What is the options industry changing about option symbols in February, 2010?
The change is generally known as the Options Symbology Initiative (or "OSI") and there is a highly comprehensive guide to what occurred here. The basic gist of what occurred was a shift FROM: A coded system in which a shorter (3   to 5 letter symbol) could be used, but   the symbols required a data source to   determine what they meant. MSQ AD   used to be a MSFT Jan 20 option, but   you had to look up MSQ in a table to   know that. TO: A system in which much longer symbols   are needed, but they contain all the   information required to identify a   unique option: DELL 4.000 C 5/16/2010   isn't easy to type, but once you know   how to read it, it's easy to see that   it's an option on DELL, expiring on May 16th 2010, is a call (rather   than a put,) and has a strike price   of 4. As to why they did it, there are a number of benefits, but most important reason is this one:  they were running out of symbols.  The number of permutations of 3-5 letter symbols had been exceeded by the number of options that had been listed, resulting in the need to "recycle" symbols.   This meant that a current option symbol would be the same as an old one, in some cases on a different stock, which was wreaking havoc on historical data.
