5 Best Stocks to Buy in October: AVGO, MELI, UNH, UBER and LITE

October arrives with a mood shift, and the presenter's claim is blunt: September pressure is spent and the strongest quarter of the year is beginning. After months in which investors sold on every Fed scare, a concrete five-stock buying list for October is now on the table. The mix covers AI chips, Latin American e-commerce, a health care giant, a mobility platform and a high-risk optical component maker. The real question is whether these five names are genuine October opportunities or simply a well-told story.

September's scorecard looks mixed at first glance, and the discrepancy deserves a clear explanation. In the presentation, the S&P 500 is described as finishing September roughly flat or slightly higher. Yet the September split confirmed by Tapeboard data tells a different story, since Tapeboard shows the S&P 500 closing September down about 0.78 percent. The same dataset puts the Nasdaq up 1.74 percent, the Dow down 4.96 percent and the Russell 2000 down 5.90 percent. The mismatch largely reflects closing timing differences, as late-month moves pulled the indexes in opposite directions. September therefore goes down as a soft month for the broad market but a resilient one for the technology-heavy side.

Why October Looks Different

October has a far better record than its scary reputation suggests, which is the basis for calling it a bear killer. Since 1945 the S&P 500 has averaged a 0.6 percent September decline, while October has delivered average gains near 0.9 percent. Research compiled by Kiplinger has long stressed that October tends to mark the starting gun for a fourth-quarter rally. The midterm-year pattern is even stronger, with October ranking historically as the single best month of such years. Seasonality alone is no reason to buy, yet after a weak September the statistical wind is blowing in October's favor.

The number one reason markets enter October in better spirits is the softer signal from the Fed. A month ago markets priced roughly a 65 percent chance of an October rate hike, and that probability has now fallen toward 20 percent. In other words, futures markets now imply about an 80 percent chance the Fed stands pat in October. According to CNBC, the latest jobs and inflation readings explain in hard numbers why hike expectations have faded. The presenter frames this as validation of a call made months ago and reminds investors not to panic-sell on every data release.

What the Data Says About the Fed

The economic data tour explains step by step why Fed pressure has eased, with each release reinforcing the last. Job openings came in near 7 million against 7.2 million expected, a sign that labor demand is cooling. On inflation, figures published by the BEA put headline PCE near 3.4 percent and the core measure around 3.0 percent. The ISM services index printed 54.5, signaling expansion, while its prices sub-index jumped 6.8 points to 77.9. Weekly jobless claims stayed low at 197 thousand, September added a modest 29 thousand jobs with unemployment at 4.2 percent, and prior months were revised down by 60 thousand. The most striking piece is the 10-year yield at 5.3 percent, roughly a 24-year high, which means both pressure and opportunity for yield hunters.

The Five-Stock October List

First on the list is Broadcom, one of the strongest names in AI infrastructure. The company posted third-quarter revenue of 29.6 billion dollars, up 86 percent, and generated 13.7 billion dollars of free cash flow. Management's 34.8 billion dollar sales outlook signals that AI chip demand is not slowing. The company announcement carried by PRNewswire confirms the record quarter and the elevated forecast. The stock carries an Edge score of 79, with analysts averaging near 510 dollars, implying about 40 percent upside. The presenter's personal target is 500 dollars, on the view that Broadcom stays a portfolio anchor while AI spending continues.

The second name is Latin American e-commerce leader MercadoLibre, and the story is durable growth. The company grew second-quarter revenue 50 percent to 10.2 billion dollars, its thirtieth straight quarter above 30 percent growth. Buyer count rose 26 percent while the Pago unit lifted monthly active users 30 percent and assets under management 68 percent to 23 billion dollars. Coverage published through the Mercado Libre news site shows payment volume above 100 billion dollars and ad revenue up 73 percent. The stock started the year down 15 percent yet holds the list's top Edge score of 82, with 2027 earnings near 55.79 dollars a share implying a 30.4 forward multiple and a 0.6 PEG. The presenter calls that mix a rare blend of growth at a fair price.

Third is health insurance giant UnitedHealth, a pure recovery play. The company reported a quarter with 112 billion dollars of revenue, 8 billion dollars of operating profit and adjusted earnings of 6.38 dollars a share, with a full-year guide near 19.75 dollars. Third-quarter results due on October 13 make the stock a natural October candidate. Analysis from Motley Fool likewise stresses that the medical cost ratio and the balance sheet sit at the center of the recovery case. The shares swung between 250 and 460 dollars over the past year and are up about 3 percent over three months, with an Edge score of 73. A forward multiple near 17.5 times sits below the peer average, and with the price back above its 200-day line a target near 475 dollars points to about 25 percent upside.

Fourth is Uber, down 16 percent on the year, where the thesis is that the fall went too far. With an Edge score of 73, the autonomous driving partnerships form the core of the story, with more than 35 thousand robotaxis planned alongside Lucid and Nuro. The schedule shared through Uber investor channels puts the San Francisco Bay Area first, with the Houston rollout targeting 2027. A 100 thousand vehicle and 28 city vision for 2028 backed by Rivian and Nvidia extends the company's autonomous ambitions. Threats such as Meta's driver-assisted Muse effort look contained, since safety and regulatory hurdles should slow any rapid rollout. Cash-flow-based valuation near 82 dollars implies 21 percent upside and the analyst average near 105 dollars points to 50 percent, while the presenter expects around 80 dollars into year end.

Fifth and riskiest is optical component maker Lumentum, a play on fiber demand inside AI data centers. The company reported quarterly sales of 1 billion dollars and guided to a strong 1.22 to 1.275 billion range, with a 40 percent operating margin. Shipments of the 1.6 terabit optical module mark the start of a fresh product cycle. Sector coverage summarized by 247WallSt notes Citi's 11 billion dollar 2030 call on the optical switching market and a 560 percent twelve-month run to an all-time high. With an Edge score of 70, the forward multiple of 58 looks steep, yet a PEG below 1 suggests growth still carries the price. Hence the advice to keep the position small while staying exposed to the AI infrastructure wave.

Valuation, Risks and the Watch Plan

Taken together, the five names offer different kinds of valuation logic rather than one uniform bargain. Broadcom and Lumentum trade on rich multiples but fund them with double-digit growth and strong cash flow. MercadoLibre keeps a fair multiple despite 50 percent growth, while UnitedHealth and Uber trade below their history. The common thread is a preference for solid balance sheets, positive cash flow and concrete growth drivers when expectations run high. That discipline works as a vital filter against expensive but unsupported stories while rates stay elevated.

The risks deserve equal weight, since every thesis faces a concrete threat. For Broadcom the danger is a slowdown in AI capital spending plus customer concentration, where deferred orders could compress the multiple fast. MercadoLibre faces currency swings and competition across Latin America, while regulation and medical cost surprises loom over UnitedHealth. For Uber, autonomous delays or price wars are the main hazards, and for Lumentum unmet sky-high expectations could trigger sharp corrections. On the macro side, a further rise in the 10-year yield would pressure valuations across all growth names. So the list should be treated as a living portfolio to prune on news flow, not a one-time basket.

Four catalysts will decide the list's fate in the coming weeks. First stop is the October 13 UnitedHealth report, where the medical cost ratio and any 2026 outlook could confirm or kill the recovery thesis. Second, fresh Broadcom AI order announcements and supply chain signals deserve close attention. Third comes operational detail on the Houston launch and the pace of fleet growth. Finally, inflation and jobs data will shape the rate path into the Fed's October meeting, where soft prints help stocks and hot prints hurt.

To wrap up, October statistically stands with buyers despite its fearsome reputation. Easing Fed pressure, supportive seasonality and the start of earnings season form the three legs of the bullish case. Broadcom plays AI, MercadoLibre e-commerce, UnitedHealth recovery, Uber post-drop value and Lumentum high-risk high-reward. The framework is not gospel, but it beats walking into October without a plan, and the final call always belongs to each investor's risk profile, horizon and position sizing.
