New Highs and New Lows

Another indicator reflects market breadth, a measure of the true internal strength (or weakness) of the stock market. nus is the new high/new low indicator, including various derivatives of the related data. The number of issues making new highs, measured on either a daily or a weekly basis, is the number that reach new 52-week highs in price at any time on a given day or, for weekly-based readings, at some point during the week. This would be a price level higher than any level recorded in the previous 52 weeks. The number of issues falling to new lows refers to the number of issues whose prices have declined to their lowest level in the most recent 52 weeks.
It goes without saying that it is more positive when large numbers of issues advance to new highs than when the numbers of stocks in rising trends diminish. It is more negative when large numbers of issues keep falling to new lows than when increasing numbers of stocks find support, perhaps beginning new uptrends.
