Foreign. Hi, I'm Andy Tempte and welcome to Money Lessons. Join me every Saturday morning for bite sized lessons that are designed to improve financial literacy around the world. Today is November 29, 2025. Last week we discovered how mutual funds and index funds democratized equity investing by solving the diversification challeng. The 1940 Investment Company act created the regulatory framework, and Jack Bogle's 1976 Index Fund Innovation proved that ordinary investors could capture market returns at minimal cost. But mutual funds still required calling brokers and waiting days for transactions to clear. Today, we're exploring how technology completed our democratization journey, transforming stock ownership from an exclusive privilege into something anyone with a smartphone can do in seconds. So picture the New York stock exchange in 1970. Traders in colored jackets crowd the trading floor, shouting orders and scribbling on paper slips. The system works, but it's expensive, slow, and it requires physical presence. In February of 1971, NASDAQ launched the national association of securities Dealers Automated Quotation System, and it was the world's first fully electronic stock market. Unlike the New York Stock Exchange, with its physical trading floor, Nasdaq was purely electronic. Dealers connected through computer terminals, trading without anyone one shouting across a crowded room. Nasdaq proved that stock markets didn't need physical locations. Electronic systems could match buyers and sellers efficiently, transparently, and at a lower cost. But individual investors still faced a major obstacle, which was cost. Until 1975, the SEC required brokers to charge for fixed commissions, which were often $100 or more per trade. Such high fees made frequent trading or building diversified portfolios prohibitively expensive for most Americans. In May of 1975, the securities and Exchange Commission eliminated fixed commissions. Competition could now drive prices down. Within months, Charles Schwab launched his Discount Brokera, offering trades for a fraction of traditional costs. What had cost $100 would now cost only $29. Remember our compound interest series? High costs destroy returns over time. Reducing trading costs from $100 apiece to $29 a trade meant that middle class investors could build diversified portfolios without fees of their prospective gains. Traditional brokers initially dismissed discount brokerages, claiming that investors needed professional advice. But many investors, especially those buying index funds, simply needed inexpensive execution. Schwab proved that a massive market existed for low cost no advice brokerage Services now the 1990s brought another revolution. Online trading. E Trade launched in 1992, followed quickly by Ameritrade. Now investors could trade from home computers without calling brokers or visiting offices. Commissions dropped Even further, to $20 a trade, then $10 a trade account access became 24. 7. The barrier between investors and the markets was disappearing before our eyes. This accessibility, however, had consequences. The late 1990s saw explosive growth in what's called day trading, where people literally quit their jobs to trade stocks full time from home. Oh, by the way, not recommended. Internet and technology companies. Stocks soared to unsustainable valuation as investors rushed to capitalize on the prospect of the new Internet economy that was forming all around us, creating what became known as the dot com bubble. Online trading made this speculation easy and widespread. When the dot com bubble burst in the early 2000s, technology stocks lost trillions in value. Many inexperienced traders who had quit their day jobs to day trade lost their entire savings, learning painful lessons about the difference between investing and speculation. Now, by 2013, smartphones had become ubiquitous in society. A new brokerage called Robinhood launched with a radical idea. Zero commissions, no fees whatsoever for stock trades. The industry dismissed this as impossible. Are you seeing a trend here? Whenever there's an innovation, there's loads of people that are saying, oh, that's just nuts. We'll see that over and over again. How could brokerages survive without commission revenue? Well, Robinhood's answer was that they sold their customer orders to market makers, the financial intermediaries that actually execute trades. These intermediaries paid Robinhood for access to customer order flow, making their profits from the trading process itself, where you're just picking up pennies here and there. We'll explore how this works in future episodes. But the point is that commission free trading had arrived. Within five years, every major brokerage had eliminated commissions. Schwab, Fidelity, TG Ameritrade, all dropped to zero. By 2019, the cost barrier to investing had completely disappeared. Robinhood and their competitors added another innovation called fractional shares. Previously, if a stock cost a thousand dollars per share, you needed a thousand dollars. Fractional shares let you buy $10 worth of that same stock, owning only.01 of a share. Remember our latte example from that compound interest series? Investing $5 daily is now literally possible through smartphone apps like Robinhood offering fractional shares. So let's step back and see how far we've traveled through this series on equity securities. The Roman publicani in 200 BCE required normous amounts of wealth to participate in investing in state contracts. Next, the Dutch East India Company in 1602 needed substantial capital for even modest stakes in the company. Railroad stocks in the 1850s brought ownership to the middle class, but required hundreds of dollars and brokerage relationships. And then mutual funds in the 1900s enabled diversification for ordinary savers, but still involved loads of paperwork and intermediaries. Today, anyone with a smartphone and as little as $1 can own fractional shares of the world's largest companies, hold diversified index funds, and build wealth through compound growth. Our 2,200year journey from exclusive privilege to universal access is now complete. The technology exists. The costs have vanished. The barriers have fallen. Stock ownership is now more accessible than at any point in human history. But here's what we have to understand. Accessibility doesn't equal wisdom. The same smartphone app that lets you build wealth through disciplined index fund investing also lets you gamble on speculation or follow social media hype into disastrous losses. The democratization of investing is complete, but now comes the hard work financial education Understanding compound interest Recognizing the power of diversification Distinguishing investment from speculation Controlling emotions during periods of high market volatility Making decisions based on long term goals rather than short term price movements. This is why financial literacy matters so deeply and why this show is so important. The tools for building wealth are now in everyone's hands. Whether those tools build fortune or destroy it depends entirely on the knowledge and the discipline that we humans bring to using them. The future of belongs to the educated investor. The technology has done its job. Now we have to do ours. So until next week, I wish you grace, dignity and compassion. My name is Andy Tempte. This is Money Lessons.
