Penny stocks, cryptocurrency, options contracts, private credit, and venture capital investments are all examples of high-risk investments. What makes them “high-risk” is a combination of sharp price swings, the real possibility of losing most or all of your money, and difficulty selling when you want out. Understanding what puts an investment in this category helps you recognize risk before you commit money to it.
Cryptocurrency
Crypto is one of the most widely cited high-risk investments today. Bitcoin, Ethereum, and smaller tokens can gain or lose 20% or more in a single week. Unlike a stock, which represents ownership in a company with revenue and assets, most cryptocurrencies derive their value almost entirely from market demand and speculation. There are no earnings reports, no dividends, and no underlying business to analyze.
The regulatory picture adds another layer of risk. Many crypto investments fall outside the protections that cover traditional brokerage accounts. If an exchange fails or your tokens are stolen, you may have no recourse through government-backed insurance programs. That doesn’t mean crypto can’t produce large returns, but the range of outcomes is enormous, from doubling your money to losing it entirely.
Penny Stocks
Penny stocks are shares of very small companies that typically trade below $5 per share, often on lesser-known exchanges rather than major ones like the NYSE or Nasdaq. These companies usually have little revenue, thin financial records, and minimal analyst coverage. That makes it hard to evaluate whether the stock is worth anything at all.
Liquidity is a major concern. Because so few shares trade on any given day, you might not be able to sell at the price you see quoted. A stock that jumped 40% on a rumor can drop just as fast, and if there aren’t enough buyers, you could be stuck holding shares worth far less than you paid. Penny stocks are also frequent targets of “pump and dump” schemes, where promoters inflate the price through misleading hype and sell their own shares before it crashes.
Options and Contracts for Difference
Options give you the right to buy or sell an asset at a set price before a specific date. If the price moves in your favor, the gains can be many times your initial investment. If it doesn’t, you can lose 100% of the money you put in, and the loss happens fast because options expire. Unlike owning a stock outright, where you can wait out a downturn, an option that expires worthless is gone.
Contracts for difference (CFDs) work similarly in terms of risk. A CFD lets you bet on the price movement of an asset without actually owning it, using borrowed money (leverage) to amplify gains and losses. If the trade moves against you, losses can exceed what you initially deposited. CFDs are banned for retail investors in the U.S. but available in many other countries, and they carry some of the highest loss rates of any retail investment product.
Private Credit and Private Equity
Private credit means lending money directly to companies outside the traditional banking system. These loans often go to mid-size businesses that can’t easily borrow from banks, and they pay higher interest rates to compensate for the added risk. But that higher return comes with real downsides.
There is essentially no secondary market for most private credit. If you invest through a fund, you should expect to hold until the loans mature or accept steep losses if you need to exit early. Default risk is meaningful: Federal Reserve research notes that the average recovery rate on defaulted private credit loans is around 33 cents on the dollar, compared to about 52 cents for traditional syndicated loans. Many of the borrowers operate in sectors like software and healthcare services where there are few hard assets to seize if the company fails.
Private equity, where you invest directly in companies that aren’t publicly traded, carries similar illiquidity. Your money is typically locked up for years, and the value of your investment depends on whether the fund manager can eventually sell those companies at a profit. Both private credit and private equity funds generally restrict access to accredited investors: individuals with a net worth above $1 million (excluding their primary residence) or income above $200,000 individually ($300,000 with a spouse) for the prior two years.
Venture Capital and Startup Investing
Putting money into early-stage startups is among the riskiest bets in investing. Most startups fail. Even professionally managed venture capital funds expect the majority of their portfolio companies to return little or nothing. The strategy depends on a small number of massive winners making up for all the losses, but individual investors rarely have the diversification to replicate that approach.
Your money is illiquid for years, there is no public market to sell your shares on, and the information available about the company’s finances is far less detailed than what you’d get from a publicly traded firm. Crowdfunding platforms have opened startup investing to non-accredited investors, but the underlying risk profile hasn’t changed.
What Makes an Investment “High-Risk”
Across all these examples, three traits show up repeatedly. First, volatility: the price can swing dramatically in short periods, meaning your investment could lose a large percentage of its value before you can react. Second, illiquidity: you may not be able to sell when you want to, or you’ll have to accept a painful discount to get out. Third, information gaps: with less transparency, fewer regulatory requirements, and thinner public records, it’s harder to know what you’re actually buying.
Leverage amplifies all three problems. Any time borrowed money is involved, whether through margin trading, options, or CFDs, the potential for loss grows beyond what you originally invested. A 10% drop in the underlying asset can wipe out your entire position, or worse, leave you owing money.
How High-Risk Fits Into a Portfolio
High-risk investments aren’t inherently bad. They exist because some investors are willing to accept a higher chance of loss in exchange for the possibility of outsized returns. The key distinction is how much of your money is exposed. Putting 5% of a diversified portfolio into a speculative position is very different from concentrating your savings in a single cryptocurrency or startup.
The practical test is straightforward: if this investment went to zero tomorrow, would it change your life? If the answer is yes, the position is too large relative to your financial situation, regardless of how promising the opportunity looks. High-risk investments reward patience, diversification, and a genuine ability to absorb losses without derailing your broader financial goals.
