## 💡 Why is the Materials ETF Ticker `XLB`? (ETF Ticker Etymology)
> [!note] The Origin of `XLB` and Sector Tickers
> When State Street Global Advisors launched the **Select Sector SPDR ETFs** in 1998, sector naming was based on earlier industry standards (such as Dow Jones / early MSCI definitions):
> - **`XLB` = Basic Materials**: The sector was originally called **"Basic Materials"**. Although GICS later shortened the sector name to **"Materials"**, the ticker **`XLB`** was kept to preserve liquidity and continuity.
> - **The "XL" Prefix**: Derived from "e**XL**usive," used across the entire SPDR sector suite as a standard prefix.
