Insider activity is closely monitored because it can often be used as a indication of a company's future, or at least what insiders expect for their company's future. After all, who knows the inner-workings of a company better than those that work there?

Vicker's Weekly Insider Report, published by Argus Research, regularly conducts analysis on the number of shares that insiders collectively sell in the open market and the number that they have purchased. The data is compiled as a sell-to-buy ratio.

Four decades worth of data place the mean sell-to-buy ratio between 2-1 and 2.5-1. Lower readings signal bullish sentiment, while high ratios are considered to signal more bearish sentiment.

What are company insiders telling us?
So, what's going on right now? According to Vicker's, the ratio for the week ending last Friday was 3.79-to-1, which is well above its long-term average.

But don't get too concerned. Mark Hulbert of Market Watch writes, "You should be careful not to read too much bearish significance into this recent level ... It's entirely natural for insiders to pick up the pace of their selling in the wake of a market rally -- and, therefore, not particularly surprising."

What's more, "The Vickers' ratio is no where near as high as the level to which it reached earlier this year, in the weeks leading up to the April 29 bull market high. In some of those weeks, in fact, the sell-to-buy ratio was above 7-to-1."

Ultimately, the ratio isn't very telling right now. "Your reaction to recent insider behavior will depend on whether you are inclined to see the glass as half full or half empty."
