CEO Michael K Korenko bought 200,000 shares of RDGL at $0.06; 4 of 5 prior same-ticker buys yielded positive 90d returns; current price -60.0% from 52-week high.

Michael K Korenko, CEO and President, purchased 200,000 shares at $0.06, increasing his holdings to 11.29M shares. His prior trade history at RDGL shows a strong timing pattern: 4 of 5 prior buys at this ticker were well-timed at the 90-day mark, with positive 90d returns ranging from +5.3% to +39.2%. However, the current backdrop is challenging—the stock trades at $0.06, down 60.0% from its 52-week high and off 9.5% in the past 30 days. Vivos Inc remains unprofitable with quarterly revenue of $36.1K and full-year net income of -$1.2M, though annual revenue growth reached +144.2%. The CEO's demonstrated accuracy on same-ticker timing merit attention, but investors should assess whether the company's path to profitability supports a reversal from current price weakness.

Significance 4/10

CEO Korenko buys 200,000 shares of RDGL at $0.06; stock down -56.2% from 52-week high, CEO's prior RDGL trades mixed (1 of 5 well-timed).

Michael K Korenko, CEO and President, purchased 200,000 shares at $0.06 on 2025-12-31, raising his holdings to 10.94M shares. The transaction occurs as the stock trades at $0.07, approximately -56.2% from its 52-week high of $0.16 and down -22.1% over the past 90 days. Examining his prior trades at RDGL specifically, his timing record is inconsistent: of 5 prior purchases at this ticker, only 1 was well-timed at the 90-day mark, with outcomes ranging from +21.4% to -35.7%. His broader cross-ticker track record shows a 50.00% 90-day win rate across 12 prior buys, suggesting only moderate historical accuracy in purchase timing. Given the company's negative net income of $-507.3K in its most recent quarter and unprofitable full-year status, this open-market purchase by the CEO occurs in a fundamentally challenged context, yet the stock's -56.2% decline from its 52-week peak may indicate substantial repricing or distressed conditions worth monitoring.

Significance 3/10

CEO Michael K Korenko buys 100,000 shares of RDGL at $0.07; stock down 56.2% from 52-week high, company unprofitable.

Korenko purchased 100,000 shares at $0.07 on 2025-12-02, adding to a 10.74M share position. The purchase follows another buy at the same company just 12 days prior (2025-11-20) and comes as RDGL trades 56.2% below its 52-week high with a 30-day decline of 14.8% and 90-day decline of 24.5%. At the same-ticker level, Korenko's prior five trades at RDGL show mixed outcomes: two generated 90-day gains (+17.4%, +21.1%) while two generated 90-day losses (-8.2%, -27.5%), with only 1 of 4 prior buys well-timed at the 90-day mark. The company reported a negative net income of $-507,294.00 in its latest quarter and was unprofitable over its most recent full fiscal year, despite 23.2% annual revenue growth. The modest transaction value of $7,220.00 and the pattern of recent consecutive buys near depressed prices warrant monitoring of whether sustained buying reflects conviction or reverses given the company's ongoing losses.

CEO Korenko bought 100,000 RDGL shares at $0.06; stock down 62.5% from 52-week high, company unprofitable

CEO Michael K Korenko purchased 100,000 shares at $0.06 on 2025-11-20, increasing his holdings to 10,635,090 shares. The stock has declined 62.5% from its 52-week high and 24.5% over 30 days, while the company reported negative net income of $-507,294.00 in the latest quarter and operated unprofitably over its full fiscal year. His prior four trades at RDGL show mixed results—only 1 of 5 prior buys achieved positive 90-day returns, with a timing pattern of 20.0% success rate. His cross-ticker track record shows 10 prior buys with an average 90-day return of +7.6%, a materially stronger record than his RDGL-specific history, suggesting this ticker presents elevated execution risk relative to his broader pattern.

CEO Korenko buys 100.0K shares at $0.08; stock down 43.7% in 30 days, 55.6% from 52-week high

Michael K Korenko, CEO and President, purchased 100,000 shares at $0.08 on 2025-08-14, expanding his holdings to 10.54M shares. The timing is notable: the stock trades at -55.6% from its 52-week high of $0.18 and has declined 43.7% over the trailing 30 days, establishing a meaningful low-point entry. Korenko's prior transaction history at this ticker (5 prior buys) shows mixed results: only 1 of 5 trades achieved positive 90-day returns, and his most recent two purchases (2024-10-28 and 2024-09-30) both suffered 30-day declines of -35.7% and -20.2% respectively. Against this backdrop, the company reported only $15.0K in latest quarterly revenue, a net loss of $645.5K for the full year, and trades at a $36.3M market cap—positioning this as a highly speculative holding where insider accumulation coincides with elevated downside risk and limited visibility into near-term profitability.

Significance 5/10

CEO Michael K Korenko bought 50,000 shares of RDGL at $0.14 on 2024-10-28, holding 10.44M post-transaction.

Korenko, who already holds 10.44M shares (10.44M shares post-transaction), purchased an additional 50,000 shares at $0.14, continuing a pattern of open-market buys at RDGL spanning July through October 2024. His prior five trades at this ticker show mixed timing: his July 29 buy yielded +60.4% over 90 days, but more recent August and September purchases have not yet reached measurable 90-day outcomes. The stock is currently trading at $0.14 (the transaction price) but remains -44.0% from its 52-week high and -11.1% over 30 days, despite a +49.2% gain over 90 days. Fundamentals present a challenge: the company reported negative annual revenue growth (-46.6%), a net loss of $-503.5K in the latest quarter, and is unprofitable on a full-year basis with a market cap of $58.5M. The timing pattern across RDGL trades is limited (1 well-timed outcome out of 5 trades measured where 90-day data exists), and his cross-ticker track record shows stronger performance (+16.3% avg 90d return, 75% win rate) than his same-ticker history suggests he might expect.

CEO Michael K Korenko buys 50,000 shares (50.0K) of VIVOS at $0.16 on 2024-09-30

Michael K Korenko, CEO and President, purchased 50,000 shares at $0.16, representing a 0.5% increase to his 10.39M share position. His prior RDGL trades show mixed outcomes: his 5 previous purchases at this ticker in 2024 have produced 30-day returns ranging from +4.6% to +54.2%, but only the June 4 buy has a measurable 90-day result, which was -20.3%. His cross-ticker track record shows a 66.67% 90-day win rate across 7 prior buys with an average 90-day return of +1.6%, but 0 of his 1 prior measurable same-ticker buy has achieved a positive 90-day outcome. The current price of $0.16 is -36.0% from the 52-week high and the company reported annual revenue decline of -46.6% with an unprofitable full fiscal year (net income of $-503.5K). Near-term price momentum is positive (+19.0% over 30 days), but the company's fundamental deterioration and this insider's inconsistent timing record at this specific ticker merit scrutiny.

CEO Korenko buys 50,000 shares of RDGL at $0.11; stock down 56% from 52-week high, 4th buy in 2 weeks amid 46.6% revenue decline

Korenko Michael K, the CEO, purchased 50,000 shares at $0.11 on 2024-08-13, his fourth buy in the past two weeks at RDGL. This follows rapid acquisitions on 2024-08-07, 2024-08-01, and 2024-07-29, totaling approximately 80,000 shares in 15 days. The stock trades at -56.0% from its 52-week high and -40.5% over the last 30 days, creating a steep entry point. Fundamentally, the company faces headwinds: annual revenue contracted 46.6% year-over-year, the latest quarter generated only $13.5K in revenue, and net income sits at -$503.5K. While the CEO's cross-ticker track record shows a 100% 90-day win rate across 6 prior buys (avg 90d return +12.6%), this does not yet establish a pattern at RDGL specifically—prior same-ticker buys remain unmeasurable or show mixed near-term results (+5.4% 30d in June, +4.1% 30d and +9.5% 90d in November 2023). The rapid sequence of small purchases during a prolonged price decline merits observation, but without clear operational recovery signals or a demonstrable same-ticker track record, the trade reflects accumulation at depressed prices rather than a high-conviction buying opportunity.

CEO buys 50,000 shares at $0.12 amid -56.0% decline from 52-week high; stock down -39.7% in 30 days

CEO Michael K Korenko purchased 50,000 shares at $0.12 on 2024-08-07, increasing his holdings to 10.29M shares. The transaction occurs against a severe backdrop: the stock is trading at $0.11, down -56.0% from its 52-week high of $0.25 and down -39.7% over the past 30 days. Fundamentally, the company reported revenue of $4.5K in its latest quarter with net income of -$558.5K, and experienced annual revenue decline of -46.6%; the company remains unprofitable. At RDGL specifically, Korenko's prior two trades with measurable 90-day outcomes (2023-11-13 and 2023-10-18) both generated positive returns of +9.5% and +15.7%, respectively. This current purchase is his fifth buy at this ticker in less than two months, following acquisitions on 2024-08-01, 2024-07-29, and 2024-06-04, establishing a pattern of accumulation during a period of material stock deterioration and operational distress.

CEO Michael K Korenko buys 50,000 RDGL shares at $0.09 on 2024-08-01; stock down 49.9% in 90 days amid revenue decline of -46.6%.

CEO Michael K Korenko purchased 50,000 shares at $0.09 on 2024-08-01, bringing his holdings to 10,235,090 shares, a 0.5% net addition. This buy occurs in a deteriorating context: the stock has fallen 49.9% over the trailing 90 days and 60.0% from its 52-week high, while fundamental metrics show severe strain—the company reported annual revenue declined 46.6% year-over-year, net income stood at negative $558,539.00 in the latest quarter, and it has been unprofitable over its most recent full fiscal year. Korenko's prior trades at RDGL show a mixed pattern: his two measurable same-ticker buys yielded positive 90-day returns (9.5% and 15.7%), demonstrating some timing accuracy at this specific stock, though the company's current operational trajectory presents material headwinds. The buy itself is small in relative terms ($4,360.00 total value) and occurs just two days after another purchase at the same ticker, suggesting continued accumulation rather than isolated conviction.
