open-market purchase financial

"reported open-market purchases of Alpha Cognition Inc. common stock"

An open-market purchase is when an investor or a company buys shares on a public stock exchange at the going market price, rather than through a private deal. It matters to investors because these purchases change how many shares are available, can push the stock price up or signal confidence from large buyers, and often affect per-share metrics like earnings—think of it like someone buying lots of apples off a grocery shelf, reducing supply and potentially raising the price.

beneficially own financial

"may be deemed to beneficially own the securities owned directly by the Fund"

Beneficially own means having the economic rights and risks of a security—such as the right to receive dividends, sell the shares, or profit from price changes—whether or not your name appears on the official share register. Think of it like renting a car: you use it and reap the benefits even if the title lists someone else. Investors care because beneficial ownership determines who truly controls value, must be disclosed under securities rules, and can signal potential influence or trading activity that affects a stock’s price.

separately managed account financial

"Securities owned by a separately managed account (the "Managed Account")"

A separately managed account (SMA) is a personalized investment portfolio owned by a single investor and run by a professional manager who buys and sells securities on that investor’s behalf. It matters to investors because an SMA offers tailored asset selection, tax handling, and transparency—like hiring a personal chef who prepares meals to your dietary needs rather than sharing a set menu—so you can align holdings with your goals and see exactly what you own.

pecuniary interest financial
