With TradeUp, you can invest in stocks, ETFs, and options. You also have the ability to trade on margin. There are two main ways to make money with stocks:

1. Dividends. When publicly owned companies are profitable, they can choose to distribute some of those earnings to shareholders by paying a dividend. You can either take the dividends in cash or reinvest them to purchase more shares in the company.
2. Capital gains. Stocks are bought and sold constantly throughout each trading day, and their prices change all the time. When a stock price goes higher than what you paid to buy it, you can sell your shares at a profit. These profits are known as capital gains. In contrast, if you sell your stock for a lower price than you paid to buy it, you have incurred a capital loss.

The performance of an individual stock is also affected by what's happening in the stock market in general, which is in turn affected by the economy as a whole.

TradeUp offers commission free trading and no management fee.  They likely make money in several different ways:

1. Rebates from market makers and trading venues: Market makers (typically big institutions/funds) buy directly through the brokers to have discounted purchases. For that ability, the market makers pay a rebate to the brokerage to receive their orders . The brokerage sends your orders to the market maker that is most likely to execute at the best price for you and makes a few cents on each trade.
2. Income generated from cash: They borrow the cash sitting in your account and invest it into interest earning accounts and keep the profit.
3. Margin Lending: They collect interest on money they lend to investors.
4. Stock loan income from counterparties: They receive interest for loaning out shares for short sales.
