) -- According to Paul La Monica at

CNN Money

, insider selling is near its highest levels in a decade.

Specifically, nearly 1,800

S&P 500

executives cashed in shares over the most recent three-month period.

Does this mean that the smart money is leaving equities? Or do permabears love to point at everything and anything that strengthens their permanently pessimistic viewpoint?

Historically, insider buying is far more worth following than corporate insider selling. Executives may sell shares to diversify assets, prepare for retirement, make a large discretionary purchase or protect against stock price depreciation.

On the flip side, however, an insider's chief motivation to buy company stock is to make money from capital gains; he/she thinks the stock price is going higher.

Still, the potency of insider information -- buying or selling -- is suspect. For example, the majority of executives in 2008 were buying before the systemic collapse. In fact, according to Mark Hulbert, most insiders were more bullish in January 2008 than they were in October 2007, when the recession first began.

Questions regarding the helpfulness of insider purchasing info also arise when one compares the

Guggenheim Insider Sentiment Fund

(NFO) - Get Report

against an appropriate benchmark.

This ETF seeks to replicate the performance of the Sabrient's Insider Sentiment Index where Sabrient developed a quantitative stock-picking method based on insider buying trends. NFO is classified as a mid-cap blend fund, which implies that it should be compared to the S&P Mid Cap 400. Note: iShares tracks the index with

iShares S&P Mid Cap 400

(IJH) - Get Report


Since the September 2006 inception date, NFO has outperformed IJH by 8%. This may give some credence to the notion that insider purchases can provide insight on when to buy.

Executives may sell for reasons other than to protect principal, and this may make insider selling data less powerful. Still, there are instances when insider selling has been informative.

Consider July of 2011. Corporate insiders were selling shares of their


- and AMEX-listed companies at the fastest rate since the early 1970s. The reality that many were selling near the summer lows rather than selling near the spring highs of April likely demonstrate that execs can come unglued -- just like the general public.

Nevertheless, when one considers the accumulation of information -- falling Treasury bond yields, dollar outflows from global equity funds, benchmark declines since earnings season began, increasing CBOE VIX volatility, sovereign debt crisis flare-ups -- the insider selling data begin to look prescient.

You don't have to run screaming for the exits, though. It makes far more sense to employ appropriate ETF hedges as well as use sensible stop-loss orders; in that manner, you won't be prone to selling stock ETFs in an undisciplined frenzy.
