The one-year underlying earnings growth at TFF Group (EPA:TFF) is promising, but the shareholders are still in the red over that time

Passive investing in an index fund is a good way to ensure your own returns roughly match the overall market. When you buy individual stocks, you can make higher profits, but you also face the risk of under-performance. For example, the TFF Group (EPA:TFF) share price is down 31% in the last year. That's well below the market decline of 1.3%. On the other hand, the stock is actually up 9.8% over three years. The falls have accelerated recently, with the share price down 24% in the last three months.

After losing 8.5% this past week, it's worth investigating the company's fundamentals to see what we can infer from past performance.

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 flawed but reasonable way to assess how sentiment around a company has changed is to compare the earnings per share (EPS) with the share price.

Even though the TFF Group share price is down over the year, its EPS actually improved. It's quite possible that growth expectations may have been unreasonable in the past.

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.

TFF Group's revenue is actually up 11% over the last year. Since the fundamental metrics don't readily explain the share price drop, there might be an opportunity if the market has overreacted.

A Different Perspective

While the broader market lost about 1.3% in the twelve months, TFF Group shareholders did even worse, losing 30% (even including dividends). Having said that, it's inevitable that some stocks will be oversold in a falling market. The key is to keep your eyes on the fundamental developments. Regrettably, last year's performance caps off a bad run, with the shareholders facing a total loss of 3% per year over five years. 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.
