Thursday saw the market finally begin to react, to reprice based on the current environment. But why? Was it earnings? Was it China? Was it the Federal Reserve? How about a little bit of everything. News of a potential default in China along with a weak report on Chinese manufacturing (the Markit/HSBC purchasing managers' index) causes investors around the world to re-assess risk.
Then, the Fed floated the idea of increased taper at next week's Federal Open Market Committee meeting to test the anxiety of investors and see how the market would react. As investors digested the news, it only accentuates the weakness in earnings — the weakness that many investors previously paid no attention to because as long as the Fed supports, then investors seem to be at ease. But once investors get the sense that the Fed is pulling out — because the economy is so much better — they all of a sudden need to reassess. The market's reaction Thursday only highlights the fact that investors do not really believe the story.
You see, month-to-date, we are told that of the 100 S&P companies that have reported so far — 73 percent have beaten estimates while 66 percent have exceeded sales guidance while less than 50 percent report better revenues. But with rates held at artificially low levels, where is the investor to go?

At some point, companies are going to have to start really producing revenue growth that translates into real earnings growth. Until that happens, then I suspect the market will continue to struggle and the correction that so many analysts/strategists are looking for will materialize.
So investors should not be surprised to see the market test support levels in the coming days. Technically we have broken near-term support at 1825 so look for the 50-day moving average at 1810 to be the next level to test.

Next week brings more earnings and the Fed statement. Depending on what the Fed says will dictate how investors react. If they do not believe the data, then expect further pressure. If the Fed all of a sudden suggests that tapering will remain status quo, then expect a bit of a relief rally. Either way — investors will need to remain vigilant as they build and create portfolios for 2014.
