Earnings growth of 48% over 1 year hasn't been enough to translate into positive returns for London Stock Exchange Group (LON:LSEG) shareholders

It's easy to match the overall market return by buying an index fund. When you buy individual stocks, you can make higher profits, but you also face the risk of under-performance. Unfortunately the London Stock Exchange Group plc (LON:LSEG) share price slid 20% over twelve months. That contrasts poorly with the market return of 15%. On the bright side, the stock is actually up 7.3% in the last three years. The share price has dropped 23% in three months.

After losing 3.3% this past week, it's worth investigating the company's fundamentals to see what we can infer from past performance.

Trump has pledged to "unleash" American oil and gas and these 15 US stocks have developments that are poised to benefit.

There is no denying that markets are sometimes efficient, but prices do not always reflect 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.

Even though the London Stock Exchange Group share price is down over the year, its EPS actually improved. Of course, the situation might betray previous over-optimism about growth.

It's surprising to see the share price fall so much, despite the improved EPS. But we might find some different metrics explain the share price movements better.

With a low yield of 1.6% we doubt that the dividend influences the share price much. London Stock Exchange Group managed to grow revenue over the last year, which is usually a real positive. Since we can't easily explain the share price movement based on these metrics, it might be worth considering how market sentiment has changed towards the stock.

It's good to see that there was some significant insider buying in the last three months. That's a positive. That said, we think earnings and revenue growth trends are even more important factors to consider.

A Different Perspective

London Stock Exchange Group shareholders are down 19% for the year (even including dividends), but the market itself is up 15%. However, keep in mind that even the best stocks will sometimes underperform the market over a twelve month period. Unfortunately, last year's performance may indicate unresolved challenges, given that it was worse than the annualised loss of 0.2% over the last half decade. We realise that Baron Rothschild has said investors should "buy when there is blood on the streets", but we caution that investors should first be sure they are buying a high quality business.
