Winmill & Co. Inc filed 74 open market purchase transactions across two tickers, SELF and BXSY, with total buy value of $3,676,224.87. The firm recorded zero sales, zero acquisitions, and zero option exercises in the period covered by the filings. Every transaction used code P, an open market purchase, the only code that shows discretionary conviction. The recent pattern is concentrated in August 2026. Winmill bought SELF on nearly every trading day from August 11 through August 26, with individual purchases ranging from $29,276.99 to $45,045.94. The firm also bought BXSY repeatedly over the same stretch, with larger individual tickets: $94,016 on August 17, $94,016 again on August 14, and $94,552.50 on August 13. The BXSY purchases on August ​​5, ​​6, ​​7, ​​10, and ​​11 ranged from $40,517.40 to $89,900. The last reported trade in the data is an August 26 purchase of SELF worth $43,757.29. The buying bias is unambiguous. Winmill has put cash into both positions on a near daily cadence, with BXSY receiving the larger individual outlays and SELF receiving more frequent smaller purchases. The total sell value is zero, so the firm has not reduced either stake during the reporting window. The filings show a consistent accumulation pattern across two companies, with no offsetting dispositions or compensatory grants clouding the picture.
