As the financial technology industry continues to expand, new wealth management tools, budgeting platforms and investment vehicles like robo-advisors have democratized access to financial products and services. Micro-investing makes owning stock possible for everyone.

In the past, beginning investors without a lot of capital didn’t have many choices if they wanted to get a better return on their money than what a savings account provided. In the 1980s the average cost to place a stock trade was $45 (and could be a lot more if you had a “full-service” broker). Oftentimes, you had to have several thousand dollars minimum deposit before you could even open a brokerage account.

Even after online brokers dropped trading fees to under $10 per trade at the beginning of this decade, you can’t buy a single share of Amazon.com Inc. or Alphabet Inc. (parent of Google) unless you have a cool grand lying around. That’s why the invention of the “micro-investing” platform has been so good for the everyday saver.

Micro-Investing Gives You Stock Market Returns With Banking Simplicity

Micro-investing offers people a way to capitalize on superior returns offered by financial markets in a convenient and low-stress way.

Since 2010, several firms have opened that offer accounts with low- or no- minimum-deposit requirements and fractional investing where you can buy $5 of Amazon stock (if that’s what you’re into).

The best part is, in the long run, you’ll end up with much more money than if you put the same cash in the bank.

Even the best savings account returns only 2.5% per year, which means if you put in $1,000, you’ll earn $25. On the other hand, the Invesco QQQ ETF that tracks stocks on the tech-heavy Nasdaq returns nearly 20% on average, so your $1,000 gets you $200 by the end of the year. (Of course, stocks can go down as well as up, like when the Dotcom Bubble burst and the QQQ lost 80% of its value over 18 months. But in the long run, stocks have historically outperformed savings accounts.)

How Micro-Investing Works

Easy-to-download apps like Stash and Acorns typically leverage exchange-traded funds (ETFs), a diversified fund that trades like a stock on an exchange, and is comprised of a basket of securities that track an underlying index.

Most of the platforms below offer personalized portfolios based on an individual’s risk tolerance, which can be calculated by a series of questions regarding age, life plans, and aversion to taking a loss on your investment.

Some apps, like Robinhood, hook up to users’ bank accounts and allow them to transfer money on a one-time basis or as a recurring deposit. Other apps like Acorns automatically invest extra money in the form of spare change, syncing up with users’ debit or credit cards and taking the difference between the purchase price and the next full dollar amount to invest.

All that taken into consideration, micro-investing serves as a gateway to the stock market for individuals with little in savings or not much income. For those that remain skeptical of investing, who lack experience, or are just starting out, micro-investing serves as a simple way to start setting aside a small amount of money on a regular basis with minimal commitment.

Who Are Micro-investors (Hint: Millennials)

It’s no surprise then, that Millennials are behind the booming micro-investing space. As tech-savvy, commitment-averse Millennials seek to optimize and automate their financial lives, they have become the biggest users of trading apps and robo-advisors.

Millennials are set to overtake baby boomers in 2019 as the largest U.S. generational group, according to population projections from the U.S. Census Bureau. Soon Millennials’ choices about investing will set the standards as the industry strives to accommodate them, and they have demonstrated a preference for technology stocks, as well as growth stocks across “riskier” markets like the emerging marijuana industry.

As Millennials enter their prime investing and earnings years, the micro-investing industry is likely to maintain its momentum, and evolve with the trends. But micro-investing is for everyone, no matter how old you are. Just like it’s never too late to start saving for retirement, it’s never too late to learn fresh investing strategies from new generations.

What to Look for in a Micro-investing App

In light of the growing options available to those choosing a micro-investing platform, it’s important to look at a few differentiating factors to figure out what’s right for each individual investor.

What Micro-Investing Apps Cost

Look out for cost above all else. While some services offer no-fee trading and no-fee bank transfers, some may have hidden costs and fees. Additionally, while many platforms boast that they waive minimum account balances, others may require them.

Often the biggest fee is for assets under management. Some platforms charge a management fee for the amount of money in your account, so if you have $5,000 and they have a 0.25% management fee, you pay $12.50 per year.

Depending on what the app invests in, you might pay an additional fee. For example, mutual funds often charge fees, including management fees, that can eat into your returns. This is called the fund’s “expense ratio,” and the average expense ratio for a hybrid mutual fund that invests in stocks and other assets (like bonds or real estate) is 0.74% or $74 for every $1,000 you have invested.

ETFs also have expense ratios that average around 0.44%, according to the Wall Street Journal. And if you sell the assets in your account, depending on what type of account it is, you might be on the hook for capital gains taxes.

What Kind of Services You Get From Micro-Investing Apps

A key principle of investing, particularly for beginners, is portfolio diversification where funds are allocated across a wide range of investment opportunities to hedge against the risk that a single stock or even industry might get hit by a drop in price.

Most micro-investing apps achieve diversification by putting your money into mutual funds and ETFs. But some apps, like Robinhood which is primarily for trading stocks and ETFs, put the responsibility on you to keep your portfolio diversified.

Some apps allow for custodial accounts or accounts set up for minors. With these accounts, you can start saving for college or give shares as a gift for holidays or birthdays.

For those seeking financial insights and educational materials, not all apps are created the same. Some apps like Stash and Acorns have blogs with educational materials to help you understand the concepts behind how the apps work. Public.com has a transparent community to learn from. Robinhood’s help page also gives basics for investing in cryptocurrencies.
