(Adds clarification on proposed fees in penultimate paragraph.)

Direxion Funds, the Newton, Mass.-based ETF firm known for its leveraged and inverse funds, put another four funds into registration focused on the Dow Jones industrial average—one bull-and-bear double-exposure pair, and another bull-and-bear pair of triple-exposure funds.

The company already put a single-exposure Dow 30 fund into registration as part of a 24-fund mega filing with the Securities and Exchange Commission in December 2010.

The new funds it described in the regulatory paperwork included:

• Direxion Daily Dow 30 Bull 2X Shares
• Direxion Daily Dow 30 Bear 2X Shares
• Direxion Daily Dow 30 Bull 3X Shares
• Direxion Daily Dow 30 Bear 3X Shares

Additionally, the company also put two triple-exposure European-focused equity funds into registration. Those are:

• Direxion Daily European Equity Bull 3X Shares
• Direxion Daily European Equity Bear 3X Shares

The proposed funds will each have an annual management fee of 0.75 percent, though that is not an all-in annual expense ratio. The firm has historically priced its funds in line with products offered by ProShares, which often come with annual expense ratios of 0.95 percent.

Leveraged and inverse funds like those sponsored by Direxion and ProShares are designed for traders and other experienced investors. They rebalance daily, meaning their returns often deviate from their underlying indexes, particularly in trendless and volatile markets.
