We are in a very concentrated environment. The Nasdaq 100 is up 16.2% year-to-date. Four stocks – Alphabet, Nvidia, Micron, and Intel – are responsible for 8.4% points, or 52.3% of the gains. With the market hitting all-time highs, only 40% of Nasdaq stocks are above their 200-day moving averages, so it's a selective environment. Money has chased a small list of names which is producing a number of climax moves in individual names. Examples include: $INTC, $MU, $SNDK, $BE, $STX, $AMD. There is some serious momentum in these names, but investors need to be careful of getting caught up in the emotion that comes with a parabolic rise. The nature of this market has been one of concentration and selectivity. With many stocks becoming extended, the landscape is becoming more selective. The bull market is intact, but with pockets of froth forming.
