It seems that lately there have been several days with all indices in the green all day, and yet trin has been markedly > 1. trinr and trinq seem to have been at appropriate levels, just the straight trin out of whack. Is this a case of 1 stock down on the day with enormous volume?
A TRIN of >1 means that there is more volume moving into declining stocks than advancing stocks. The distribution is unknown. AI x DV ------- DI x AV
Specific to Monday (3/21), there were two declining stocks with very high volume: Citigroup and Sprint Nextel.
