Energy stocks just notched their second-best trading day of the year.
The S&P energy sector rallied 3 percent Tuesday as crude oil snapped its five-day losing streak and bounced off a four-month low. And according to one top technician, the rally is just getting started.
"We came into [this rally] extremely oversold, about the most oversold we've seen since early April," Jonathan Krinsky said Tuesday on CNBC's "Futures Now." The energy sector is currently in the midst of a 12-week losing streak, which by Krinsky's work is the worst in its plus-25-year history.
