High-Return Stocks: What Chasing Gains Costs
By Matthew Zimmerman — Director, Derivatives & Hedging Solutions · Published November 7, 2026 · 7 min read
High-return stocks are shares that have risen much faster than the market, but nearly every list of them is drawn up after the fact, from companies that already won. Chasing them means accepting concentration in a few names, deep falls along the way, and the real chance that the next decade's winners are different companies. The gains are visible in hindsight; the costs are paid in advance.
This post explains what "high return" means, why past winners look easier to pick than they were, and what concentration and leverage cost. It uses one of our own strategies as a worked example of how hindsight can flatter a result. It does not name stocks to buy.
What does "high return" actually mean?
A return is the change in value of an investment over a period, including any dividends. Two details make a big difference to how impressive a number looks.
The window. A stock that doubled from the bottom of a crash looks like a high-return stock. Measured from the peak before the crash, the same stock may have barely moved. Start and end dates can turn an average investment into a spectacular one, or the reverse.
The form of the number. A total return of 500% over 15 years and a yearly return of about 12.7% describe the same outcome. Total returns sound bigger, which is why adverts tend to use them. Our post on CAGR vs total return explains how to convert between the two.
A third detail is the path. A stock that rose 30% a year on average but fell 60% along the way is a very different holding from one that rose steadily. Most people only find out which kind they can live with when the fall arrives.
Why do past winners look so obvious?
Two biases make high-return stocks seem predictable when they were not.
Hindsight bias is the feeling that an outcome was obvious once you know it. Looking back, it seems clear that certain chip makers or online retailers would dominate. At the time, they sat alongside dozens of competitors with equally convincing stories, many of which faded or failed.
Survivorship bias comes from looking only at what is still around. Today's stock indexes contain the companies that grew large enough to be included. The ones that shrank, were taken over cheaply or went bankrupt have dropped out, so a list of today's leaders quietly excludes yesterday's failures. Over long periods, a relatively small number of companies have accounted for a large share of the stock market's total gains, while many listed companies did worse than the index or disappeared altogether.
Put the two together and you get the most common trap in stock picking: building a list of high-return stocks from today's winners and assuming the same approach would have found them in advance. We cover both biases in more depth in hindsight and survivorship bias.
What does concentration cost?
Holding a handful of stocks instead of a broad fund changes the shape of the risk, not just its size.
A broad index fund spreads money across hundreds of companies, so one company's collapse is a small dent. A portfolio of three or four stocks has no such cushion. If one holding falls 70%, which happens to well-known companies more often than people expect, a quarter or a third of the portfolio takes that hit.
The maths of recovery makes deep falls expensive:
| Fall from peak | Gain needed to get back |
|---|---|
| 25% | 33% |
| 50% | 100% |
| 70% | 233% |
| 90% | 900% |
Here is a simple illustration with made-up numbers. Two investors each put $10,000 into three stocks. Investor A splits it evenly. Investor B puts $8,000 in the stock they feel most sure about. If that stock falls 60% and the other two are flat, Investor A loses $2,000, or 20% of the total. Investor B loses $4,800, or 48%, and needs a gain of more than 90% just to get back to $10,000. Conviction does not change the arithmetic.
Concentration also brings timing risk. Even companies that eventually became huge winners went through falls of half or more on the way, and many investors sold during those falls. Owning a future winner and holding it through its worst years are two separate achievements.
A worked example: our own Big Tech Trend
The clearest way to see hindsight at work is in a backtest built on stocks that are famous today. Our Big Tech Trend strategy decides each month whether the market is healthy. In a healthy market it holds the strongest technology stocks and funds; in a weak one it moves toward short-term bonds, gold and defensive sectors.
In a historical backtest (a computer test on past prices) from January 2011 to November 2026, Big Tech Trend returned +37.3% a year with a worst fall of 29%. Over the same period the S&P 500 (SPY) returned +14.0% a year with a worst fall of 34%, and the Nasdaq 100 (QQQ) returned +18.3% a year with a worst fall of 35%. Its deepest fall in that period ran from June 22 to October 30, 2026, and it had not yet recovered when the test ended.
Nobody earned those returns, and future results will differ. The caveat is the point of this example: the stock list was chosen with hindsight, and three stocks made 81% of the profit.
Read those two facts together. The strategy could only hold names that were on its list, and the list was drawn up by people who already knew which technology companies had become giants. Then, within that list, most of the profit came from just three names. A test that started with a list of promising tech companies as they looked in 2010 would almost certainly have included some that went nowhere, and the result would have been weaker.
That is not unique to this strategy. Our Steady Growth strategy carries a similar warning: its seven names were picked because they already did well, which flatters the test. Any backtest or "top stocks" chart built from today's winners has the same flaw, whether or not it says so. We think it is better to say so. More on how this strategy works is in Big Tech momentum with a market filter.
Are leveraged funds a shortcut to high returns?
Leveraged ETFs are often marketed, or at least discussed, as a way to get high returns without picking stocks. A fund such as TQQQ aims for three times the Nasdaq 100's move for a single day. In a steady rising market it can return more than three times the index over that stretch. In choppy or falling markets the daily reset works against it, and losses compound quickly. In the 2022 rate-hike bear market, TQQQ lost most of its value. Our guides to TQQQ and leveraged ETF decay explain the mechanics.
Rules can reduce time spent in leveraged funds during bad markets, but they cannot remove the risk. Our Leveraged Growth strategy rotates between leveraged growth funds, volatility funds and bonds. In a historical backtest from January 2011 to November 2026 it returned +129.1% a year, against +13.9% for the S&P 500 and +18.2% for the Nasdaq 100. Its worst fall was 53%, deeper than the S&P 500's 34% and the Nasdaq 100's 35%, and it came within a month in the Covid crash of 2020, recovering about 3 months after the bottom. In a simulated three-fund version run through the 2000-2002 dot-com crash, it fell 91% against 47% for the S&P 500, and took 115 months to recover against 78 months.
Those are simulated results that nobody earned, and future results will differ. Its caveat: its rules may be fitted to the years after 2010, and leveraged funds can lose value quickly. A return figure that large is mainly a sign of how sensitive leveraged backtests are to the period chosen, not a guide to what an account could expect.
How can you judge a high-return claim?
When you see a stock, fund or strategy described as high return, a few questions cut through most of the noise:
- Over what dates? Check whether the period starts just after a crash or ends just before one.
- Compared with what? A tech-heavy result should be compared with the Nasdaq 100, not just a broad index.
- What was the worst fall, and how long did recovery take? A return without a drawdown is half the story.
- How was the list chosen? If the names were picked knowing how they turned out, the result is flattered.
- How much came from a few holdings? If most of the gain came from one or two names, the result depends on repeating that luck.
- What would you have done at the bottom? Be honest about whether you would have held on.

Key takeaways
- "High return" depends heavily on the dates chosen and on whether it is quoted as a total or yearly figure.
- Lists of high-return stocks are built with hindsight and survivorship bias; the winners looked far less certain at the time.
- Concentrating in a few stocks means deeper falls, and big losses need much bigger gains to recover.
- Our Big Tech Trend backtest shows the effect openly: its stock list was chosen with hindsight and three stocks made 81% of the profit.
- Leveraged funds such as TQQQ can amplify gains in calm markets but can lose most of their value in long declines.
