NEW YORK ( TheStreet) -- An advisory committee tasked with helping regulators address the issues raised by the May 6 "flash crash" weighed in Friday with a report listing 14 recommendations for changing how stocks are traded.

The "flash crash" refers to a sudden drastic drop in the stock market that resulted in the Dow Jones Industrial Average losing some 900 points in a matter of minutes, before quickly recovering. Many of the most extremely divergent trades made during that period had to be voided, though many other investors saw massive gains or losses.

The panel identified high frequency trading as a major reason for the crash, a key part of what it calls "the new dynamics of the electronic markets" for equities and exchange-traded derivatives. The panel acknowledges that such changes have boosted competition and made trading cheaper for market participants, but warns that "they have also created market structure fragility in highly volatile periods."

Among the recommendations the panel makes to the Securities and Exchange Commission to enhance rules it made in the wake of the flash crash.

Among other things those rules created circuit breakers for Russell 1000 stocks and actively traded exchanged traded funds. The rules also put in place increased responsibilities for market makers, such as eliminating their ability to offer "stub quotes"--orders at absurd prices that are meant as "placeholders" but are not meant to be executed.

Such stub quotes are seen as one of the factors contributing to the flash crash.

Kevin McPartland, a senior analyst with capital markets advisory firm TABB Group, has some concerns about the panel's approach.

"They want to ban a lot of practices. If they ban a practice, the market will likely find another way to do what they need to do. It would make much more sense to try to create a market structure that incents certain behavior," he says.

However the market reforms shake out, they are expected to benefit companies that provide technology to trading firms, such as Sybase, which was acquired last year by German technology giant SAP ( SAP), in a deal announced just six days after the flash crash. U.S. listed shares of SAP are up more than 30% since the flash crash, compared to a less than 18% rise for the Nasdaq.
