The Market
The market was generally down in the past week. All of the major metrics (S&P 500, NASDAQ, Wilshire 5000 and the Russell 2000) were down except the DOW and the VIX. The DOW was up less than 1%, but the VIX was up 19.5%. The Russell 2000 was down the most at 4.26%. The rising VIX suggests increased volatility in the market in the next month, but increased volatility may present greater opportunity for profitable options activity.
Last week we looked at market trends as expressed by the Dow Jones Index, a collection of 30 blue chip, large-cap stocks. This week we examine the Wilshire 5000, which is the broadest index of the market containing 6700 US companies. Stocks are included in this index if they satisfy the following three rules:
1. The company has its headquarters in the United States.
2. The stock is actively traded on an American stock exchange.
3. The stock has pricing information that is widely available to the public.
The Wilshire 5000 is not only the broadest surrogate of the US market, but some say the best representation of market behavior.
Figure 1: Wilshire 5000 Index – 18 Year History
In the past 18 years the Wilshire 5000 has had three up periods and two down periods. From 1 May 1993 until 1 January 2001 the Wilshire 5000 rose from 4,438.55 to 12,181.33 or 174% in less than 8 years. From 1 February 2003 until 1 October 2007 this index rose from 7,896.94 to 15,673.36 or 98% in less than 5 years. From 1 February 2009 until 1 January 2011 the Wilshire 5000 rose from 7,473.97 to 13,499.30 or 80+% in less than 2 years. The two down trends began on 1 January 2001 and 1 October 2007. From 1 January 2001 until 1 February 2003 the index fell 4284.39 or 35%. From 1 October 2007 until 1 February 2009 the Wilshire 5000 fell 8199.39 or 52%. Two observations seem evident. First, clearly the up trends (bull market) are longer than the down trends (bear market). Second, this index seems to be oscillating about a mean value of approximately 11,000. In statistics this phenomena is called “mean reversion.” I call it “market elasticity”. What goes up must come down and vise versa. The summary of major market metrics for the past week can be seen in Table 1.
