September 18, 2026 in numbers
Broadcom Inc. (ISIN US11135F1012, Nasdaq: AVGO) finished the last completed session on September 18, 2026 at USD 357.67, compared with a prior close of USD 347.30, marking a gain of 3.0% on the day per Nasdaq data. Intraday, the shares traded within a range that kept the closing price between the day’s high and low, and turnover accelerated, with volume around 44 million shares well above the recent average, indicating active trading into the expiration of index and options contracts. In the same session, the Nasdaq Composite index also advanced, while the semiconductor segment outperformed, underscoring the sector tailwind behind Broadcom’s move.
As USTV reported on September 21, 2026, Broadcom shares rose 2.97% on September 18, 2026 in a session marked by the so-called quad-witching, when stock index futures, stock index options, single-stock options and single-stock futures all expired. The report highlighted that the Philadelphia Semiconductor Index gained nearly 3% that day, reflecting broad strength across chipmakers and providing a supportive backdrop for Broadcom’s advance. A separate sector overview from 21st Century Business Herald likewise noted that most large US semiconductor and technology stocks rose on September 18, 2026, with chip names leading the gains.
Today’s focus for Broadcom
Looking ahead to today’s US session on September 21, 2026, Broadcom is trading after a week in which its shares have recovered part of a multi-month decline from record levels, leaving the stock still below its 52-week high but back above recent lows, according to market comparisons from MSN. Broader US market drivers today include the fallout from Friday’s derivatives expiration and ongoing positioning in technology and semiconductor names, which may continue to influence demand for Broadcom shares. Investors also track upcoming economic data releases and interest-rate expectations given the sensitivity of high-growth technology and chip stocks to financing conditions and overall risk appetite.
