Phelan William P: insider trades

Director at Soluna Holdings, Inc. 2 open-market purchases and 8 sales not made under a pre-set plan, reported from November 2, 2016 to September 4, 2026.

Would copying Phelan William P’s purchases have beaten the S&P 500?

Too few purchases to judge. None of their purchases has 12 months of prices after the report; we judge insiders once they have 20. The figures below can swing a long way on a handful of trades. None of their purchases could be priced, so there is no copy portfolio. None of these trades can be measured yet: either the window after the report has not finished or the share price was under $5 when it was reported.

With 296 insiders tested, some will look skilled or unskilled by chance alone: when we replaced each insider’s stocks with random companies bought on the same days, about 5.7 cleared the bar ahead and 23.3 behind. One record on its own proves little.

“Average vs S&P 500” is the stock’s return including dividends minus the index’s over the same dates, from the close on the first trading day after the report, or from the close on the trade date. Only windows that have finished are counted. For sales, a negative figure means the stock lagged after it was sold, so selling was the right call (green). “Went the right way” is the share of purchases that beat the index, or of sales that trailed it. The t-statistic uses one average per year of reports, because one person’s trades bunch into the same stock and weeks, and needs trades in at least four different years; the p-value comes from the t distribution with that number of years (with four years, a t of 2 has p = 0.14). “Some evidence” means p under 5%, “strong evidence” p under 1% over at least six years.
