Wal-Mart's warning just shook these two IPOs

Albertsons & First Data IPOs struggling

Two IPOs who were looking to price on Wednesday after the closing bell may have been seriously spooked by Wal-Mart's market-shaking move earlier in the day.

Just barely into the trading session on Wednesday, the retail giant announced that its full-year sales would be flat in 2016. That sent stock tumbling into its worst trading day in more than 25 years on a percentage basis.

Two companies set to go public, Albertsons and First Data, both took a hit as a result of the market's Wal-Mart jitters.

Wal-Mart just raised the stakes for everybody else

First Data, a payment-processing company, priced Wednesday night at $16, below its target of an $18 to $20 range.

Supermarket operator Albertsons was shooting for a range of $23 to $26, but reports surfaced Wednesday that the company might price closer to $20 or less. The company moved its pricing to Thursday.

Wal-Mart's lowered guidance weighed heavily on the Dow Jones industrial average and raised questions as to whether U.S. consumers are seriously tightening their wallets.
