Director Manko purchases 201,197 shares across 2 trades (May 14-15) for $173,907.79; holdings rise to 2.31M shares (+9.5%)

Manko Joseph M. Jr., a Director at MYOMO, executed 2 separate open-market purchases totaling 201,197 shares for $173,907.79 on May 14-15, 2026, at a blended average price of $0.86. His shareholdings increased from 2.11M shares to 2.31M shares, representing a 9.5% addition to his pre-transaction position. The purchases occurred near the current market price of $0.84, within a 52-week range of $0.60–$3.68, with the stock currently trading 77.2% below its 52-week high. Notably, across his entire open-market history spanning multiple tickers, Manko's 5 prior buy transactions averaged a 90-day return of +22.4% with a 100% win rate, though this cross-ticker track record provides limited insight into MYOMO-specific outcomes. The company remains unprofitable (net income $-3.0M over its latest full fiscal year) despite strong revenue growth of +25.7%, presenting a high-risk/high-growth profile where an established insider's accumulation warrants investor attention to the underlying fundamentals driving his conviction.

Significance 4/10

Director Manko Joseph M. Jr. purchases 75,000 shares (75.0K) for $146,750.00 at One Stop Systems amid -50.4% decline from 52-week high.

Director Manko Joseph M. Jr. executed 2 separate purchases totaling 75,000 shares for $146,750.00 ($146.8K) at a blended average price of $1.96 on August 13–14, 2024. His holdings increased 6.8% to 1,174,899 shares (1.17M shares). The company is unprofitable (net income $-2.3M in the latest quarter, annual revenue decline of -15.9%) and trading at $2.00 is -50.4% from its 52-week high of $4.03. Across his cross-ticker track record, Manko's prior 3 open-market buys averaged -13.2% 90-day returns with a 0.00% win rate, and his single prior sell was well-timed (the stock subsequently declined), suggesting his historical buy decisions have not yielded positive forward returns. The combination of deteriorating fundamentals, steep recent price decline, and a track record of unfavorable buy timing warrants scrutiny of this purchase's motivation.
