Money has been flowing from actively managed funds to low-cost passive investments like exchange-traded funds.Active managers have struggled for performance, but that couldbe about to change.An improvement in performance could, eventually, set the flow of money into reverse.NEW YORK - Investors have been enjoying one of the longest bull marketssince the 1940s. Markets are at all times highs, the S&P has tripled since the financial crisis and the Dow is close to hitting the landmark number of 20k. Investors in low-cost exchange-traded funds are riding the wave. As the indices go up, so do their investments.Meanwhile, active managers,whomake a living trying to beat the index, arestruggling,delivering underwhelming returns.That could be about to change.Active management is strugglingA combination of trends, including lacklusteractive management performance, regulation, and increasing cost consciousness, has led investors to move awayfrom actively managed funds and into passive productsthat track an index.Exchange-traded funds have gone from $230 billion in assets to around $4 trillionover the past 10 years.Vanguard calculatedthat82% of actively managed stock funds have either underperformed their benchmarks or shut down over the decade ended December 31, 2015.High costs are thebiggest reason active management has lagged, Bill McNabb,CEO atVanguard, saidin a blog poston January 10."Active management performance after fees continues to underwhelm," Moody's Vice PresidentNeal M. Epstein said. "Investors are remaining cost-conscious as skepticism of activemanagement's value proposition increases."Furthermore, global regulation is adding to fee pressures.The Department of Labor fiduciary rule taking effect in April 2017 requires advisors to show that their recommendations are aligned with their clients' interests. In the European Union, MiFid II is also trying to increase investor protection via regulatory oversight.Meanwhile, money continues to flow into passive investment products that trackthe market. Competition between ETF providers is leading to lower and lower costs. ETFs are also building momentum in newer asset classes like fixed income, emerging market equities and in new channels like retirement.The massive rotation from active to passive led Moody's to downgrade the global asset management industrylast December to "negative" from a "stable" rating.A reversal in 2017'Despite the trend, 2017 could just see areturn to form for the active management industry.Global markets have so far weathered surprise vote results in the UK and the US, but there is still a great amount of uncertainty over how Brexit will be managed, how president-elect Donald Trump's policies will play out, and how key European electionswill impactEurope.Add in a rate hike cycle, and 2017could see a "nirvana for active managers,"according to Morgan Stanley.Jefferies Group CEORich Handler echoed this sentiment. He told Business Insider he thinks we're atthe beginning of a slow increase in interest rates, saying that that will contribute to the return of stock pickers."This will slowly replace the market movements that have been dominated by macro trends forcing the mass buying and selling of baskets of securities," he said.According to Morgan Stanley's note,the post-crisis era has seenhigher correlation and lower dispersion in stocks. Correlation measures how two securities move in relation to each other, while dispersion measures the average difference between the return of an index and the return of each of the indexs components.However, the teamis now seeinggreater variability among stock returns. Unexpected consequences of Trump administration policies could lead to higher dispersion and lower correlation, potentially reaching levels not seen since the financial crisis, the bank said.This, ultimately, could create more opportunity for stock pickers to generate alpha and lead toactive management outperformance in 2017, according to the note.A number of sectors are up since the election on the possibility of Trump's campaign promises becoming reality.Potential tax reform and regulatory changes will benefit certain sectors, while the goal of bringing business investments and jobs back to the US could create a headwind for importers and companies that outsource manufacturing abroad. Whatever happens, there will be winners and losers."Significant uncertainty remains about what policy changes will be implemented over the next four years," according to the team led by equity analyst Michael J. Cyprys. "It could make 2017 a stock pickers' paradise."The general idea here is that active managers have a better chance to delivering index-beating returns in tougher, more complex markets.Astudy conducted by Thrivent Mutual Fundslast December found that index funds offer no assurance of outperforming actively-managed funds if a bear market ensues. The study shows that during the two market crashes of the 21st century, the S&P 500 and the Russell 2000 indexes significantly trailed their corresponding categories of actively-managed no-load mutual funds.Seth Masters, the chief investment officer ofBernstein Private Wealth Management,said we could be reaching "the inflection point" where active managers start to outperform index funds."We think that active investors that have good research and strong discipline will be able to generate very strong returns over the next few years compared to broad indices."SEE ALSO:The chief investment officer of a $490 billion fund manager on Trump, Dow 20K, and big dataJoin the conversation about this storyNOW WATCH: Here's why airlines make you put your phone on 'Airplane Mode
