Homebuilders D R Horton (DHI) - Get Report , KBHome (KBH) - Get Report , Lennar (LEN) - Get Report , Pulte Group (PHM) - Get Report and Toll Brothers (TOL) - Get Report have mixed weekly chart profiles in the wake of a rise in homebuilder sentiment and slight rise in single-family housing starts. These stocks can be traded but not owned because of the share price volatility shown in today's charts. Let's take a look.

Lennar reported quarterly results before the opening bell on Tuesday and beat analysts earnings-per-share estimates. The stock popped by 4.9% to a high of $48.95 in pre-market trading.

KB Home reports their quarterly results after the closing bell on Tuesday and analysts expect the company to earn 16 cents a share.

The National Association of Home Builders Housing Market Index rose two points to a reading of 60 in June as builders report higher traffic from committed new home buyers. Homebuilders continue to be concerned about a shortage of building lots and labor, and indicate that there is softness in some markets around the country.

Single-family housing starts are up nearly 10% year over year but inched up just 0.3% in May to a seasonally-adjusted rate of 764,000 units, still well below potential.
