The "Fast Money" traders debated what securities are worth holding in an environment with little to no yield, after the yield U.S. 30-Year Treasury bond hit its lowest level since Feb. 12.

Trader Guy Adami said that he believes that securities that have rallied will continue to go up. He said that things like the SPDR Gold Trust and iShares 20+ Year Treasury Bond ETF, also known as the TLT, are "still a buy."

Trader Brian Kelly said he also bought into the TLT on Wednesday on the back of a very strong bond auction earlier in the day. Kelly said he also agrees with Adami on gold. He said he also bought gold and silver, like the iShares Silver Trust.

"If we have that inflationary type of scale or increase, gold and silver will do well," Kelly said.

Trader Karen Finerman said she doesn't agree on buying gold ahead of a potential interest rate hike from the Federal Reserve.

"To me, if the Fed is raising, I don't see that as necessarily bullish for gold," she said, adding that the CBOE Market Volatility Index is a better, cheaper option.

Trader Tim Seymour said the emerging markets securities like the iShares MSCI Emerging Markets ETF are doing well and could continue to do so. He said 35.20 is the "level to watch" on the EEM.

"Emerging markets have had the biggest move since Yellen, since the payroll number. ... It looks like emerging could really explode," he said.
