New York - US stock index futures edged lower on Tuesday, suggesting a second day of weakness as investors continued to hold off from making big bets going into the start of corporate earnings season.
* Alcoa Inc, among the first high-profile names to report, will release its results after the market closes on Tuesday.

* Recent US economic data has been strong, following a dismal start to the year, and market participants are looking to corporate earnings for confirmation that the economy snapped back in the second quarter.

Revenue is seen up 3 percent.
* Market action may be slight until traders get a better sense of how the earnings season is shaping up.

* S&P 500 e-mini futures fell 3 points and were below fair value, a formula that evaluates pricing by taking into account interest rates, dividends and time to expiration on the contract.
Dow Jones industrial average e-mini futures fell 20 points and Nasdaq 100 e-mini futures lost 3.5 points.
* Wall Street had its biggest one-day drop in two weeks on Monday, falling on light volume as investors took profits ahead of the start of earnings.
