You can't keep a good market down, so why is everyone so darn worried about the stock market? Could it be that too much of a good thing may be dangerous to your financial health? If so, someone should tell the bulls.

Truly, no one should be complaining. Here we are at the end of May, normally a month where the markets come under selling pressure, and we are a mere five points away from the S&P 500 Index's all-time high. The contrarian in me says that too many people are waiting for the shoe to drop right now, so it probably won't.

Officially, it is the Memorial Day weekend that kicks off the herd migration from Wall Street's gray canyons and valleys to more amenable vistas. Highly-polished Wing-tips are exchanged for Gucci sandals, as the high and mighty head for the over-crowded beaches and multimillion dollar "cottages" of Long Island and the Hamptons.

Those who remain are the young and ambitious. Without much trading authority, they will have a hard time moving markets. Nonetheless, they will attempt to make a killing for their bosses at the expense of the rest of us. As market volume dries up this summer, it is a toss-up on whether markets become even more volatile or simply wallow in apathy and neglect.

In my career, I have seen both during the summer doldrums. In recent years, the markets have tended to be more volatile with fairly large declines in June and July. In other periods, you could hear a pin drop for weeks at a time on New York trading floors. I'm betting we see more volatility than less.

While the markets continue to grind higher so does the short interest in the stock market.

Short interest is the quantity of stock shares that investors have sold short but not yet covered or closed out. Many strategists use short interest as a market-sentiment indicator, since it indicates how many investors think a stock's price (or market) is likely to fall. Both the short interest aggregate dollar amount of the S&P 500 Index and short interest ratio (days to cover or buy back these shorts) are at levels not seen since mid-2007. We all know how that ended for investors.

The markets continued to make new highs until the end of the year and then subsequently crashed in 2008-2009.

Last week the markets touched my S&P 500 Index target of 1,900 — briefly. It was so quick that I half hoped we would make another stab at that level and possibly break it. It appears we are trying to accomplish that as I write this. Markets are never neat and tidy so if we break this level to the upside, I would expect a bout of short-covering which could propel the markets higher by another 20-40 points quickly. At the same time, I think too many people are bearish for a sell-off right here and now. If we were to see a fast jump higher and a panic stampede into the market at that time we just might be set up for a last hurrah.

Have a happy Memorial Day weekend. But while you are grilling, swimming or just plain having fun, do me a favor. Take a moment to remember our servicemen and women both past and present. I know I will be remembering my buddies in Vietnam that didn't make it. Semper Fi
