Finviz has restaurants as today's leading industry, however that was skewed by SNS having a 20 for 1 reverse split, which Finviz missed and have it listed as a 2000% gain, so I'll go with the next leading industry, semiconductors - memory chips. Here are the top 4 in market cap, all with really nice chart patterns. The small cap of the group, RMTR, is also the laggard, and is near a strong support level. It might bear watching.
