Robinhood, AppLovin vault higher as the "inclusion effect" is in full force

Membership has its privileges.

Robinhood Markets and AppLovin jumped early Monday after both were tapped for inclusion in the blue chip S&P 500 after the close of trading on Friday. Emcor, which was also added to the index saw a more modest gain.

(Robinhood Markets, Inc. is the parent company of Sherwood Media, an independently operated media company subject to certain legal and regulatory restrictions.)

As Sherwood’s own Hyunsoo Rim, recently pointed out there’s been something of a resurgence in the so called “index inclusion effect” — the tendency for stocks added to the index to enjoy a brief burst of outperformance after their addition to the blue chip index is announced.

Rim writes:

According to a 2023 Harvard study, the average announcement-day return for S&P 500 additions dropped from 9.4% in the 1990s to just 0.8% by the late 2010s — partially because markets got better at absorbing these shocks, and traders got better at predicting inclusions.
Now, though, a new Goldman Sachs analysis suggests the inclusion effect may be staging a comeback.
Since 2021, stocks newly added to the S&P 500 have outperformed the equal-weighted index by an average of 4 percentage points on the announcement day — with nearly three-quarters of those stocks beating the benchmark.

On the one hand, it’s understandable why a sudden announcement of inclusion — as came after the close Friday — would send shares higher.

The committee at S&P Dow Jones Indices keeps such information tightly controlled until it is made public. When the news comes it means that a lot of money has to suddenly flow into these shares. Some $13 trillion in “indexed” assets are directly tied to directly mirroring the composition of the S&P 500. And an additional $7 trillion or so in assets like mutual funds are benchmarked — or measured against — the index.

In practice, many of these “benchmarked” funds come close to mirroring the index while making small modifications that they hope can generate some outperformance. (This is know as “closet indexing.”)

On the other hand, it’s unclear why the potency of the inclusion effect should ebb and flow over time.

Goldman Sachs analysts, who wrote on the index inclusion effect recently, noted that its recent re-emergence may have something to do with the surge of stocks popular with retail investors that have been added to the S&P 500 lately. They wrote:

Many of the best-performing recent index additions have been retail favorites. Retail trading activity has taken on greater importance in equity markets post-COVID, especially at the stock-level. Based on data from GS Global Banking and Markets, Coinbase, Super Micro Computer, and Palantire were extremely popular among retail traders and sharply outperformed on announcement day.

That seems consistent with the market reaction today.

Both AppLovin and Robinhood are big retail favorites and saw big jumps. While the other addition, a slightly less sexy electrical and mechanical contractor and facilities management company called Emcor, is actually down on the day.

Retail darling Planet Labs soars on earnings pop for second straight quarter

Planet Labs, which operates a network of satellites that record data, images, and information about the Earth, surged more than 40% after reporting better-than-expected quarterly numbers before the open of trading Monday.

It was the second straight quarter when the money-losing company’s quarterly update generated a massive market reaction. The stock jumped nearly 50% after numbers came out in June.

The company, which went public via SPAC in 2021, raised its full-year revenue guidance and notched its second straight quarter of positive free cash flow. Analysts and investors watch free cash flow closely as it can signal when a company’s business is starting to become more durable.

While the company is small — roughly $2.5 billion in market cap — it has posted pretty serious gains, rising almost 300% the past 12 months. Planet Labs also appears to have a fairly large retail shareholder base.

Just 57% of its float is in the the hands of institutional investors, according to FactSet data. That’s roughly the same as other retail favorites such as Palantir, though Planet Labs is no where near as highly valued as the defense data and AI software company led by CEO Alex Karp.

OpenAI’s cash burn suggests selling Nvidia because of reported Broadcom chip orders may not make much sense

When Broadcom announced that it booked $10 billion in new orders from a customer reported to be OpenAI, shares of their major AI chip rivals tanked.

The judgement of the Invisible Hand was that this was nearly a zero-sum outcome: $130 billion of market cap erased from Nvidia and Advanced Micro Devices, and a $135 billion increase in Broadcom’s market value.

But looking at this from the perspective of near-term cash flows, the market’s view seems off.

The Information is reporting that OpenAI now expects to burn through $115 billion by the end of 2029 (or more than 11 seasons’ worth of NFL broadcasting rights).

Let’s zoom in on this tidbit from The Information:

But the biggest change emerging from OpenAI’s latest projections was to its cash flows. The company projected it will burn more than $8 billion this year, or roughly $1.5 billion higher than its prior projection from earlier this year. Cash burn will more than double to more than $17 billion next year—$10 billion higher than what the company earlier projected

That $10 billion fits all too neatly with the $10 billion in orders from a major new customer that Broadcom CEO Hock Tan pointed to in the chip designer’s earnings call.

(Cheers to @lokoyacap for flagging this on X)

Assuming the reporting around OpenAI and Broadcom is accurate, these orders for ASICs don’t look to be displacing what the ChatGPT creator was going to spend on Nvidia’s GPUs, but are just in addition to it! The money’s not coming out of Jensen Huang’s pockets, it’s coming out of OpenAI’s coffers. Their spending budget is just getting bigger.

Perhaps if you squint, there’s a world in which OpenAI may prefer to have an additional $10 billion in Nvidia GPUs rather than ASICs, and I am still of the belief that hyperscalers diversifying their chip sources due to constrained top-end supplies isn’t a good sign for the company selling the most in-demand product.

But it’s quite intriguing, and says something about the depth of the pockets that fuel the AI boom, that OpenAI’s reported new relationship with Broadcom has seemingly no direct negative financial impact on Nvidia in the near term.

Broadcom’s post-earnings romp continues on heavy volumes

As Broadcom enjoys a rush of new orders from a major new customer (reported to be OpenAI), it’s also reveling in a flood of traffic into the stock.

Volumes are running at 2.5 times their daily average through 1:20 p.m. ET as traders continue to bid up shares in response to the brighter outlook for 2026 revenues, which sent the stock up 9.4% on Friday.

The chip designer is basking in a flood of price target hikes from Wall Street, with Bank of America, JPMorgan, Argus Research, Citigroup, Bernstein, Deutsche Bank, Morgan Stanley, Barclays, Piper Sandler, Rosenblatt Securities, Wells Fargo, and Susquehanna upping their view on how high shares can go since the company reported earnings last week.

Separately, Taiwanese industry outlet DigiTimes is reporting that orders from several other leading tech companies for custom-made Broadcom chips (or ASICs) are “already in the pipeline.” This report has not been corroborated by our own or any other publication’s reporting to date.

SpaceX spectrum deal sends would-be rivals lower

Shares of struggling satellite services company EchoStar soared Monday, after the company — which had recently tottered close to bankruptcy — announced the sale of some of its wireless spectrum licenses to Tesla CEO Elon Musk’s SpaceX for $17 million.

The sale provides a competitive advantage to Musk’s growing Starlink satellite services business, as the licenses it is acquiring from Echostar allows Starlink to operate ground based broadband and cellphone services, the Wall Street Journal reported.

Entities that stood to be hurt by the emergence of a Musk-led SpaceX Starlink service got hit hard on the news. AST SpaceMobile, which has plans to offer a similar satellite-to-consumer cellular service, tumbled.

So did wireless tower providers like Crown Castle and American Tower. Low cost cellular service provider T-Mobile, which had a deal with SpaceX, also slumped, as Luke noted earlier, along with other large wireless telecommunication services providers.

The wireless telecommunications industry grouping within the S&P 500 was down more than 2.5% shortly after noon, making it the worst performing industry within the S&P 500 on Monday.
