NEW YORK, April 11 (Reuters) - With the Dow hitting so many fresh highs of late, some investors may be dusting off the 1999 bestseller “Dow 36,000,” a book that briefly made “irrational exuberance” seem quite rational.
Even Alan Greenspan, the former Federal Reserve Board chairman who coined that description of market sentiment before the dot-com bust, has mused publicly that stocks are undervalued.
But at least one group has been actively selling into the rally: corporate executives in the best position to know about their companies’ prospects. In February, officers and directors sold $35.30 worth of shares in their own companies for every dollar they put into stocks.
That is the highest monthly ratio since TrimTabs Investment Research began tracking the data in 2004, says David Santschi, chief executive of TrimTabs, based in Sausalito, California. A more typical ratio is around 8 to 1 of selling over buying.
“It is a sign that company officers and directors think the market is richly valued,” Santschi said.
Looking at price-to-earnings ratios, a common metric for valuing companies, they may have a point: The SP500 is now trading at 18.35 times trailing earnings, up from 16.26 a year ago. The long-term average for the index is 15.49.
Indeed, the trend since May 2012 has shown company insiders selling rather than buying by a larger-than-usual margin. In the first quarter of 2013, insiders sold $11.86 billion worth of shares, compared with barely $1 billion in purchases.
For retail investors who are finally getting over their fear of the market, it is a worrisome indicator - though not necessarily a “race for the exits” signal. Companies that have high and rising levels of insider selling often follow that up with share price underperformance, market studies show.
But company officers and directors - who must file records of their purchases and sales with the U.S. Securities and Exchange Commission - have many personal reasons for selling that don’t necessarily point to a market or individual company collapse.
Executives sell for a range of reasons: Sometimes they just want to cash out some options to pay a tuition bill or put a down payment on a vacation home. Others want to reduce their dependence on any single company’s future - or pull money out at an opportune time.
The list of insiders involved in large sales in early April includes Google Inc. co-founder Sergey Brin ($67.5 million worth of shares); LinkedIn Corp. co-founder Reid Hoffman ($14.5 million); Gilead Sciences Inc. CEO John Martin ($13.6 million); and Dollar General CEO Richard Dreiling ($12.3 million).
A Dollar General spokesman said Dreiling’s stock sale was part of a “planned diversification program,” and LinkedIn offered that Hoffman’s “automatic stock sales are part of a personal investment diversification strategy.”
Gilead Sciences had no comment on Martin’s transaction.
Google Executive Chairman Eric Schmidt sold over $191 million of company stock in one February week - after a stellar year that left the share price hovering around $800.
As the sale amounted to about 42 percent of his stake, the company released this statement: “This is a routine diversification of assets, and Eric remains completely committed to Google.”
Even so, when so many insiders sell instead of buy, it becomes an intriguing clue to their collective take on the market - and not an upbeat clue.
“Rising selling to net buys is a net negative for the market,” said Kristen Hendrickson, an analyst with The Leuthold Group, a Minneapolis-based institutional research firm.
Leuthold analysts have seen unusually high selling patterns among the so-called “big-block” insider stock transactions they track - transactions of at least $1 million in total value, or a minimum of 100,000 shares.
At the end of 2012, there were 150 more big-block sales transactions than purchases over a 10-week period. That compares with a 10-week moving average of 60 more big-block sales than purchases since 1982, when Leuthold began tracking that data.
“It is a critical indicator of the sentiment of corporate executives, and what they are seeing in the future,” said Hendrickson.
The ratio of insider selling to buying has reached sky-high levels two other times: In mid-2000 as the dot-com bubble burst, the average spread of big-block sales over buys crested close to 250. In 2006, before the financial crisis hit, the same average hit a peak of 220.
Recently it has hovered around 125 - not quite as high, but still more than double the long-term average.
Of course, insider selling is just one indicator of market direction. Leuthold’s Major Trend Index tracks 130 different components, only two of which measure insider activity (number of transactions and total dollar volume involved).
Leuthold analysts say they remain bullish about the market’s prospects as a whole, thanks to other positive indicators, such as market momentum.
That said, the negative signal that insider buying throws off is often company-specific as well as market-specific.
Stocks with significant insider selling tend to underperform the market, particularly after one to 12 months, said Jonathan Moreland, research director at InsiderInsights.com.
“The ultimate situation you are looking for is three or more insiders at a company, all of whom have great track records at trading company shares, all selling big dollar amounts that add up to a large percentage of their holdings,” Moreland said.
Stocks with significant insider buying rose 87.1 percent between the beginning of 2009 and April 2010, more than double the 36.8 percent gain recorded by companies with big insider selling, according to InsiderInsights.com.
Insider sales in the aggregate are much like national home-price averages: they don’t offer enough specific detail. Just as real estate prices in one area could be rising or falling, so too will insider buying and selling vary with each individual company.

The best advice for individual investors is to use insider selling data in conjunction with other indicators, TrimTabs’ Santschi said. Buy-back programs paired with significant insider buying is a positive signal, while buybacks combined with insider selling might mean it’s time to take some profits.
