As everyone knows, stocks do not go up in a straight line, not even during the holidays. So although the future looks bright for U.S. equities as the major indexes continue to hit or challenge new highs, the market has been gasping for a breather to gather bullish conviction. My fear has been that we might not see it until January, which likely would have resulted in a more severe correction at that time. But falling oil prices and a weak Energy sector seems to have introduced a reason to sell this week.

With warmer weather arriving to melt the early snowfall across much of the country, investors seem to be catching a severe case of holiday fever and positioning themselves for the seasonally bullish time of the year. And to give an added boost, both Europe and Asia provided more fuel for the bull’s fire last week with stimulus announcements, particularly China’s interest rate cut. Yes, all systems are go for U.S. equities as there really is no other game in town.

Investors in U.S. equities seem to have embraced a new market paradigm in which upside spikes come more swiftly than the downside selloffs. Remember when it used to be the other way around? When fear was stronger than greed? The market is consolidating its gains off the early-October V-bottom reversal, and no one seems to be in any hurry to unload shares this time around, with the holidays rapidly approaching and all.

After displaying a classic V-bottom reversal to what turned out to be a quick and anemic attempt by the bears to bring about a real correction, bullish fervor is becoming contagious, especially as the traditionally strong holiday season approaches. Indeed, the brief selloff was snatched up as a buying opportunity as I predicted it would, but my concerns about the market consolidating and struggling to hit new highs before year end were quickly dismissed. So, with nothing but blue skies overhead, will the party simply roll on?

Bulls showed renewed backbone last week and drew a line in the sand for the bears, buying with gusto into weakness as I suggested they would. After all, this was the buying opportunity they had been waiting for. As if on cue, the start of the World Series launched the rapid market reversal and recovery. However, there is little chance that the rally will go straight up. Volatility is back, and I would look for prices to consolidate at this level before making an attempt to go higher. I still question whether the S&P 500 will ultimately achieve a new high before year end.

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.
