Investing involves risks, including the risk of loss of principal. Market risk may affect a single issuer, sector of the economy, industry or the market as a whole. The fund is passively managed and seeks to track the performance of an index. There is no guarantee that the index and, correspondingly, the fund will achieve positive returns. Risk exists that the index provider may not follow its methodology for index construction. Errors may result in a negative fund performance. The fund's net asset value will generally decline when the market value of its targeted index declines. The fund concentrates its investments in issuers of one or more particular industries to the same extent as the underlying index. Investments in a narrowly focused sector may exhibit higher volatility than investments with a broader focus. Investments selected using quantitative methods may perform differently from the market as a whole and may not enable the fund to achieve its objective. Investment in larger companies may involve certain risks associated with their larger size and may be less able to respond quickly to new competitive challenges than smaller competitors. Investments in mid-cap companies often involve greater risks than investments in larger companies and may have less predictable earnings and be less liquid than the securities of larger firms. Growth securities, at times, may not perform as well as value securities or the stock market in general and may be out of favor with investors. Value securities may be unprofitable if the market fails to recognize their intrinsic worth or the portfolio manager misgauges that worth. Although the fund's shares are listed on an exchange, there can be no assurance that an active, liquid or otherwise orderly trading market for shares will be established or maintained. The Fund may have portfolio turnover, which may cause an adverse cost impact. There may be additional portfolio turnover risk as active market trading of the fund's shares may cause more frequent creation or redemption activities that could, in certain circumstances, increase the number of portfolio transactions as well as tracking error to the Index, and high levels of transactions increase brokerage and other transaction costs and may result in increased taxable capital gains.

ETF shares are bought and sold at market price (not NAV) and are not individually redeemable. Investors buy and sell shares on a secondary market. Shares may trade at a premium or discount to the NAV. Only market makers or "authorized participants" may trade directly with the Fund(s), typically in blocks of 50,000 shares.

Shares are not FDIC insured, may lose value, and have no bank guarantee.

How to read this report

Each ratio (e.g. XLU/SPY, Lumber/Gold) is a relative-performance signal — one asset priced against another. When the numerator wins, the ratio rises; when the denominator wins, it falls.

To size how unusual any given move is, we score each ratio's one-month return against its own three-year history using a standardized score (Z-score, shown as “σ”). Think of σ as “how many standard deviations from normal this reading is.” The labels attached to each level are:

• Background (|σ| < 0.5) — no meaningful signal, statistical noise
• Weak (0.5 ≤ |σ| < 1.0) — mildly above/below trend, a soft signal
• Notable (1.0 ≤ |σ| < 1.5) — clearly above/below trend, meaningful
• Significant (1.5 ≤ |σ| < 2.0) — a strong signal, roughly a once-every-three-months move
• Extreme (|σ| ≥ 2.0) — a rare move, roughly a once-a-year event or bigger

A ratio at -2.16 Z-score Extreme means the denominator has crushed the numerator on a scale we've only seen a handful of times in three years. That's the Lumber/Gold reading this week — and it's the reason the whole report leads with it.
