Dips Like These Don’t Come Often - Should You Double Down?

Some of the most closely watched growth stocks have swung wildly over the past month. A few have surged, others have dropped hard, and investors holding them face a familiar question: which positions are worth holding, which deserve more money, and which should be trimmed?

The past month’s numbers show why the question is pressing. Of the seven investments covered here, five are down, including one that has fallen more than 25% and another that dropped about 10% in a single session after earnings. Of the two that rose, one has just hit an all-time high and the other jumped 13% in a day after its report. Some of these names look like buying opportunities. Others are starting to look worrying.

None of this shows up in the S&P 500, which is trading near its all-time high. The riskiest parts of the market, however, have been hit far harder, a reminder that the risk inside a portfolio matters as much as the market’s overall direction.

Three Forces Weighing on the Market

Inflation. September inflation came in hotter than expected. After raising rates in September, the Fed held steady on October 28, although two officials wanted another increase. With 10-year Treasury yields hovering near 5%, markets may still expect another hike by December.

AI spending. Demand for AI is booming, but investors are asking who will finance the massive data centers it requires. Gartner has warned that more than 80% of neocloud providers, the companies that rent out GPU capacity for AI, may not survive independently by 2030, while CoreWeave’s bond yields have approached 15%. Even Nvidia’s CEO has acknowledged that capital is scarce.

Oil. Rising tensions with Iran have pushed Brent crude well above $100 per barrel, adding to inflation pressure and raising the odds of higher rates.

Why High-Risk Stocks Fall Harder

Three reasons explain why these forces hit speculative stocks much harder than the broader market.

First, their profits lie further in the future. A stock is worth the cash it will generate, discounted back to today, and higher rates shrink distant cash flows the most. At a 4% rate, $100 earned in 10 years is worth about $68 today. At 6%, it is worth only about $56, a drop of 17%. Cash arriving next year barely changes. Companies earning large profits now hold up better than those whose value depends on profits years away.

Second, many still need outside capital. A company that is losing money or expanding aggressively has to borrow or issue shares. Higher rates make borrowing more expensive, and new shares dilute existing holders.

Third, they simply move more. Since the October 6 high, the S&P 500 has fallen about 1%. The Invesco S&P 500 High Beta ETF (NYSE:SPHB), which holds the index’s most market-sensitive stocks, has fallen about 8%, while the Invesco S&P 500 Low Volatility ETF (NYSE:SPLV) has risen about 5%. The same pattern played out in 2022, when the Fed lifted rates from near zero to above 4%. The S&P 500 lost about 18% that year including dividends, while the ARK Innovation ETF lost 67%.

As Morgan Housel put it, volatility is “a fee, not a fine.” It is the price of admission for higher long-term returns. The real question is whether each business is still worth paying that fee for.

So without further adieu, let’s get down to the results of the analysis.

The following seven investments below are grouped into three tiers, from lowest to highest risk.

Tier One: The Biggest and Most Profitable Companies

1. Berkshire Hathaway

Berkshire Hathaway (NYSE:BRKb) is trading around $540, just below its October 26 record close. The stock is up about 7% this year and 7% in the past month alone, including a 10-day winning streak. It moved sideways for a long stretch before this rally, and buying through that period has paid off.

Three factors are driving the move. Investors are seeking safety: between October 5 and 20, the iShares Semiconductor ETF (NASDAQ:SOXX) fell about 15% while Berkshire kept climbing. Two key holdings, Chevron and Occidental, are each up more than 10% in the past month on higher oil prices. And the businesses are delivering. Operating earnings rose 16% in the second quarter to about $13 billion, with energy up 27% and manufacturing, services and retail up 24%. Berkshire also has about $177.5 billion in insurance float to invest.

Greg Abel is putting cash to work, too. Berkshire bought back $4.5 billion of its own stock in the second quarter, invested $10 billion in Alphabet and acquired Taylor Morrison for about $6.8 billion.

After the rally, though, the stock is no longer cheap. Average analyst targets sit around $542 to $556, UBS sees $628, and Morningstar puts fair value at just $510. Even Berkshire is not crash-proof: Buffett himself has documented four drawdowns of 37% to 59% in the company’s history.

Call: Hold. With shares at their highs, this is a time to let the position grow rather than add to it.

2. Alphabet

Alphabet (NASDAQ:GOOGL) is trading around $290 after falling about 10% following its October 28 earnings report. It is down 7% this year, 14% in the past month and 27% below its $399 record from May.

The business itself is doing very well. Revenue rose 25% to $127.6 billion, and Google Cloud more than doubled, up 103% to $30.7 billion, with a $561 billion backlog. Search still grew 12%, Gemini has passed 1 billion users and operating margins held at 32%.

The problem is spending. Alphabet spent about $51 billion on AI infrastructure in three months and plans to spend $195 billion to $205 billion this year, with more in 2027. That pushed quarterly free cash flow to negative $9 billion. The company also raised $12.4 billion through stock sales, borrowed $28.7 billion and halted buybacks, while revenue and earnings missed expectations. Before the report, analyst targets clustered around $420 to $430, about 45% above the current price, and Morningstar’s fair value stood at $433, though all of these predate the latest results.

Cloud revenue doubled, but capital spending grew even faster, and investors want to know when that spending pays off. On valuation, Alphabet looks like the best business on this list, roughly 27% below its high.

Call: Add. A position was doubled at $280 at the open the day after the drop, with further buying planned in tranches.

Tier Two: Profitable Businesses With More Volatility

3. SoFi Technologies (SOFI)

SoFi Technologies (NASDAQ:SOFI) is trading around $17, down 35% this year and 47% below its November high, although it jumped 13% after its October 27 report.

The business has never been stronger. Revenue rose 44% to a record $1.37 billion, the company added 1.2 million members to reach 17.1 million, and deposits reached $51.3 billion. Profit came in at $241 million, up 73% year over year, and personal-loan charge-offs improved. SoFi raised its full-year revenue guidance to $5.04 billion and set a 2027 target of $6.4 billion.

The stock has struggled because of share dilution, short-seller concerns and higher rates. Wall Street is divided, with an average target of $20 to $21, about 20% upside, while some analysts see $26 to $27.

Call: Hold. The business is progressing as expected. If profitability keeps improving at this growth pace, adding more could make sense.

4. Roundhill Memory ETF (DRAM)

The Roundhill Memory ETF (NYSE:DRAM) is trading around $54. It is up about 95% since its April launch but down 9% in the past month and 33% below its June high. About 75% of the fund sits in three memory chipmakers: Micron, Samsung and SK Hynix.

These are thriving businesses. Micron reported quarterly revenue of $54.2 billion with an 87% gross margin. SK Hynix posted record profits and said its memory capacity is essentially sold out through 2029, and Samsung reported record quarterly operating profit of about $80 billion.

The concern is the pace of price increases. DRAM prices rose about 80% in the second quarter and 40% in the third, but are expected to rise only 10% to 15% in the fourth. Despite record demand, investors fear the memory cycle may be peaking, and volatility has been extreme, with sharp swings in Korean chip stocks this month. Analysts still see about 45% to 65% upside for Micron.

Call: Hold, and buy on large pullbacks. As the most aggressive AI holding here, it should remain a relatively small part of a portfolio.

Tier Three: Highest Risk, Potentially Highest Reward

5. Applied Digital (APLD)

Applied Digital (NASDAQ:APLD) is down 17% this year and almost 59% below its all-time high. The company builds and leases AI data centers, and its business is growing fast. Quarterly revenue roughly quadrupled year over year to $341.9 million. It has 1.41 GW of leased capacity, equal to about $36 billion in contracted revenue. Roughly 250 MW are already live, with more than 600 MW due to come online over the next year.

The selloff comes down to debt. Applied Digital carries about $6.4 billion of debt against $3.7 billion in cash, including restricted cash, and needs billions more to finish construction. Its exposure to CoreWeave and rising borrowing costs add to the concern, and some recent revenue came from construction rather than recurring leases.

Wall Street remains optimistic, with average targets between $56 and $64, nearly triple the current price. Insider buying is a notable signal: the CEO and president recently bought about $6.7 million of stock with their own money at $18 to $19 per share.

Call: Hold, and add on irrational drops. The position stays small, given the risk, but is being built out gradually.

6. IREN

IREN (NASDAQ:IREN) is down about 24% this year, roughly 31% in the past month and about 62% below its record high from last November.

The company started as a Bitcoin miner and is shifting entirely to AI, and its contracts are real. It signed a five-year, $9.7 billion deal with Microsoft and delivered the first of four phases in August. A five-year, $3.4 billion deal with Nvidia gives Nvidia the right to buy 30 million IREN shares at $70. In July, IREN signed another $2.8 billion in contracts with partners including Microsoft, Nvidia and Perplexity. Last quarter, for the first time, AI cloud revenue exceeded Bitcoin mining revenue.

Two things drove the plunge. On October 7, research firm SemiAnalysis rated IREN’s older Canadian sites among the worst in the industry, while its Texas sites looked much better, and the stock fell about 13% over two days. Then the whole AI cloud group sold off on rate and debt fears, with drops of 12% and 11% on October 14 and 16. Bitcoin was not the cause, falling only about 5% over the month.

Of roughly 20 analysts, most rate the stock a Buy, with an average target near $77, more than 2.5 times the current price. Most of those targets were set before this month’s decline, however, so they deserve caution.

Call: Hold, without adding heavily. Extreme dips could still justify small purchases, as they did after the late-August report and during the September and early-October declines.

7. IonQ

IONQ (NYSE:IONQ) is trading around $32.40, down about 28% this year, about 27% in the past month and roughly 60% below its October 2025 record close.

Operationally, the company has delivered. Revenue rose 287% last quarter to $80.1 million. IonQ has raised its full-year revenue guidance three times, from $225 million to $245 million in February to $450 million to $460 million now, including the SkyWater chip manufacturing business it acquired. Its backlog stands at $485 million, and it aims to deliver its first 256-qubit systems in 2027.

The problem is external capital. On October 12, IonQ agreed to buy Zero Trust security company Elisity for up to $1.3 billion, paid entirely in stock, and shares fell about 9%. Two days later, it priced a $2 billion offering of new shares and prepaid warrants at $40, with two extra warrants per unit to buy shares at $69.46, adding 100 million new warrants. The stock fell another 9.5%, then about 9% more when the deal closed on October 16. It was IonQ’s second $2 billion raise within a year; last year’s buyers paid $93 a share. The company is also still losing money, about $120 million last quarter even on an adjusted EBITDA basis.

Most analysts remain optimistic, with average targets of $63 to $68, roughly double the current price.

Call: Cut. That does not mean selling. It means holding the existing position but putting no new money in until the dilution stops and the business shows better developments. The long-term case remains intact, but quantum computing may be further away than originally expected.

Three Rules for Buying Volatile Stocks

A lower price is not the same as a bargain. The business matters more than the share price. SoFi and Micron keep posting record quarters, and Applied Digital’s revenue has roughly quadrupled, yet all three trade well below their highs. IonQ’s business has grown too, but each shareholder’s stake has shrunk.

Buy in tranches, not all at once. No one catches the exact bottom. The memory ETF fell to about $45 in late July, climbed to around $64 by late September, dropped back to roughly $46, then rebounded more than 15% in a few days. Buying in stages spreads the timing risk.

Size positions by risk. The riskier the stock, the smaller the position. Every speculative name here should be a small part of a portfolio built on a core of ETFs and index funds. That is how a 30% monthly drop in a stock like IREN can hurt without derailing the whole portfolio.

Conclusion

The market’s calm surface hides a sharp split between profitable, established companies and the high-growth names that depend on future profits or fresh capital. Among these seven, Alphabet stands out as the clearest opportunity to add. Berkshire is worth holding after its run, while SoFi and the memory ETF are backed by businesses posting record numbers. Applied Digital and IREN suit only small positions, and IonQ is a hold with no new money until the dilution ends.
