News sites such as CNBC and MarketWatch serve as a great resource for beginners. For in depth coverage, look no further than the Wall Street Journal and Bloomberg. By casually checking in on the stock market each day and reading headline stories, you will expose yourself to economic trends, third-party analysis, and general investing lingo. Pulling stock quotes on Yahoo Finance to view a stock chart, view news headlines, and check fundamental data can also serve as another quality source of exposure.
The main difference between ETFs and mutual funds is in how they trade. ETFs trade like stocks, which means you can buy and sell them throughout the day and they fluctuate in price depending on supply and demand. Contrarily, mutual funds are priced each day after the market closes, so everyone pays the same price. Also, mutual funds typically require a higher minimum investment than ETFs.
Financial innovation has brought many new financial instruments whose pay-offs or values depend on the prices of stocks. Some examples are exchange-traded funds (ETFs), stock index and stock options, equity swaps, single-stock futures, and stock index futures. These last two may be traded on futures exchanges (which are distinct from stock exchanges—their history traces back to commodity futures exchanges), or traded over-the-counter. As all of these products are only derived from stocks, they are sometimes considered to be traded in a (hypothetical) derivatives market, rather than the (hypothetical) stock market.
