ADMS split history picture
Adamas Pharmaceuticals (ADMS) has 2 splits in our ADMS split history database. The first split for ADMS took place on February 16, 1999. This was a 3 for 2 split, meaning for each 2 shares of ADMS 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. ADMS's second split took place on January 18, 2000. This was a 3 for 2 split, meaning for each 2 shares of ADMS 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.

When a company such as Adamas Pharmaceuticals 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.

Looking at the ADMS split history from start to finish, an original position size of 1000 shares would have turned into 2250 today.
