UPRO's $151.3 Million Sale Was Math, Not a Call on Nvidia
A triple-leveraged S&P 500 fund sold $151.3 million of stock on Sept. 24, including $12.5 million of Nvidia, and bought nothing. Here is why the tape reads that way.
ProShares UltraPro S&P 500 (UPRO) sold $151.3 million of stocks on Sept. 24, including $12.5 million of Nvidia, bought nothing and trimmed 485 positions — a pattern consistent with mechanical rebalancing in a 3x leveraged index fund rather than a discretionary view on any holding.
A filing-driven headline can look like a verdict when it is really arithmetic. ProShares UltraPro S&P 500, which trades under the ticker UPRO, sold $151.3 million of stocks on Sept. 24, bought nothing at all, and reduced 485 separate positions. Among the disposals was $12.5 million more of Nvidia (NVDA), the single most talked-about holding in any S&P 500-linked portfolio.
Read in isolation, that looks like a fund manager stepping away from the AI trade. Read in context, it looks like what a triple-leveraged index product does every day it is asked to shrink.
What UPRO actually is
UPRO is a leveraged exchange-traded fund designed to deliver three times the daily return of the S&P 500. It is not a stock picker. There is no analyst inside deciding that Nvidia has run too far or that Microsoft looks expensive. The fund's job is to hold enough exposure — through index equities, futures and swaps — that its net asset value moves roughly three times as much as the benchmark each session, then reset that exposure at the close.
Two forces drive the size of the underlying basket. The first is the daily reset: when the index rises, a 3x fund must add exposure; when it falls, it must cut. The second is creations and redemptions. If holders pull money out, the fund sells assets to meet redemptions across the whole book, not in one or two names.
That second force is the one that fits the Sept. 24 pattern. Selling across 485 positions while buying nothing is the signature of an across-the-board reduction, not a stock-specific decision. A discretionary manager who had soured on Nvidia would sell Nvidia and redeploy the cash. This book sold everything and redeployed nothing.
The Nvidia line, in proportion
The $12.5 million of Nvidia stands out because of the name attached to it. As a share of the day's activity it works out to roughly 8% of the $151.3 million total — an illustrative calculation from the two reported figures, not a disclosed weighting. That is broadly the order of magnitude you would expect from a mega-cap sitting near the top of a capitalization-weighted index, sold down alongside hundreds of smaller lines.
The other names flagged alongside it in the GuruFocus report — AAPL, MSFT, AMZN, GOOGL and IQMM — reinforce the point. Those are the index's heaviest constituents. Any proportional reduction in an S&P 500 basket touches them first and hardest, purely because of their weight.
Monday's tape shows the leverage working
Live prices as of 15:20 GMT on Monday, Sept. 28, make the mechanism visible. The S&P 500, via SPY, was at $765.08, down 0.81% from a prior close of $771.35, with a day range of $763.72 to $768.61. UPRO was quoted at 148.53, down 2.41% from 152.20, with a range of 147.69 to 150.55. That is almost exactly three times the index move — roughly a 3.0x ratio, by simple division of the two percentages — which is the product doing precisely what its prospectus promises.
The irony is that Nvidia was one of the day's stronger large caps. NVDA traded at 230.15, up 2.26% from 225.07, inside a range of 226.50 to 233.21. Meanwhile the rest of the mega-cap complex sagged: Microsoft at 509.96 (-1.20%), Amazon at 247.05 (-1.05%), Alphabet at 340.64 (-0.95%) and Apple close to flat at 340.75 (-0.09%). The Nasdaq 100, via QQQ, was down 1.37% at $734.30; the Dow, via DIA, slipped 0.67% to $514.01.
So on the session in question, a fund that had lightened its Nvidia line would have been on the wrong side of that specific name while the index it tracks fell anyway. That contradiction is exactly why position-level disclosures from index products should not be read as opinions.
Who should care, and who should not
For anyone tracking institutional sentiment on Nvidia, this disclosure carries close to no information. Flows from leveraged index vehicles are a function of index level and investor demand for leverage, not conviction on semiconductors. If you are building a picture of whether large holders are trimming AI exposure, discretionary managers' filings are the relevant evidence; a 3x S&P 500 fund is noise in that signal.
For holders of UPRO itself, the relevant facts are different and more consequential:
- Daily compounding. Three times the daily return is not three times the return over a month or a year. In a choppy, directionless market, the daily reset erodes value even if the index ends flat.
- Asymmetry on the downside. A 0.81% index decline became a 2.41% decline in UPRO on Monday. The same mechanics apply in reverse, but losses compound from a smaller base each time.
- It is a trading tool. Products structured this way are built for short holding periods. Using them as a long-term substitute for index exposure is a different risk than most buy-and-hold investors think they are taking.
What to watch from here
The useful thing to monitor is not which names the fund sold but whether the selling continues and what it implies about demand for leverage. Sustained one-way reductions with no offsetting purchases point to redemptions — investors stepping back from geared long bets on U.S. equities. Renewed one-way buying points the other way.
That flow read matters more broadly than the fund itself. Leveraged index products are a visible, high-frequency measure of appetite for risk at the retail and fast-money end of the market. When the index is falling — as it was on Monday across all three major benchmarks — and geared long vehicles are shrinking rather than being bought on the dip, it suggests positioning is being reduced rather than pressed.
None of that requires a single view on Nvidia, Apple or Microsoft. The fund did not express one. It rebalanced, and 485 lines moved because the index says they should.

Frequently asked questions
Does UPRO's Nvidia sale mean the fund is bearish on Nvidia?
No. UPRO is a leveraged index fund built to track three times the daily return of the S&P 500. It holds names in proportion to the index and has no discretionary stock-picking process. Selling $12.5 million of Nvidia while reducing 485 other positions and buying nothing is consistent with an across-the-board reduction, not a view on the chipmaker.
Why would a fund sell $151.3 million and buy nothing?
Two reasons dominate for a leveraged index product. If investors redeem shares, the fund sells assets proportionally across its whole book to raise cash. And if the index falls, a 3x fund must cut exposure to keep its leverage ratio on target. Either can produce one-way selling with no offsetting purchases.
How does 3x daily leverage actually work?
The fund resets its exposure each day so that tomorrow's move is roughly three times the index's move. That reset is daily, not cumulative. On Sept. 28, SPY was down 0.81% and UPRO was down 2.41% — close to three times. Over longer periods, compounding means returns can diverge substantially from three times the index.
Which stocks were named alongside the disclosure?
The report listed UPRO itself plus NVDA, AAPL, MSFT, AMZN, GOOGL and IQMM. The mega-cap names are the heaviest weights in the S&P 500, so any proportional reduction in an index basket touches them in the largest dollar amounts simply because of their index weighting.
What were the major indexes doing on Sept. 28, 2026?
As of 15:20 GMT, all three main U.S. benchmarks were lower. SPY was at $765.08, down 0.81% from a $771.35 prior close. QQQ, tracking the Nasdaq 100, fell 1.37% to $734.30. DIA, tracking the Dow 30, slipped 0.67% to $514.01. Nvidia bucked the trend, up 2.26% at 230.15.
Is a 3x leveraged ETF suitable for long-term holding?
Products structured for three times daily returns are designed as short-term trading tools. Because leverage resets each session, volatility erodes value over time even when the underlying index finishes flat. Investors seeking long-run index exposure typically use unleveraged funds; geared vehicles carry a materially different risk profile.
