in March — much lower than ADP's estimate.
