Investors one-year losses continue as Vesuvius (LON:VSVS) dips a further 15% this week, earnings continue to decline

Investors can approximate the average market return by buying an index fund. Active investors aim to buy stocks that vastly outperform the market - but in the process, they risk under-performance. That downside risk was realized by Vesuvius plc (LON:VSVS) shareholders over the last year, as the share price declined 32%. That's disappointing when you consider the market declined 3.3%. At least the damage isn't so bad if you look at the last three years, since the stock is down 3.5% in that time. The falls have accelerated recently, with the share price down 20% in the last three months.

Given the past week has been tough on shareholders, let's investigate the fundamentals and see what we can learn.

While markets are a powerful pricing mechanism, share prices reflect investor sentiment, not just underlying business performance. By comparing earnings per share (EPS) and share price changes over time, we can get a feel for how investor attitudes to a company have morphed over time.

Unhappily, Vesuvius had to report a 24% decline in EPS over the last year. The share price decline of 32% is actually more than the EPS drop. So it seems the market was too confident about the business, a year ago. The P/E ratio of 9.46 also points to the negative market sentiment.

What About Dividends?

When looking at investment returns, it is important to consider the difference between total shareholder return (TSR) and share price return. The TSR incorporates the value of any spin-offs or discounted capital raisings, along with any dividends, based on the assumption that the dividends are reinvested. Arguably, the TSR gives a more comprehensive picture of the return generated by a stock. As it happens, Vesuvius' TSR for the last 1 year was -29%, which exceeds the share price return mentioned earlier. The dividends paid by the company have thusly boosted the total shareholder return.

A Different Perspective

While the broader market gained around 3.3% in the last year, Vesuvius shareholders lost 29% (even including dividends). However, keep in mind that even the best stocks will sometimes underperform the market over a twelve month period. On the bright side, long term shareholders have made money, with a gain of 1.8% per year over half a decade. It could be that the recent sell-off is an opportunity, so it may be worth checking the fundamental data for signs of a long term growth trend. It's always interesting to track share price performance over the longer term. But to understand Vesuvius better, we need to consider many other factors.
