Investors hope the lower gasoline cost is putting more money in consumers' wallets for spending on apparel and other retail goods. The next two weeks will indicate whether that's happening. The coming weeks, as the fourth-quarter earnings season gets underway, are among the more active periods of the year for retailers to issue earnings preannouncements. The fourth quarter includes the crucial holiday shopping season.
An industry conference, the ICR Xchange in Orlando, Florida, which starts on Monday, is a particular area of focus.
Analysts expect companies presenting at the conference - which include Lululemon Athletica, Big Lots and Guess - to shine a light on holiday trends and discuss business expectations for 2015, and in some cases update their outlooks.
The early indications have been supportive, with a number of retailers reporting strong December sales this week. J.C. Penney Co, American Eagle Outfitters and Aeropostale Inc all had strong results, though Macy's disappointed.
The flood of market commentary from next week's conference will likely provide more colour on the sector's prospects. Despite its solid sales, J.C. Penney announced store closures, while struggling apparel retailer Wet Seal Inc said this week that it laid off 3,700 workers, so clearly there are divergences in the fortunes of retailing companies.
"People are betting on volatility for sure. Money is moving in - they're betting on moves," said Dennis Dick, head of markets structure at Bright Trading LLC in Las Vegas. "If you're chasing these, there's going to be a lot more risk."
The 30-day at-the-money implied volatility for the SPDR S&P retail exchange-traded fund, a gauge of the risk of large moves in the ETF, is at 19 percent, or higher than 90 percent of readings in the last 52 weeks, according to data from options analytics firm Trade Alert.
Despite the early upbeat results, investors are wondering if the stocks have become overvalued.
The sector "feels like it's a bit stretched," said Chris Bouffard, chief investment officer at the Mutual Fund Store in Kansas City, Missouri. "I'm having a hard time assessing whether the mainstream consumer really believes gas prices are going to be a sustained savings for them."
The broader Consumer Discretionary Select SPDR fund has seen inflows of $278.87 million so far this year, according to data from ETF.com, while the SPDR S&P Retail sector ETF, which closed at a record on Thursday, has seen outflows of $41.09 million.
With the retail ETF close to its all-time high of $97.15, some are looking to the options market for protection against losses.
Over the last few days there has been increased buying of puts on the XRT at the $95 strike expiring in January, and similar activity was seen in puts on several retailers, J.J. Kinahan, chief market strategist at retail brokerage TD Ameritrade Holding Corp, said.
"They don't necessarily want to get rid of the shares, as there is optimism around earnings, but want to protect themselves," he said.
