CapitolRadar analysis
31 trades skewed toward 24 sells
31 tracked WAB trades were disclosed by five distinct traders from November 22, 2019 through August 25, 2026. The activity comprised 24 sells and seven buys, so sells represented roughly 77% of the trade count. This is a small sample spanning nearly seven years, and trade counts alone do not show the dollar balance between purchases and sales.
Among the quarters provided, 2022 Q4 had the highest count, with seven trades and no buys. Other sell-only periods included 2023 Q1 with three trades, 2023 Q4 and 2024 Q1 with one each, 2025 Q3 with two, and 2026 Q3 with three. Together, the listed quarterly figures cover 21 of the 31 tracked trades, so they do not provide a complete quarter-by-quarter distribution for the full period.
5 buys appeared in 2025 and 2026
2025 Q1 recorded two trades, both buys, while 2026 Q2 recorded two trades, including one buy. In contrast, all three trades listed for 2026 Q3 were sells. These recent quarterly counts remain too small to establish a durable change in trading behavior.
3 disclosed buyers account for all 7 purchases
Ro Khanna reported three buys, most recently on May 1, 2026. Markwayne Mullin reported two buys, most recently on February 3, 2025, and Susie Lee reported two buys, most recently on November 26, 2019. Among these buyers, one also bought each of SYK, UAL, WDAY, ADI, ARES and BSX; the supplied data does not identify which buyer matched each ticker.
Congressional disclosures can appear up to 45 days after a transaction, so reported activity may not be timely. Transaction amounts are disclosed in ranges, making any value-based totals estimates; no such totals are provided here. The limited number of traders and buys also warrants caution when interpreting the pattern.
