Are you concerned about 401(k) plan participants engaging in market timing and excessive trading?

I’m foolishly reading my statement, which includes the following:

Pursuant to new SEC rules, fund companies are required to enter into agreements with intermediaries to provide fund companies with the ability to identify and enforce restrictions on Participants engaged in market timing or excessive trading (prohibited trading), as defined by fund companies.

[Participants may be warned or restricted immediately.]

Thank you, SEC, for protecting me from the middle class.
