Technology led a mixed U.S. close
U.S. stocks ended Wednesday, August 12, 2026 with the technology-heavy benchmark ahead of the broader market. The S&P 500 closed at 7,748.50, up 20.30 points, or 0.26%. The Nasdaq-100 gained 217.10 points, or 0.74%, to 29,742.60, while the Dow Jones Industrial Average slipped 22 points, or 0.04%, to 53,770. The gap between the Nasdaq-100 and the nearly flat Dow shows that the session was not a uniform rise across the headline indexes.
| Market | Close | Daily move |
|---|---|---|
| S&P 500 | 7,748.50 | +0.26% |
| Nasdaq-100 | 29,742.60 | +0.74% |
| Dow Jones Industrial Average | 53,770 | -0.04% |
| Cboe VIX | 14.55 | -4.78% |
Volatility and Treasury yields eased again
The Cboe VIX closed at 14.55, down 0.73 point, or 4.78%, from 15.28 on August 11. The U.S. Treasury’s daily par-yield curve put the 2-year yield at 4.20% and the 10-year yield at 4.68%; each was two basis points below the prior market day. A lower VIX and lower benchmark yields accompanied the Nasdaq-100 advance, but one session does not establish a durable volatility, rate or equity trend.
Wheel lens
A VIX close of 14.55 summarizes expected S&P 500 volatility over roughly 30 days. It is not an executable option quote for NBIS or CRWV. An educational wheel review still needs the exact expiry and strike, bid and ask, open interest, event calendar, full cash or share obligation, and assignment tolerance.
Nebius and CoreWeave posted outsized watchlist gains
Within YieldCove’s current watchlist, Nebius Group (NBIS) closed at $259.20, up $65.97, or 34.14%, from $193.23. CoreWeave (CRWV) finished at $107.73, up $17.41, or 19.28%, from $90.32. Cboe’s delayed closing quotes and Nasdaq’s stock screener matched on both regular-session closes and dollar moves. Those feeds establish the magnitude of the moves; closing data alone does not prove a company-specific cause.
| Ticker | Close | Daily move |
|---|---|---|
| NBIS | $259.20 | +$65.97 / +34.14% |
| CRWV | $107.73 | +$17.41 / +19.28% |
Moves of this size can quickly change option moneyness. A sharp rally may move a covered-call strike closer to the stock price or farther in the money, while a cash-secured put can acquire more price cushion without automatically becoming attractive. The stock close does not reveal the next session’s option spread, implied volatility, skew or executable premium. Option premiums are quoted per share, one standard contract normally represents 100 shares, and the complete collateral or delivery obligation matters more than the percentage move alone.
For readers monitoring assignment risk, each dated close is a reference point rather than an order instruction. Rebuilding a delayed quote in a broker after the market reopens means checking the specific contract, its liquidity and the event calendar. Those current contract details can materially change the interpretation even when the verified August 12 stock close remains unchanged.
What the close establishes
The Nasdaq-100 outperformance, lower VIX, lower Treasury yields and large NBIS and CRWV gains are verified August 12 closing facts. They do not identify a favourable strike, premium or trade. This market wrap is educational information only, not personalized financial advice or an order instruction.
