Last week brought even more stock market weakness and volatility as the selloff became self-perpetuating, with nobody mid-day on Wednesday wanting to be the last guy left holding equities. Hedge funds and other weak holders exacerbated the situation.

Volatility continues to increase in the stock market and many of the leaders are breaking down. In particular, semiconductors took a rather big hit when one of the bellwethers warned of weakening global demand. Nevertheless, despite the significant headwinds, I do not think this spells the end of the bull market. But the technical damage to the charts is severe, particularly to the small caps, which are in full-blown correction mode. The large caps must show leadership and rally immediately -- or it will put at risk the critical and widely-anticipated year-end rally.

This seasonally weak time of the year has proven reliable once again. As I observed last week, the volatility index often hits a peak in October but has never hit a trough during this notorious month. Last week, I warned of more downside in stocks before any new highs are challenged. It was the type of week that tests investors’ bullish conviction, and it was way overdue.

Yes, the market showed significant weakness last week for the first time in quite a while. In fact, the Dow Jones Industrial Average moved triple digits each day. But it was all quite predictable, as I suggested in last week's article, and certainly nothing to worry about. Now the market appears to be poised for a modest technical rebound, and longer term, U.S. equities should be in good shape for a year-end rally. However, I still believe more downside is in order before any new highs are challenged.

Stocks were able to leverage some optimistic news and dovish words from the Fed to take another stab at an upside breakout attempt last week. Although readers have sometimes accused me of being a permabull, I am really a realist, and the reality is that the slogans like “The trend is your friend” and “Don’t fight the Fed” are truisms. And they have worked.

Although the stock market displayed weakness last week as I suggested it would, bulls aren’t going down easily. In fact, they’re going down swinging, absorbing most of the blows delivered by hesitant bears. Despite holding up admirably when weakness was both expected and warranted, and although I still see higher highs ahead, I am still not convinced that we have seen the ultimate lows for this pullback. A number of signs point to more weakness ahead.

Was that really a breakout? With the S&P 500 struggling around the 2,000 level for the past two weeks, Friday’s strong finish might seem like a bullish breakout. But the market has already given us a couple of false breakouts at this level, and although I see higher prices ahead, I’m still not convinced that we have seen all the near-term downside that Mr.

Bulls are having their way as summer draws to a close. Indeed, U.S. stocks and bonds seem to be the best and safest place to invest in a global economy that is at once hopeful and cautious, with lots of available cash hunting for attractive returns. But now the S&P 500 must deal with the ominous 2,000 level.

As many investors enjoy the final weeks of summer, some optimistic bulls seem to be positioning themselves well ahead of Labor Day in anticipation of a fall rally. Indeed, last week’s action was impressive. After only a mere 4% correction, investors continued to brush off the disturbing violence both at home and abroad, and they took the minor pullback as their next buying opportunity.

Stocks saw elevated volume and volatility last week, and the 100-day simple moving average on the S&P 500 proved to be the proverbial line-in-the-sand for bullish investors. I opined last week that the market seemed to have sufficiently cycled back down to oversold territory, so with a little more technical consolidation and successful testing of nearby support levels, the next move higher could easily commence at any time. So, the question remains as to whether that was the big new buying opportunity, or whether more backing-and-filling is needed.
