How Long Is Too Long?

May 04, 2015 | About:

We were reading two very interesting articles in the past few days. The first was The Science of Hitting's "Process vs. Outcomes, Revisited " of April 7, 2015 and the second was "False Discoveries in Mutual Fund Performance: Measuring Luck in Estimated Alphas”, by L. Barras, O. Scaillet and R. Wermers[1].

Each of these articles helped provoke thinking around the office that finally settled on one specific question: how long is too long for your investment managers to underperform? This is quite relevant today as many value investors – including Nintai – have underperformed the greater markets over the last three (3) year period. With that said, how long of a leash do you think is adequate to understand whether your managers are successful or simply not cutting it?

There's no set answer to this question. Traditionally endowments and pension funds have been very hesitant to replace underperforming outside investment managers. This is probably wise. In a great 2008 study[2], Amit Goyal and Sunil Wahal demonstrated that “excess returns after terminations are typically indistinguishable from zero but in some cases positive. In a sample of round-trip firing and hiring decisions, we find that, if plan sponsors had stayed with fired investment managers, their excess returns would be no different from those delivered by newly hired managers.” That either reflects poorly on the plan sponsors, investment managers, or both.

Retail investors are vastly different. They are capable of surprising agility in their hiring and firing of investment managers. The Quantitative Analysis of Investor Behavior[3] shows the average mutual fund equity investor holds a fund for an average of 3.3 years. For bond fund investors, the average holding period is less than 3 years. It is estimated that retail investors look to begin selling their mutual funds after two quarters of underperformance and individual equities after just one week of losses. Fair weather friends indeed.

And yet there are funds and managers who buck this trend. An example of this is Ken Fisher (Trades, Portfolio) of Fisher Investments. Mr. Fisher comes with the following recommendations:

He has been writing Forbes' prestigious 'Portfolio Strategy' column for over two decades, making him one of the longest-running columnists in the magazine's 85+ year history”.

During his many years of money management and market commentary, Ken has distinguished himself by making numerous, accurate market calls, often in direct opposition to Wall Street's consensus forecasts

“He is the son of legendary investor Philip A. Fisher, and Ken is the only industry professional his father ever trained.

Pretty heady stuff. Writer of several books and talking head on every major business network, Mr. Fisher is omnipresent. He’s been so good at appearing as a true market guru his assets under management have increased from $3B in 2003 to $47B in 2015.

The only problem with this picture is that in some funds his investment calls have underperformed both their bogey and the S&P 500 for nearly every measurable period. As an example, his Purisima Total Return Fund (PURIX) has underperformed the S&P 500 in the 1 Year, 3 Year, 5 Year, 10, Year, and 15 Year time frame. When compared against Morningstar’s recommended bogey of MSCI ACWI Ex US (World Stock) the fund has underperformed its 3 Year, 5 Year, 10 Year, and 15 Year measured periods. Yet by 2015 this fund over $300 million under management.

My goal isn’t to pick on Mr. Fisher. I’m sure he has a reasonable answer for this performance. I bring it up because it seems to fly in the face of rational investment theory. Why would a fund grow assets for so long with such a pedestrian – if not losing – record? How long is too long for investors in the Purisima Total Return Fund?

Part of the answer lies – as always – in investor psychology. One of the great understandings in behavioral finance is that, if you appear to be a winner, then you are a winner, and will likely always be a winner. In other words what goes up will continue to go up. Conversely, the same goes for funds or company stocks that suffer truly horrible losses. The lasting view of investors is that the fund/equity will always be a loser. A great example of this is the annual study conducted by Franklin Templeton[4]. Investors were asked about stock market performance following the crash of 2008. The S&P 500 was down 37% that year but up 26.5%, 15.1%, 2.1%, and 16% in the next respective four years. Investor impressions were exactly the opposite as seen in the graphic below. Respondents in most cases saw these years in very negative terms with most actually believing the markets were down in 2009, 2010, 2011, and 2012.

Why this is important

For individual investors and money managers alike there are some key lessons to be learned as we think about the question of “how long is too long”?

Trends Are Your Friends…Until They Aren’t

As prototypical homo sapiens we are particularly susceptible to riding trends that either work or don’t work for far too long. As money managers we fight it every day. Examples include holding that stock of a company that you insist still has upside potential because it has always gone up or never investing in an industry because thirty years ago it was ridiculously unprofitable. The ability to test your thesis and assumptions on a regular basis is the only way to avoid falling into these traps.

The Only One With the Correct Answer is You

Reaching a definition of “too long” is a wholly subjective answer. Not everyone’s will be the same. For investors in the Purisima Total Return Funds 25 years is not too long. For others the time frame may be days rather than years. In the final analysis only you can make the decision and definition about “too long.” Dependent upon your risk level, investment strategy, and personal needs, you will need to decide if or when to pull the plug.

Data Must be the Core Decision Tool of “Too Long”

At Nintai underperformance or short-term stock drops are absolutely painful. A recent example was our recommendation of Computer Programs and Systems (NASDAQ:CPSI) and having it drop 14% that very day. For us one day of ownership felt like too long. Another was our ownership of Manhattan Associates (NASDAQ:MANH) and our behavioral and emotional difficulty in recognizing the stock was so far overvalued we need to sell out of our total position. These are the moments when we must ruthlessly employ data. Whether we felt holding for reasons of loss or gain, the data will dictate what is too long (or too short) in regards to investing your hard earned capital. Equally, fund investors should employ hard data – historical returns, costs, and portfolios to decide whether you have partnered with a financial manager for longer than the data recommends.

Conclusions

No matter what people will say, there is simply no mathematical formula that can definitively tell how long is “too long.” But we can say that some of the worst decisions we’ve made in regards to this have been emotional decisions rather than a data-driven process. Deciding whether your financial advisor or manager has had enough time to prove themselves is a particularly personal decision. A blend of what allows you to sleep at night, your financial goals and your investing knowledge will dictate an answer to that vexing question. That – combined with historical data – will help investors make an informed decision.

As always we look forward to your thoughts and comments.

As a former 15 year client of Mr Fisher,I can state that his company's customer service is really good;however,the representatives could not and would not explain performance.They are very good at keeping one invested.My personal account just beat the World Index by 40 cumulative percentage points over 15 years.As I undstand,the Purisima Total Return fund is used for employees and those that can't meet the minimum for a private account.I think information and customer contact keeps clients.My account was only part of my assets,and I eventually started managing them myself.I think many of his books are useful in many ways.The books provide a good history of investor behavior which can keep you invested when markets are scary.

Thanks Perots for your comment. As I mentioned, it wasn't my intention to be negative about Ken Fisher (Trades, Portfolio) but point out that underperformance is a subjective thing even when based on hard data. I'm glad your experience was positive. BTW - when you say the could not and would not explain performance what does exactly mean? I'm assuming you got a statement and/or prospectus giving you that information. Thanks again for your comment. Best. - Tom

Actually the return was not considered positive enough by me.When I asked about the relatively poor returns,I would not get an answer that I considered appropriate.It is interesting that at the firm none of the people I would talk to(and there many because of turnover)knew about Warren Buffett (Trades, Portfolio).Ultimately I left after 15 years of poor performance.I think it was long enough- I would rather not pay for that kind of performance.

Hi Perots. Thanks for your answer. I'm sorry to hear about the performance. One thing we've learned at Nintai is that it is essential to explain returns - both good and bad - in a clear and timely fashion. Our investors are owed nothing less. Thanks again for your reply. Best - Tom
