NEW YORK ( TheStreet) -- On June 19 TheStreet will cover a quadruple witching day in the options and futures markets, notable earnings and key economic data.

The market may see extra volatility as all four asset classes, stock index futures, stock index options, stock options and single stock futures, expire on the same day.

Futures and options investors must close out of their positions.

Trading volume will likely be higher than normal.

On the earnings front, we note quarterly earnings reports from used car company CarMax  (KMX) and homebuilding company KB Home (KBH).

Both companies are scheduled to report before the market opens.

CarMax, the biggest used-car retailer in the country will post its first-quarter earnings.

CarMax is expected to earn $.86 a share on revenue of $4.157 billion, according to analysts surveyed by Thomson Reuters.

In the same quarter of last year, the company reported a profit of $.76 a share on sales of $3.75 billion.

Richmond, Va.-based CarMax is a holding company, providing used vehicles and related products and services.

The CarMax sells used vehicles and related products and services, purchases used vehicles and arranges automobile financing options.

The company's finance operation provides vehicle financing through CarMax stores.

CarMax operates roughly 131 used car superstores in 64 metropolitan markets.

TheStreet also notes one report on the economic calendar. The Atlanta Fed's Business Inflation Expectations survey will be released. The survey gives a monthly measure of inflation estimates from the perspective of firms.

The inflation expectations of firms are an important part of the inflation outlook and can guide the potential path of inflation.
