CapitolRadar analysis
7 trades, with buying concentrated in early 2021
AEIS has 7 tracked trades from 2021-02-09 through 2026-09-29: 5 buys and 2 sells involving 3 distinct traders. The largest quarterly cluster was 2021 Q1, when 3 trades were recorded and all 3 were buys. Activity then fell to one trade in each reported active quarter: a sell in 2021 Q2, a buy in 2024 Q2, a sell in 2025 Q2 and a buy in 2026 Q3.
The balance is therefore tilted toward purchases, with buys representing 5 of the 7 tracked transactions. However, the sample is small and spread across more than five years, so the buy-sell count should not be treated as a broad or continuous pattern. No additional active quarters are identified in the supplied data.
3 buyers account for all 5 purchases
Susie Lee recorded 3 AEIS buys, the most among the tracked buyers, with her latest dated 2021-02-23. Gilbert Cisneros recorded 1 buy, dated 2026-09-29, while Josh Gottheimer recorded 1 buy, dated 2024-06-27. The provided facts do not identify the traders responsible for the 2 sells, so no seller-level comparison can be made.
Overlap elsewhere in the buyers’ disclosed activity was limited but visible: 2 of the AEIS buyers also bought AMD, CRWD, MSFT and SAIL. One also bought AMAT, and one also bought COMP. These overlaps describe co-occurring disclosed purchases only; they do not establish a common rationale or relationship among the companies.
Disclosure timing and value limits
Congressional transaction disclosures may be filed up to 45 days after a trade, meaning the latest activity can be incomplete or appear with a lag. Transaction amounts, when disclosed as ranges, support only estimated values rather than exact dollar totals; no amount ranges were provided here, so capital deployed cannot be quantified. With only 7 trades and 3 traders, conclusions from frequency, direction or cross-stock overlap remain sample-sensitive.
