Investing involves risk

All investing involves risk, including the possible loss of all the money you put in. Prices of stocks, bonds, and funds go up and down, sometimes sharply and quickly. There is no guarantee of any return.

Stocks

Stock prices can fall because of company news, industry problems, the economy, or market mood. A company can fail, and its stock can become worthless.

Bonds and interest rate risk

Bond prices usually fall when interest rates rise. Longer-term bonds and bond funds tend to fall more. Bonds also carry credit risk (the borrower may not pay) and inflation risk (rising prices reduce what your interest can buy). Bond funds have no fixed maturity date, so their prices can stay down for a long time.

Exchange-traded funds (ETFs)

An ETF carries the risks of everything it holds. ETFs charge fees, can trade at prices slightly above or below the value of what they hold, and may have wide bid-ask spreads when trading is light. Narrow or specialty ETFs can be much riskier than broad ones.

Concentration

Putting a large share of your money in one stock, industry, or fund increases risk. Diversification can lower, but never remove, the risk of loss.

Limits of hypothetical results

All results in the App are hypothetical. They come from simulated trades with fake money, filled at assumed prices. They do not include every real-world cost, delay, or constraint, and they do not show how any real account would perform.

Hypothetical results from simulated trading with fake money; they have built-in limits and do not show what real trading would earn.

Copying trades by hand

If you copy a trade yourself, your price and timing will differ from the bot's paper fill. Prices can move between when a plan appears and when you act (this is called slippage). You may also face bid-ask spreads, fees, taxes, and settlement rules like T+1 and good-faith violations, which the App does not simulate.

Fractional shares

Whether you can buy fractional shares, and for which stocks or funds, depends on your broker. Some brokers don't offer them, some offer them only for certain securities, and rules for selling or transferring them vary.

AI and data risk

The bots' plans are shaped by AI models that can be wrong or make things up. No AI has a proven trading edge. Data feeds may be delayed, incomplete, or incorrect.
