Plenty of market-moving news will break this week: One way or another, big changes loom due to Washington's budget fight; and Home Depot, Groupon, Best Buy, RadioShack and Monster will report earnings.
RadioShack shouldn't be surprising anyone on the downside when it reports its quarterly results, but that's exactly what happened on Tuesday. Net sales fell 3% to $1 billion, weighed down by a 1.6% decline in same-store sales. Analysts were banking on a slight top-line uptick.
There was a time when RadioShack mattered -- it was the easiest place to pick up those tech items you had to have, from odd-sized batteries to coaxial cables. Now you can get that stuff everywhere, and RadioShack is dying so fast that even Wall Street's analysts can't keep up with its decline.
