Did not take much to sell off

Dear Readers, looking at the chart of pressure and summation , we notice that it did not take much to sell this market. In fact, look across it and you will see that it took less and less sell pressure levels ( summation levels) to create the sell off's. Is this another way to say that these markets have become narrower and narrower in leadership. You bet it is. That is exactly the statement the Charts above are making.
