I assume you are not an experienced investor (and presumably not a holder). Everyone investing and commenting here knows it is a speculative counter. The worst result here is for a 100% loss =- 26.5 p but the upside is of a possible huge rise. We are gambling on that outcome.
Look at the Buford Short Position icon at the top of the page. Philadelphia shows a change of NIL on 17 October. Therefore as the total short for them is shown as o.52% by definition it must have existed prior to 17 October. I do not understand why a nil entry would be shown but there you go.

Hi Levis. Interesting post. Recurring patterns fascinating. I understood the share is splitting sometime. Bought Put for same reason and split just happening after just a few weeks. Good luck with the trading. Dividends on a non closure - music to my ears.
