Shareholders in Macronix International (TWSE:2337) have lost 27%, as stock drops 7.8% this past week

For many investors, the main point of stock picking is to generate higher returns than the overall market. But in any portfolio, there are likely to be some stocks that fall short of that benchmark. We regret to report that long term Macronix International Co., Ltd. (TWSE:2337) shareholders have had that experience, with the share price dropping 36% in three years, versus a market return of about 37%. The more recent news is of little comfort, with the share price down 26% in a year. The last week also saw the share price slip down another 7.8%. However, this move may have been influenced by the broader market, which fell 3.8% in that time.

If the past week is anything to go by, investor sentiment for Macronix International isn't positive, so let's see if there's a mismatch between fundamentals and the share price.

To paraphrase Benjamin Graham: Over the short term the market is a voting machine, but over the long term it's a weighing machine. 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.

Over the three years that the share price declined, Macronix International's earnings per share (EPS) dropped significantly, falling to a loss. Due to the loss, it's not easy to use EPS as a reliable guide to the business. But it's safe to say we'd generally expect the share price to be lower as a result!

What About Dividends?

As well as measuring the share price return, investors should also consider the total shareholder return (TSR). 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. In the case of Macronix International, it has a TSR of -27% for the last 3 years. That exceeds its share price return that we previously mentioned. The dividends paid by the company have thusly boosted the total shareholder return.

A Different Perspective

Investors in Macronix International had a tough year, with a total loss of 25% (including dividends), against a market gain of about 32%. However, keep in mind that even the best stocks will sometimes underperform the market over a twelve month period. Longer term investors wouldn't be so upset, since they would have made 0.7%, each year, over five years. If the fundamental data continues to indicate long term sustainable growth, the current sell-off could be an opportunity worth considering. 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.
