Tenaris SA (TS) has 1 split in our TS split history database. The split for TS took place on April 27, 2006. This was a 5 for 1 split, meaning for each share of TS owned pre-split, the shareholder now owned 5 shares. For example, a 1000 share position pre-split, became a 5000 share position following the split.
When a company such as Tenaris SA 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 TS split history from start to finish, an original position size of 1000 shares would have turned into 5000 today. Below, we examine the compound annual growth rate — CAGR for short — of an investment into Tenaris SA shares, starting with a $10,000 purchase of TS, presented on a split-history-adjusted basis factoring in the complete TS split history.
