If it's short term gains, I think yes it will bump you into the next bracket. It's taxed at the same rate as your regular income.

A long term investment gain is separate from the regular income. You look at your tax bracket based only on the regular income in order to determine the tax rate for your long term gain (which doesn't get added to regular income, it stays separate and gets the lower rate).
