Aflac stock closed at USD 117.55 on the NYSE on September 16, 2026, adding roughly 0.4% compared with the prior session. The move came as the S&P 500 declined about 0.4% to 7,551.81, leaving the insurer modestly ahead of the wider market on the day.
September 16, 2026 in numbers
Aflac Inc. (ISIN US0010551028, NYSE: AFL) saw its shares trade in a corridor around the USD 116 to USD 118 area on September 16, 2026, before settling at USD 117.55 at the close in USD terms on the NYSE. Per NYSE and portal data, that closing level represented a gain of approximately 0.4% on the day, consistent with intraday readings that showed the stock quoted near USD 117.25 earlier in the session. Daily turnover ran in line with recent averages as market participants digested several pieces of ownership and valuation news.
One prominent storyline was fresh attention to Aflac’s valuation after its shares closed at USD 117.55, with commentators noting that this recent close sits very close to some fair value estimates around USD 117.71 and USD 118.00, suggesting the stock is trading near what many models deem intrinsic value, according to analysis highlighted by Simply Wall St and further DCF work discussed by GuruFocus. Against that backdrop, the modest advance to USD 117.55 left the shares just below some published intrinsic value estimates near USD 120.27, while still comfortably within their 52-week trading range.
Ownership dynamics also drew focus in the last session. A Form 4 filing summarized by StockTitan detailed that a major holder conducted open-market sales totaling 13,600 Aflac common shares on September 14, 2026, at weighted average prices between roughly USD 116.00 and USD 117.07, corresponding to an aggregate market value of about USD 1.56 million. In parallel, coverage of stake adjustments by Japan Post Holdings reported that the institution sold around USD 1.58 million of Aflac stock while the shares traded near USD 117.25, as noted by Investing.com. Despite these sales from a large shareholder, options and equity commentary indicated that the stock edged higher, with one options report stating that Aflac shares were up about 0.4% around USD 117.99 intraday even as the stake was trimmed, according to Schaeffers Research. Taken together, the combination of insider and institutional selling, coupled with commentary on fair valuation, framed the modest advance in Aflac’s stock price on September 16, 2026, as the shares outperformed a declining S&P 500.
Today’s drivers and upcoming dates
Today, September 17, 2026, the focus around Aflac is likely to remain on ownership changes and valuation narratives rather than a specific scheduled company event, as the recent filings and stake trimming stories continue to circulate through markets. The insider Form 144 described by StockTitan outlines a planned sale of 13,201 Aflac shares with an aggregate market value around USD 1.56 million based on September 16, 2026 pricing, adding another data point for investors monitoring insider activity. More broadly, the overall US market tone, including moves in major indexes like the S&P 500 following its September 16, 2026 decline to 7,551.81 as reported by The Seattle Times, provides the macro backdrop for Aflac’s next moves once trading resumes today.
