ALXN (ALXN) has 2 splits in our ALXN split history database. The first split for ALXN took place on August 25, 2008. This was a 2 for 1 split, meaning for each share of ALXN owned pre-split, the shareholder now owned 2 shares. For example, a 1000 share position pre-split, became a 2000 share position following the split. ALXN's second split took place on May 23, 2011. This was a 2 for 1 split, meaning for each share of ALXN owned pre-split, the shareholder now owned 2 shares. For example, a 2000 share position pre-split, became a 4000 share position following the split.
When a company such as ALXN 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 ALXN split history from start to finish, an original position size of 1000 shares would have turned into 4000 today. Below, we examine the compound annual growth rate — CAGR for short — of an investment into ALXN shares, starting with a $10,000 purchase of ALXN, presented on a split-history-adjusted basis factoring in the complete ALXN split history.
