Hi thanks for your question. My name is Tony, I can assist with this.
Normally, the phrase is defined in a will to make clear what it means, but if not, then it's going to follow the definition in s.55 of the Administration of Estates Act 1925 (referring to personal chattels). You can get the link to that here: http://www.legislation.gov.uk/ukpga/Geo5/15-16/23/section/55
It includes all such things a lawn mowers and cars etc.
It would not normally include shares.
