It's been a tough year for commodities.
Gold, crude oil and natural gas are down a respective 6, 11 and 21 percent in 2015. Those returns have caused the S&P GSCI commodity index to hit its lowest level since the financial crisis. It's also on track for its fourth worst year on record, but according to one expert, there could be signs of a bottom.
"The ugliest month [of the year] was in July where every single commodity was negative except one," Jodie Gunzberg told CNBC's "Futures Now" on Tuesday. "But we had a major comeback in October; where more than half became positive on the month, and we've never seen that kind of swing before when so many commodities were down."

Gunzberg, global head of commodities at S&P Dow Jones Indices, noted there were two other instances in the S&P GSCI commodity index where a sharp rebound resulted in a short-term bottom for commodities. "In January 2009, 11 single commodities came back just before the S&P GSCI hit its bottom," she said. Gunzberg noted there was a similar pattern in 1998, where the space staged an incredible comeback off the low.
