Generally speaking the aim of active stock picking is to find companies that provide returns that are superior to the market average. And in our experience, buying the right stocks can give your wealth a significant boost. For example, the Assured Guaranty Ltd. (NYSE:AGO) share price is up 95% in the last 5 years, clearly besting the market return of around 58% (ignoring dividends). On the other hand, the more recent gains haven't been so impressive, with shareholders gaining just 20% , including dividends .

To quote Buffett, 'Ships will sail around the world but the Flat Earth Society will flourish. There will continue to be wide discrepancies between price and value in the marketplace...' One imperfect but simple way to consider how the market perception of a company has shifted is to compare the change in the earnings per share (EPS) with the share price movement.

During five years of share price growth, Assured Guaranty actually saw its EPS drop 7.4% per year.

Essentially, it doesn't seem likely that investors are focused on EPS. Since the change in EPS doesn't seem to correlate with the change in share price, it's worth taking a look at other metrics.

We doubt the modest 1.5% dividend yield is attracting many buyers to the stock. The revenue reduction of 15% per year is not a positive. It certainly surprises us that the share price is up, but perhaps a closer examination of the data will yield answers.

It's good to see that there was some significant insider buying in the last three months. That's a positive. On the other hand, we think the revenue and earnings trends are much more meaningful measures of the business. So we recommend checking out this free report showing consensus forecasts

What About Dividends?

When looking at investment returns, it is important to consider the difference between total shareholder return (TSR) and share price return. Whereas the share price return only reflects the change in the share price, the TSR includes the value of dividends (assuming they were reinvested) and the benefit of any discounted capital raising or spin-off. So for companies that pay a generous dividend, the TSR is often a lot higher than the share price return. We note that for Assured Guaranty the TSR over the last 5 years was 112%, which is better than the share price return mentioned above. The dividends paid by the company have thusly boosted the total shareholder return.

A Different Perspective

Assured Guaranty provided a TSR of 20% over the last twelve months. But that was short of the market average. On the bright side, that's still a gain, and it's actually better than the average return of 16% over half a decade This could indicate that the company is winning over new investors, as it pursues its strategy. While it is well worth considering the different impacts that market conditions can have on the share price, there are other factors that are even more important.
