AET (AET) has 4 splits in our AET split history database. The first split for AET took place on June 04, 1979. This was a 3 for 2
split, meaning for each 2
shares of AET 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. AET's second split took place on December 14, 2000. This was a 2 for 1 split, meaning for each share of AET owned pre-split, the shareholder now owned 2 shares. For example, a 1500 share position pre-split, became a 3000 share position following the split. AET's third split took place on March 14, 2005. This was a 2 for 1 split, meaning for each share of AET owned pre-split, the shareholder now owned 2 shares. For example, a 3000 share position pre-split, became a 6000 share position following the split. AET's 4th split took place on February 21, 2006. This was a 2 for 1 split, meaning for each share of AET owned pre-split, the shareholder now owned 2 shares. For example, a 6000 share position pre-split, became a 12000 share position following the split.
When a company such as AET 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 AET split history from start to finish, an original position size of 1000 shares would have turned into 12000 today. Below, we examine the compound annual growth rate — CAGR for short — of an investment into AET shares, starting with a $10,000 purchase of AET, presented on a split-history-adjusted basis factoring in the complete AET split history.
