The One Thing to Know About Goldman Sachs

I know it sounds ludicrous, but investors often overlook the people in charge of protecting their investments. The idea of gauging a company's leadership plays second-fiddle to other categories of analysis. However, at Fool.com we believe careful study of effective leadership is one of the most important areas of evaluating long-term winning investments.

We like CEOs who actually work for shareholders like us. After all, we're the true owners of the business. When you're deciding whether to invest in a company, failing to vet its CEO is a big mistake. In fact, if you've overlooked the study of a company's leadership, then that's the one important area you should know about before finalizing your investment in the company.

After reviewing thousands of companies over dozens of years, we've found several crucial characteristics of quality management. Today, we'll size up the recent performance of Goldman Sachs's (NYSE: GS) leadership.

How much skin do they have in the game?
Are Goldman Sachs CEO Lloyd Blankfein's interests aligned with shareholders? Here's how the Goldman Sachs CEO's ownership compares to that of other companies in the industry.

Lloyd Blankfein actually owns $294 million worth of Goldman Sachs, or 0.39% of shares outstanding. We Fools prefer CEOs who have higher ownership stakes in their businesses, since that better aligns their interests with shareholders'. However, while we think high insider ownership is a good sign, low insider ownership isn't necessarily a bad one. CEOs may be relatively new, or may have a low percent of shares outstanding, but a high total value of ownership. In Lloyd Blankfien's case, $294 million is a very significant stake.

How well are they using your money?
Return on equity can help investors determine how adeptly management gets the job done. This metric combines how well management is expanding profitability, managing assets, and using financial leverage, all in one ratio. While return on equity isn't foolproof -- managers can manipulate it with excessive leverage, for example -- it does an excellent job of suggesting how effective managers are, and how well they can generate high returns on investors' capital.

Here's a look at Goldman Sachs's recent return on equity:

Despite difficult economic conditions, Goldman Sachs managed to grow return on equity beyond its five-year average. Consistently increasing return on equity suggests that management is either adept at cutting costs and managing assets, or is moving the company into new high-return areas. Along with other major banking institutions, Goldman's return on equity took a nose dive during the financial crisis. Since that time it's managed to pop back up, largely thanks to outsized trading profits. Moving forward, the company's greatest threat may be regulation, as it has a dominant market position in numerous trading areas, and should continue generating outsized returns.

How productive are their workers?
Revenue per employee provides another way to gauge a CEO's effectiveness. If this metric is declining, the company might have a bloated organizational structure, or too many extra employees toiling away at new initiatives that just aren't working out. Either possibility would hint that management isn't effectively running the organization.

As you can see, Goldman Sachs's revenue per employee has moved above its five-year average. Rising revenue per employee can suggest that management's getting better at controlling costs, or encouraging more productivity from its workers. To better see whether Goldman Sachs's management is excelling in this area, let's compare the company to its peer group once again:

Goldman Sachs's revenue per employee isn't just rising -- it's better than its combined peer group. That's quite an impressive feat.

These are just a few of the factors we look for in a company's management. If you can find leaders who continually give shareholders high returns on their capital, and align their interests with yours, you've got a better chance to enjoy market-beating returns for the long haul.
