PTIX split history picture
Protagenic Therapeutics (PTIX) has 3 splits in our PTIX split history database. The first split for PTIX took place on September 16, 1997. This was a 3 for 2 split, meaning for each 2 shares of PTIX owned pre-split, the shareholder now owned 3 shares. For example, a 1000 share position pre-split, became a 1500 share position following the split. PTIX's second split took place on September 02, 1999. This was a 3 for 2 split, meaning for each 2 shares of PTIX owned pre-split, the shareholder now owned 3 shares. For example, a 1500 share position pre-split, became a 2250 share position following the split. PTIX's third split took place on March 23, 2023. This was a 1 for 4 reverse split, meaning for each 4 shares of PTIX owned pre-split, the shareholder now owned 1 share. For example, a 2250 share position pre-split, became a 562.5 share position following the split.

When a company such as Protagenic Therapeutics splits its shares, the market capitalization before and after the split takes place remains stable, meaning the shareholder now owns more shares but each are valued at a lower price per share. Often, however, a lower priced stock on a per-share basis can attract a wider range of buyers. If that increased demand causes the share price to appreciate, then the total market capitalization rises post-split. This does not always happen, however, often depending on the underlying fundamentals of the business. When a company such as Protagenic Therapeutics conducts a reverse share split, it is usually because shares have fallen to a lower per-share pricepoint than the company would like. This can be important because, for example, certain types of mutual funds might have a limit governing which stocks they may buy, based upon per-share price. The $5 and $10 pricepoints tend to be important in this regard. Stock exchanges also tend to look at per-share price, setting a lower limit for listing eligibility. So when a company does a reverse split, it is looking mathematically at the market capitalization before and after the reverse split takes place, and concluding that if the market capitilization remains stable, the reduced share count should result in a higher price per share.

Looking at the PTIX split history from start to finish, an original position size of 1000 shares would have turned into 562.5 today.
