NerdWallet's ratings for brokers and robo-advisors are weighted averages of several categories, including investment selection, customer support, account fees, account minimum, trading costs and more. Our survey of brokers and robo-advisors includes the largest U.S. providers by assets under management, plus notable and/or emerging players in the industry. Factors we consider, depending on the category, include advisory fees, branch access, user-facing technology, customer service and mobile features. The stars represent ratings from poor (one star) to excellent (five stars). Ratings are rounded to the nearest half-star. Is Stock Trading Easy?
Different investors are going to prioritize different things. A day trader, for example, requires speed and flexibility. A first-time trader may value educational resources and reliable customer support. But one thing every trader should care about is cost. Not paying attention to investment expenses is like revving your car engine while filling it with gas. That's why we spent a lot of time balancing price with what each site offered. What Is Stock Market Capitalization?
In margin buying, the trader borrows money (at interest) to buy a stock and hopes for it to rise. Most industrialized countries have regulations that require that if the borrowing is based on collateral from other stocks the trader owns outright, it can be a maximum of a certain percentage of those other stocks' value. In the United States, the margin requirements have been 50% for many years (that is, if you want to make a $1000 investment, you need to put up $500, and there is often a maintenance margin below the $500).
Think win/win. Psychology is a huge aspect of trading. If you have a big winner on your hands and aren’t sure whether you should hold the shares to try for higher prices or sell them to lock in a profit, consider selling half and holding the rest with a stop loss (at worst) back at your original buy price. That way, if the stock drops back to your buy price, you still win because you sold half and made a profit. Similarly, if the stock shoot higher in price, you also win because you still hold half your original position. Heads you win, tails you win too. 🙂
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.
