The Standard and Poors 500 index (SPX) closed today at 6013, down 108 points or 1.7%. SPX opened the week at 6122, down 1.8% for the week. Trading volume ran along the 50-day moving average (dma) all week and was only up modestly on today’s sell-off. The only good news was SPX finding support at the 50 dma.

VIX, the volatility index for the S&P 500 options, opened the week at 15.6% and trended sideways until today when VIX spiked to 19% and closed the day at 18.2%.

I track the Russell 2000 index with the IWM ETF, which closed today at 217.8, down 6.5 points or -2.9%. IWM opened the week at 226.2 for a weekly loss of 3.7%. IWM trading volume ran well below the 50 dma all week but spiked to almost double the 50 dma today.

The NASDAQ Composite index closed today at 19,524, down 438 points or 
-2.2%. NASDAQ opened the week at 20,041, setting up a weekly loss of 2.5%. NASDAQ’s trading volume ran along the 50 dma this week.

As I discussed in the last newsletter, this year’s markets have been very choppy, making it challenging for traders. The new administration is moving at record speed, and I think that creates uncertainty about the future. The market effectively prices the future into today’s trading and institutional traders are uncertain what may be around the corner. These changes may be good for the economy and the markets, but that is difficult to ascertain with much confidence.

The FOMC is remaining calm and deliberate and clearly does not want to release the interest rate brakes too quickly.

The S&P 500 is an excellent measure for the overall market, and it has been extremely volatile this year. SPX lost nearly two percent today alone. On the other hand, look at the market’s trading volume. It was only up modestly today. Trading volume actually declined on the NASDAQ Composite. The signs of institutional traders “throwing in the towel” aren’t there - at least not yet.

Each day brings another explanation for the weakness. Yesterday it was blamed on the weak forward guidance Walmart delivered Wednesday evening. Today it was blamed on reports of United Health being the subject of a DOJ investigation into Medicare billing. The market is nervous and tips over easily. Investors Business Daily downgraded their recommended stock market exposure yesterday and then again today.

Be cautious.
