Change in SPDR ETF

A change in SPDR ETF outflow is noticed this morning. It has been continuously selling for a long time and this morning it is noticed that it bought 2.71 tonnes, according  to a compilation of data provided on their website. Yesterday morning they were holding 1051.47 tonnes and now it is 1054.18 tonnes. The volume is not much but if it is a change in sentiment that could mean a lot.  I haven't found it covered in any news yet, may be it is not a big deal or it could just be a technical glitch. But I think it is noteworthy, so posted it here.
