Analyzing ETFs for Better Portfolio Performance

ETFs offer diversification benefits by allowing investors to spread their risk across various asset classes.

By investing in a broad-based ETF, you can gain exposure to a large number of stocks, bonds, or other securities with a single trade.

The expense ratio of an ETF is a significant factor to consider, as it can eat into your returns.

A low expense ratio can help you save money and potentially earn higher returns over time.

Some ETFs are designed to track a specific index, such as the S&P 500, while others focus on a particular sector or geographic region.

Understanding the underlying index or investment strategy of an ETF is crucial to making informed investment decisions.

Regularly monitoring your ETF holdings and rebalancing your portfolio as needed can help you stay on track with your investment goals.

Analyzing ETFs can be a complex task, but breaking it down into smaller parts makes it more manageable. First and foremost, you need to evaluate the ETF's tracking efficiency, which refers to how well it tracks the underlying index it's designed to track.

To do this, you can examine the "tracking error" and "tracking difference" statistics, which can be found in the article's example of 1-year performance between the SPY and the S&P 500 Index (SPX). If the ETF manages to pass this check, it's worth further evaluation.

You can also use APIs like FMP's to analyze ETF fund holdings and make informed investment decisions. For instance, the Bulk Ratings API provides detailed ratings for various securities, including those within ETFs, which helps investors understand the quality and risk profile of the underlying assets.

ETFs come in a variety of types, each with its own investment focus.

Stock ETFs focus on stocks and track the performance of specific indices, such as the S&P 500.

There are also Bond ETFs, which offer a more stable income by investing in a variety of bonds.

Commodity ETFs are centered around commodities like gold or oil.

Sector and Industry ETFs target specific industries, such as technology or healthcare.

International ETFs invest in foreign markets, offering exposure to global economies.

Here's a breakdown of the main types of ETFs:

Portfolio Measures are a crucial aspect of evaluating ETFs. You want to ensure that the ETF you're considering is a good fit for your investment goals and risk tolerance.

The price-to-earnings (P/E) ratio is a key metric to examine. It helps you understand whether an ETF is trading at a relatively cheap or expensive price compared to similar ETFs and the index benchmark.

A high P/E ratio might indicate that an ETF is overvalued, while a low P/E ratio could suggest it's undervalued. For example, if the P/E ratio of the SPY is significantly higher than that of its index benchmark, it may be a sign that it's overvalued.

The dividend yield percentage is another important value measure. It gives you an idea of whether you're receiving an appropriate amount of dividend income.

To make it easier to compare ETFs, Morningstar provides multiple value and growth measures, including P/E ratio, price-to-book (P/B) ratio, and dividend yield percentage. However, ETF.com simplifies this to just three measures: P/E, P/B, and dividend yield.

Here's a quick reference table to help you compare these measures:

By examining these measures, you can get a better understanding of an ETF's value and growth potential. If there's no substantial difference between the fund and its index and/or category, it may not be worth looking into further.

Expense ratios are a crucial factor to consider when analyzing ETFs. It's the annual amount deducted from an investor's account to cover the fund's expenses.

The expense ratio calculation is straightforward: it's the operating expenses divided by the average assets. This metric gives you a clear picture of how much an ETF is costing you.

A low expense ratio is essential for long-term investors. Even a small difference in expense ratios can add up over time, reducing your returns significantly. For example, a 0.50% expense ratio may not seem like a lot, but it can shave off a substantial amount from your investment.

ETFs with low expense ratios are generally more efficient and effective. They allow you to keep more of your investment returns, which is especially important for long-term growth.

Here's a rough guide to help you gauge the impact of expense ratios on your investments:

As you can see, the larger the expense ratio, the less efficient an ETF is from an investor's perspective. Always opt for the cheapest ETF available, especially when investing in niche markets.

If an ETF promises more expected returns or has a harder-to-access market, it may be worth paying a slightly higher expense ratio. However, I rarely buy ETFs with an expense ratio over 0.50%.

Tracking Difference is a crucial aspect of evaluating ETFs. It measures how far an ETF has lagged its benchmark, on average, over a one-year period. This statistic incorporates the effects of an entire range of management decisions, from securities lending to optimization decisions.

A lower tracking difference is better, as it indicates the ETF is more efficient and well-run. One favored measure of tracking difference is the standard deviation of returns between the ETF and its index. This is also known as "tracking error."

To calculate tracking error, you can use the formula: Tracking error = Standard deviation of (P - B), where P is the portfolio return and B is the benchmark return. This will give you a number that can be used to compare against other ETFs tracking the same index.

The lower the tracking error number, the better. A tracking error of 0.02, for example, is negligible. You can also use Excel to calculate r-square, beta, and standard error, which can indicate how well a particular ETF tracks its benchmark index.

Here are some general guidelines for evaluating tracking difference:

Remember, a lower tracking difference is better, as it indicates the ETF is more efficient and well-run.

Analyzing the portfolio composition of an ETF is crucial to understanding if it's providing the exposure you're looking for. This can be accomplished by examining the portfolio sector/industry breakdown, portfolio concentration, and security market cap allocations.

A good place to start is by evaluating the sector/industry breakdown within the ETF's portfolio, and comparing it to funds tracking the same index, and the index benchmark itself. This will also help you assess risk, given that you're familiar with your risk tolerance, the current and future market outlook, and how different industries/sectors are performing or expected to perform.

You can use ETF.com to look under the "Fit" tab for a particular ETF page, where you'll see the ETF's portfolio sector/industry breakdown. This will also show you where the securities in the portfolio originate from, which is relevant for ETFs providing international exposure.

For example, the SPY sector/industry breakdown compared to its index benchmark is below:

As you can see, the sector/industry breakdown for the SPY is quite different from its index benchmark. You should evaluate whether this sector/industry breakdown fits the amount of exposure you're looking for, and whether the differences are significant.

Another important area to evaluate is portfolio concentration. Funds with concentrated holdings are more closely tied to the performance of the shares they own. You should ensure that the weightings of an ETF's top securities (i.e., 10 or 15 securities) are not too high or too low, based on comparable ETFs tracking the same index.

ETF Database has a "Concentration Analysis" portion of their website that can help you answer most of your questions around portfolio concentration and size. This can also be seen on ETF.com under the "Fit" tab on an ETF's page.

In general, I look closer into any ETF portfolio concentration above 30-40%, although this may vary depending on the industry. If there appears to be a substantial difference in weightings, then this is likely due to the ETF's strategy, as outlined in its prospectus document.

Tax efficiency is a crucial aspect of ETF analysis. The management fee, for example, can eat into your returns. A lower fee of 0.05% can save you $50 per year on a $100,000 investment.

Tax efficiency is also influenced by the turnover rate, which is the rate at which an ETF's holdings are sold and replaced. A higher turnover rate can lead to more capital gains distributions and a larger tax bill. For instance, an ETF with a 100% turnover rate will have a higher tax liability than one with a 10% turnover rate.

Tax-loss harvesting is a strategy that involves selling securities that have declined in value to offset gains from other investments. This can help reduce your tax bill and increase your after-tax returns. By implementing tax-loss harvesting, you can potentially save hundreds or even thousands of dollars in taxes each year.

The Bulk Ratings API is a powerful tool for ETF analysis. It provides detailed ratings for various securities, including those within ETFs.

This data helps investors understand the quality and risk profile of the underlying assets. By using the Bulk Ratings API, investors can evaluate the credit ratings of bonds or other securities within an ETF.

For example, if an ETF holds bonds with high credit ratings, it may indicate lower credit risk, which is valuable for risk-averse investors.

Here's a breakdown of how the Bulk Ratings API can help:
