Home Depot has been running higher as the housing market heats up, and traders are looking for even more gains.
OptionMonster's trade scanners detected heavy volume in the January calls, with the 67.50s trading for $0.91 and the 70s fetching $0.33. The trader may have been selling the lower-strike calls and buying new ones at the higher level.
Calls lock in the price where a stock can be bought, so they can generate some nice leverage in a rally. Winning positions in one contract can also be rolled into new calls, letting investors take profits while remaining exposed to further gains.
Home Depot shares fell 0.14 percent to $64.98 yesterday. The home-improvement retailer's shares have soared more than 50 percent this year and are now back to levels not seen since early 2000.
Calls outnumbered puts by about 23,000 to 7,500 in the session, which shows how bullish sentiment was yesterday.
