13F - reading the AUM

Am I right in thinking that if I add up together all the disclosed positions a fund has I still won't arrive at AUM?

What if they're levered 10x - then their actual AUM is 10x smaller?
Also as far as I understand shorts / cash are not disclosed?

Is this right?

The 13-F is only showing U.S. stock positions, so very rarely is that going to be the same as AUM regardless of leverage. For example, looking at Baupost's 13-F doesn't tell you much about their positions because they have ~$30B AUM but under $6B in U.S. stocks.

This is one of the reasons you have to be a bit careful looking at 13-Fs, they're useful but don't give you the whole picture. You also don't know how the positions on the 13-F interact with positions that aren't disclosed. Positions on the 13-F may be acting as hedges for other positions or may in fact themselves be hedged by other positions.

 

gotcha - this is great, thanks.

What would be the most reliable way of estimating AUM for a fund if bloomberg / reuters / FT don't really mention it? Neither does their website obv.

The way Ah see it, is that it took a revolution f a bihllion people for your darn short to work out!
