The stock market ended mixed on Monday after trading in a very tight range for most of the session. Volume, an important indicator of institutional sponsorship, was lower than Friday’s levels on both major exchanges which suggested large institutions were not aggressively selling stocks. Advancers led decliners by about a 10-to-9 ratio on the NYSE and were roughly even on the Nasdaq exchange. There were 29 high-ranked companies from the CANSLIM.net Leaders List that made a new 52-week high and appeared on the CANSLIM.net BreakOuts Page, less than the total of 45 issues that appeared on the prior session. Leadership among high-ranked growth stocks had dried up in recent weeks, so the expansion in new highs this week has been a welcome improvement. New 52-week highs solidly outnumbered new 52-week lows on the NYSE and on the Nasdaq exchange.
