Natural Health Trends shareholders are up 14% for the year (even including dividends). Unfortunately this falls short of the market return. But at least that's still a gain! Over five years the TSR has been a reduction of 10% per year, over five years. So this might be a sign the business has turned its fortunes around. I find it very interesting to look at share price over the long term as a proxy for business performance. But to truly gain insight, we need to consider other information, too. Take risks, for example - Natural Health Trends has 3 warning signs (and 2 which don't sit too well with us) we think you should know about.
