Picking from the multitude of style mutual funds is a daunting task. In any given style there may be as many as 954 different mutual funds, and there are at least 6125 mutual funds across all styles.

Why are there so many mutual funds? The answer is because mutual fund providers are making lots of money selling them. The number of mutual funds has little to do with serving investors’ best interests. Below are three red flags investors can use to avoid the worst mutual funds:

  1. Inadequate liquidity
  2. High fees
  3. Poor quality holdings

I address these red flags in order of difficulty. More details on the best & worst mutual funds by style are here.

How To Avoid Mutual Funds with Inadequate Liquidity

This is the easiest issue to avoid, and my advice is simple. Avoid all mutual funds with less than $100 million in assets. Low asset levels tend to mean lower volume in the mutual fund and larger bid-ask spreads.

How To Avoid High Fees                                                             

Mutual funds should be cheap, but not all of them are.

To ensure you are paying at or below average fees, invest only in mutual funds with total annual costs (TAC) below 2.40%, which is the average TAC of the 6730 U.S. equity mutual funds I cover. If you weight the TACs by assets under management, then the average TAC is lower at 1.52%. A lower weighted average is a good sign that investors are putting money in the cheaper mutual funds.

Figure 1 shows the most and least expensive style mutual funds in the U.S. equity universe based on total annual costs. John Hancock Funds provides the three most expensive style funds, while Vanguard provides four of the five cheapest Mutual Funds.

While costs among ETFs fall into a generally narrow range, mutual fund costs are more varied. The high costs of the most expensive mutual funds, sometimes above 8% annually, make it much harder for them to perform as well as the cheapest mutual funds.

However, investors need not pay high fees for good holdings. Sun America Focused Dividend Strategy Portfolio (FDSWX) is my number-one-rated style mutual fund overall, yet it has a low total annual cost of 0.92%.

On the other hand, the Vanguard Index Funds (VIIIX, VITPX, VINIX, VITSX) and the Fidelity Spartan 500 Index Fund (FXAIX) that make up the five cheapest funds in figure 1 all hold too many poor stocks, each getting a 3-star or Neutral rating. And no matter how cheap a mutual fund, if it holds bad stocks, its performance will be bad.

This result highlights why investors should not choose mutual funds based only on price. The quality of holdings matters more than price.

How To Avoid Mutual Funds with the Worst Holdings

This step is by far the hardest, but it is also the most importantbecause a mutual fund’s performance is determined more by its holdings than its costs. Figure 2 shows the mutual funds within each style with the worst holdings or portfolio management ratings. The styles are listed in descending order by overall rating as detailed in my 3Q13 Style Rankings report.

My overall ratings on mutual funds are based primarily on my stock ratings of their holdings. My firm covers over 3000 stocks and is known for the due diligence done on each stock we cover.

The 360 Funds by Snow Capital appear more often than any other providers in Figure 2, which means that they offer the most mutual funds with the worst holdings. All of the funds, with the exception of First Pacific Low Volatility Fund (LOVIX) and 360 Snow Capital Market Plus Fund (SPLIX), receive a 1-star or Very Dangerous rating overall. LOVIX and SPLIX both receive 2-star or Dangerous overall ratings.

Note that no mutual funds with a Dangerous portfolio management rating earn an overall rating better than two stars. These scores are consistent with my belief that the quality of a mutual fund is more about its holdings than its costs. If the mutual fund’s holdings are Dangerous, then the overall rating cannot be better than Dangerous because one cannot expect the performance of the fund to be any better than the performance of its holdings.

Still, while the Marketocracy Masters 100 Fund (MOFQX) and 360 Snow Capital Market Plus Fund (SFOIX) receive Dangerous portfolio ratings, their high annual costs of 3.95% and 1.28% respectively lower their overall ratings to Dangerous or 2-stars. Even mutual funds with more highly rated holdings must be considered Dangerous or Very Dangerous if their costs are too great.

The Danger Within

Buying a mutual fund without analyzing its holdings is like buying a stock without analyzing its business and finances. As Barron’s says, investors should know the Danger Within. Put another way, research on mutual fund holdings is necessary due diligence because a mutual fund’s performance is only as good as its holdings’ performance.

Best & Worst Stocks In These Mutual Funds

Tetra Technologies (TTI) is one of my least favorite stocks held by Roumell Opportunistic Value Fund (RAMSX) and earns my Dangerous rating. TTI’s profits (NOPAT) have fallen from $39 million in 2005 to $35 million in 2012. TTI’s return on invested capital (ROIC) is just 3%, which puts it in the bottom quintile of all companies I cover, and the firm had a free cash flow (FCF) yield of -20% last year. One would think investors would shy away from a firm that has shown this kind of long-term profit decline and low returns on its capital, but the market has high expectations for TTI, which is currently trading at ~$10/share. To justify this stock price, TTI would need to grow NOPAT by over 14% compounded annually for the next 15 years. Meetingthese expectations seems like a stretch for a firm that has seen profits decline over the last 7 years. Significant allocations to Dangerous-rated stocks like TTI result in RAMSX’s Very Dangerous portfolio management rating and Very Dangerous rating overall.

Chevron (CVX) is one of favorite holdings in the Vanguard Institutional Index Fund (VIIIX) and gets my Attractive rating. Chevron has grown profits (NOPAT) by an impressive 23% compounded annually since 1998 and has raised its return on invested capital (ROIC) from 4% to 11% over that time as well. Although these numbers show Chevron has strengthened its fundamentals and has the capability to grow profits dramatically, CVX is still trading at ~$126/share. This stock price gives CVX a price to economic book value ratio of 0.8, implying that the market expects Chevron’s profits to permanently decline by 20%. With Chevron’s notable record of long-term profit growth and rising ROIC, a permanent 20% decline in the company’s NOPAT seems unlikely. VIIIX’s allocation to Attractive stocks like CVX earn it the best rating of the funds in figure 1.
