We watch market indicators and use our best judgment and training to determine when to use each strategy. Our guidelines and processes are based upon experience and analysis, not emotion. Active investing is a strategy where an investor attempts to beat the market by trading individual stocks, bonds, or other securities. To fully appreciate the result in Proposition 5, note that the overall inefficiency η can be seen as the sum of the inefficiencies of n uncorrelated portfolios as given by Equation (20). In other words, factor inefficiency dominates overall market inefficiency to a surprising extent. In standard theories of informed trading, investors naturally fall into two groups—informed and uninformed—while real-world investors are classified as active or passive, and we have made the natural link between these dichotomies.
Morgan Stanley Wealth Management is not acting as a fiduciary under either the Employee Retirement Income Security Act of 1974, as amended or under section 4975 of the Internal Revenue Code of 1986 as amended in providing this material. Asset allocation and diversification do not assure a profit or protect against loss in declining financial markets. Equity securities may fluctuate in response to news on companies, industries, market conditions and general economic environment. While S&P 500 index funds are the most popular, index funds can be constructed around many categories. For example, there are indexes composed of medium-sized and small companies. Other funds are categorized by industry, geography and almost any other popular niche, such as socially responsible companies or “green” companies.
Pros and cons of passive investing
So uninformed and passive investors both minimize cost, presumably both maximize their performance, and perhaps both have portfolios based on E(q|p), which we explore based on the following assumptions. First, note that while passive indexes typically follow relatively simple rules, competition between index providers could lead these rules to become optimal subject to minimum costs, just like the portfolios of uninformed investors in the model. The economy has S¯ investors with initial wealth W and constant absolute risk aversion (CARA) coefficient γ. These investors search for an active manager, allocate to a passive manager, or directly invest in the financial market. Specifically, I investors choose to search for an informed active manager, Sp investors choose passive management, and the remaining S¯−I−Sp are self-directed.
The cost of active investment can also increase in I, though, if the search cost rises sufficiently. Given that over the long term, passive investing generally offers higher returns with lower costs, you might wonder if active investing ever warrants any place in the average investor’s portfolio. While active investing tends to focus on individual securities, passive strategies generally involve purchasing shares of index funds or ETFs that aim to duplicate the performance of major market indexes, like the S&P 500 or Nasdaq Composite.
Even when adjusting returns with the estimated arithmetic value of the survivorship bias, a completely exact value will not be identifiable because each sample has a different degree of survivorship bias. The second limitation of this study is also unique to the sampling approach and data collection. As pointed out, there is a distinction made in the selection process of the funds regarding their structure.
What Is Active Investing?
Results show that mutual fund performance outperforms the benchmark yearly on average by 1.3%. A noteworthy corporate study by Philips, Kinniry, & Walker (2014) also advocates active investing. 2800 actively managed funds within an investment horizon of three decades were assessed to gain insights on the cyclicity of fund performance. In one of the three decades, 63% of all US equity mutual funds outperformed the market portfolio returns (Philips, Kinniry, & Walker, 2014). Our results complement those of Glasserman and Mamaysky (2018), who also provide conditions for higher macro-inefficiency with a single factor and an exogenous definition of macro versus micro information, but endogenous information choices.
- Asset allocation and diversification do not assure a profit or protect against loss in declining financial markets.
- In a similar spirit, Peress (2005) shows that a decreasing market-participation cost leads to more participation and, in particular, more passive participation.
- We have also seen that the dictum holds only under certain conditions, but we will next show that the dictum always holds when the number of securities is large enough.
- Passive investing involves investing over the long term with very limited buying and selling.
- According to the well-known SPIVA (S&P Indices vs. Active) scorecard report of 2022, 95% of U.S. active equity funds underperformed their respective S&P indexes over the last two decades, through 2021.
- Hence, our framework presents a step toward a theory of optimal security indexes.
A clear example was in the year-end 2018 report, when more than 58% of Mexican active funds outperformed the S&P/BMV IRT. The numbers suggest that active managers’ outperformance relative to the benchmark may exist, but rarely. Third, the model makes predictions on the impact of the ongoing, widespread reductions in the cost of passive management on capital markets and the industrial organization of the asset management industry. In particular, we show that falling fees of passive investing will increase market inefficiency, lower active fees by less than the passive fees, lower the fraction of active investors, and lower the number of active managers.

(In addition to the growth- and value-style funds, the table also shows how the company’s active large-blend funds have fared.) From this admittedly small sample size, there is no evidence of index-fund superiority. They have low long-term success rates, while penalties are high for picking a loser (per the negatively skewed distribution). One fund has an annual fee of 0.08%, and the other has an annual fee of 0.76%. If both returned 5% annually for 10 years, that lower-cost 0.08% fund would be worth about $16,165, whereas the 0.76% fund would be worth about $15,150, or about $1,015 less. And the difference would only compound over time, with the lower-cost fund worth about $3,187 more after 20 years.

Dividends are cash payments from companies to investors as a reward for owning the stock. Active investing requires analyzing an investment for price changes and returns. Familiarity with fundamental analysis, such as analyzing company financial statements, is also essential. But in certain niche markets, he adds, like emerging-market and small-company stocks, where assets are less liquid and fewer people are watching, it is possible for an active manager to spot diamonds in the rough.
A less natural implication of Assumption 2 is that securities with more correlated fundamentals have less correlated supply shocks (except in the special case, which overlaps with Assumption 1, when all securities are i.i.d.). Assumption 1 means that the model variables are driven by a standard factor model. We refer to the portfolio proportional to β as the “factor portfolio,” since this portfolio is maximally correlated with the common shocks. It is natural to think of this factor as the unconditional average market portfolio, q¯. The factor portfolio also could be different, but we normalize β so that β⊤q¯≥0. The model is, of course, richer, and provides both the fees and the market inefficiency as outcomes once the asset structure is fully specified and parameterized, which we do starting in the next section.
In addition, a further benchmark is applied independent of the four-index model to provide a broad range of results with different market returns. For this second benchmark, Kenneth R French’s Research Factors of excess market returns are identified from his infamous website. By applying two separately structured passive benchmarks, a broader opportunity to compare the returns is presented.
There is no guarantee that past performance or information relating to return, volatility, style reliability and other attributes will be predictive of future results. International investing entails greater risk, as well as greater potential rewards compared to U.S. investing. These risks include political and economic uncertainties of foreign countries as well as the risk of currency fluctuations. These risks are magnified in countries with emerging markets, since these countries may have relatively unstable governments and less established markets and economies.
While the Kullback-Leibler divergence is random (since it depends on the conditioning variables p and s), the proposition establishes that the expected Kullback-Leibler divergence also equals overall market inefficiency. Hence, this result establishes a new potential way to measure market efficiency and the economic value of information, namely, using entropy-based methods also applied in other sciences. The standard “APT of returns” says that risk premiums must be driven by systematic factors. The Active vs. passive investing economics behind the APT is that, if certain assets delivered abnormal returns relative to their factor loadings, then investors could earn a return with a risk that can be diversified away, and such near-arbitrage profits are ruled out in equilibrium. As in Ross (1976), the APT generally holds as an approximation, but having a fully specified equilibrium provides us with an explicit condition for it to hold exactly, namely, that every asset constitutes a vanishing part of the economy in the limit.
Furthermore, expenses and costs accounted for 0.65% of yearly returns at the beginning of the study in 1975 and increased to 0.99% in 1994. Malkiel (2003) also suggests that after costs active funds in general must underperform the market benchmark. Results of his study, which focuses on index investing and efficient markets, show that costs and expenses account for 1.2% of performance in average. Data in the study assumes a market return of 10%, and these 120 basis points attributed to expenses from active investing are the exact thresholds which lead to underperformance relative to the benchmark. Hence, a small proportion of active managers do indeed earn abnormal returns and therefore demand higher management fees, even though most academic researchers agree that investors are better off with passive indices than active funds simply due to outperformance. Hedge funds and private equity managers are one example, charging enormous fees (sometimes 10%, 15%, 20% of returns) for their investing acumen.
The study links portfolio managers’ beliefs, views and other parameters with the portfolios having the highest and lowest Sharpe ratios. Results suggest that active funds can be a higher performing alternative than passive indices when measuring https://www.xcritical.in/ performance with the Sharpe Ratio (Pástor & Stambaugh, 2002). Another trend over the past decades is the decline in the cost of passive management. These predictions are consistent with the empirical findings by Cremers et al. (2016).
