Finally, the other factor: risk tolerance. The stock market goes up and down, and if you’re prone to panicking when it does the latter, you’re better off investing slightly more conservatively, with a lighter allocation to stocks. Not sure? We have a risk tolerance quiz — and more information about how to make this decision — in our article about what to invest in.

(Yale School of Forestry and Environmental Studies, chapter 1, pp. 18–43). As Goetzmann & Rouwenhorst (2008) noted, "The 17th and 18th centuries in the Netherlands were a remarkable time for finance. Many of the financial products or instruments that we see today emerged during a relatively short period. In particular, merchants and bankers developed what we would today call securitization. Mutual funds and various other forms of structured finance that still exist today emerged in the 17th and 18th centuries in Holland."
The rise of the institutional investor has brought with it some improvements in market operations. There has been a gradual tendency for "fixed" (and exorbitant) fees being reduced for all investors, partly from falling administration costs but also assisted by large institutions challenging brokers' oligopolistic approach to setting standardized fees. A current trend in stock market investments includes the decrease in fees due to computerized asset management termed robo-advisors within the industry. Automation has decreased portfolio management costs by lowering the cost associated with investing as a whole.
Replica of an East Indiaman of the Dutch East India Company/United East Indies Company (VOC). The Dutch East India Company was the first corporation to be ever actually listed on an official stock exchange. In 1611, the world's first stock exchange (in its modern sense) was launched by the VOC in Amsterdam. In Robert Shiller's own words, the VOC was "the first real important stock" in the history of finance.
For the majority, online trading (especially day trading) will not outperform simply buying the entire market, such as the S&P 500, and holding it for many years. Warren Buffett, the greatest investor of all-time, recommends individual investors simply passively invest (buy and hold) instead of trying to beat the market trading stocks on their own.

Regulation of margin requirements (by the Federal Reserve) was implemented after the Crash of 1929. Before that, speculators typically only needed to put up as little as 10 percent (or even less) of the total investment represented by the stocks purchased. Other rules may include the prohibition of free-riding: putting in an order to buy stocks without paying initially (there is normally a three-day grace period for delivery of the stock), but then selling them (before the three-days are up) and using part of the proceeds to make the original payment (assuming that the value of the stocks has not declined in the interim).
