Some technical comments on the market: The Nasdaq and Nasdaq 100 found support where we hoped they would, at the downtrend lines broken last month (3900 on the Nasdaq, 3750 on the Nasdaq 100). However, the indexes so far haven’t rallied with much strength, so another test of those levels may be in the cards. A break below those levels would likely lead to a wider sell-off. To the upside, the Nasdaq faces resistance at around 4000, and then again at 4100. The Dow and S&P 500 continue to find support at 11,200 and 1490, respectively. The Dow may be forming a head-and-shoulders top here; a clean break of 11,200 would likely carry the index back to 11,000. Critical support is just under 10,900, the upper boundary of the Dow’s bearish diamond pattern, which the index broke out of last month. Resistance on the Dow is 11,300 and 11,400, and on the S&P, 1500 and 1507. First support on the ISDEX is 790-800, which the index undercut today but then recovered. Critical support is just above 700, which is now the intersection of the index’s March downtrend and May uptrend lines. To the upside, the ISDEX’s recent rally was capped by the 50% retracement level of 850.
