Dow Jones Transportation Average

The VIX, often called the 'fear gauge', measures the market's expectation of 30-day forward-looking volatility implied from S&P 500 options prices. It is not a traditional stock index but rather a real-time sentiment indicator used by traders to gauge market fear and complacency.

The Russell 2000 Index measures the performance of approximately 2,000 smallest companies in the Russell 3000 Index. It is the most widely followed benchmark for US small-cap stocks and is closely watched as a gauge of the domestic economy since small-caps tend to be more domestically focused.

The Dow Jones Industrial Average (DJIA) is one of the oldest and most recognised stock market indices in the world. It tracks 30 large, publicly owned blue-chip companies trading on the NYSE and NASDAQ. Despite its small constituent count, the Dow remains a cultural touchstone for the overall health of the US stock market.

The NASDAQ 100 tracks the 100 largest non-financial companies listed on the NASDAQ exchange. It is one of the premier large-cap growth indices, dominated by technology, consumer services, and healthcare names. The QQQ ETF tracks this index and is among the most liquid ETFs globally.
