The New Challenges Of Price Discovery: What Investors Need To Know

Investing in the Age of High-Frequency Trading, Falling Volumes and Widening Bid-Ask Spreads

As investment managers, one of our most important fiduciary responsibilities is buying and selling stocks for the best possible price and execution. We do this by using the statistical strategies I’ve previously covered, from monitoring
Despite the challenge, we try to take advantage of the volatility that other investors might flee from. Decisions to buy or sell a company are first fundamentally driven, and then trading is based on statistical analysis of fund flows, volatility over different time periods and relative performance to the gold indices we strive to beat. For the Gold and Precious Metals Fund (USERX), it’s the FTSE Gold Mines Index; for the World Precious Minerals Fund (UNWPX), the NYSE ARCA Gold MinersIndex.

Our style resembles that of the Navy SEALS, in that we prefer to be nimble, surgical and tactical. During the bear market that ran from mid-2011 until February 2014, we nibbled rather than munched on inexpensive companies that were lagging in relative performance over one day, one month and one quarter. And when these companies showed a surge in price and volume, we often trimmed our holdings rather than sold outright. This incremental “nibbling” strategy is a little like investment reconnaissance, enabling us to test our conviction in a company before taking a weightier position.

Another disruptive factor to price discovery has been the proliferation of exchange-traded funds (ETFs). Accounting for more than 30 percent of trading volume in the markets, some ETFs are influencing the markets they track and impacting their underlying holdings. A study by Goldman Sachs confirmed that ETF trades influence stock prices. The study looked at which individual stocks move more with the dynamics of the ETF than on their own fundamentals and found that those stocks most affected by ETF activity are in the Russell 2000, probably because of their lower levels of liquidity, lower volume and cheap prices.

We’ve witnessed this same phenomenon with some junior gold stocks in the GDXJ. A gold stock can have a significant price move based not on changes to its fundamentals or a corporate event but rather shifts in sentiment toward gold that is compounded by fund flows. The inclusion or exclusion of a stock in the underlying index can result in a flurry of disruptive trading unrelated to changes in the company’s fundamentals.

Just as one man’s trash is another man’s treasure, one man’s fear of volatility is another man’s opportunity. Part of successful active management is not getting discouraged, learning to adapt to a changing climate and coming to terms with the market’s often erratic behavior.

But the erratic behavior has only ramped up in recent years.

HFT: Trading at the Speed of Greed
As I said earlier, price discovery has become much more difficult in recent years because of growing high-frequency trading (HFT), dark pools and non-exchange trading—all of which have changed, perhaps irreversibly so, the formation of capital in the investment industry.
