Today was a bad day for Wall Street: The Dow Jones dropped more than 4 percent by the end of the day, the biggest loss since 9/11 rocked the market in 2001.

On days like these, existing investors might really be smarting by the end of the day, feeling their losses — but newbies can capitalize on the downed market if they act quickly, by buying while the stocks are low and then seeing a return on their investment almost immediately.

I know this much about the stock market — that it usually averages itself out.  When the market is down, people start buying up stocks, which then shoots the market back up again.  So in other words, the impact of today’s bad day won’t last long.  However, there are a lot of things I don’t know about the stock market and Wall Street — for instance, I have no clue what E-mini futures trading is, let alone managed forex trading.  But websites such as Netpicks offer a good way to both learn about day trading and explore your options.

Wall Street offers excellent opportunities for people from all walks of life to invest.  Sure, there are bad days, like today, but on average people are able to increase their savings — otherwise, who would invest?  Whether you are looking for a long-term account with more conservative interest rates, such as a 401(k) or another type of retirement plan, or whether you are brave enough to enter the world of day trading, the stock market has something for you!
