If investing in single stocks may be too risky for you, consider investing in good growth stock mutual funds. Mutual funds are a simple, even boring, investment plan, yet they work well for most people. Of course, all investing requires a degree of risk; there really is no sure thing. But mutual funds are a great balance of reasonable risk and excellent returns. They have built-in diversification that will keep you from putting all your eggs in one basket.

In that case, it is possible to invest passively in capital markets. This means that a private investor puts aside either a lump sum or an amount each month and the money is invested into a fund. That fund contains the savings of lots of other private investors and is managed by a professional equities investor. The fund will then be invested in an equity market (such as the NYSE) or a sector (such as energy).
Rarely is short-term noise (blaring headlines, temporary price fluctuations) relevant to how a well-chosen company performs over the long term. It’s how investors react to the noise that really matters. Here’s where that rational voice from calmer times — your investing journal — can serve as a guide to sticking it out during the inevitable ups and downs that come with investing in stocks.
For the active trader, execution speed and fill price are very important.

For the majority of investors, saving a penny per share on a 100 shares order isn’t the end of the world, but for active traders it is something to look into. To understand Order Execution, read this guide.
Note that once a broker has identified you as a pattern day trader due to the above activity, your account will likely be considered a pattern day trading account going forward, even if you don’t continue to meet the definition. If you decide to stop day trading, you’ll want to contact your brokerage and ask that they remove the minimum equity requirement from your account.
