Nike Inc NKE.N slid 6.3% after forecasting lower than expected first-quarter revenue. By Stephen Culp NEW YORK, June 28 (Reuters) - Wall Street slid on Tuesday with early gains reversing to a broad sell-off on the heels of dire consumer confidence data, which dampened investor optimism and stoked recession fears. "It has been a very bad start to the year, and 1970 is a pretty good analog to where we are now, with war and inflation," said Peter Tuz, president of Chase Investment Counsel in Charlottesville, Virginia.
