my two cents...
BRK is currently valued at 1.6x BV
MKL is currently valued at 1.7x BV
FFH is currently valued at 1.1x BV (and even less if you add the unbooked adjustments to FMV of TC/Quess and FIH).
WB has always said that at 1.2x his company is undervalued and at 2x it is overvalued. I imply that the mid point 1.6x is his idea of FMV.
In my view FFH is so thinly covered by analysts and trades such low volumes its entirely possible (probable) that it is mispriced.
As they digest AWH, getting the under writing under control (AWH and BRIT), leverage the float AND grow revenues into a better market the insurance businesses look well placed to do really well over the next few years. Looking at some of the larger investments, BB, TC/Quess, FIH and Gravalia there is the possibility of some serious upside. Having dropped the hedging and winding down the CPI options we'll get a chance to see FFH for what it can really do. The market could wake up at any time and award this the multiple it deserves.
For me, the most compelling source of information is the conference calls and listening directly to PW. He has changed his emphasis notably this year:
1. Dropping the bond holdings, removing equity hedges, going on the offensive.
2. Still maintaining a conservative posture eg not reaching for yield.
3. Added AWH to the stable and stated that this is the last big acquisition.
4. Repeatedly stated that they will firstly strengthen FFH financial position and then buy back stock. (first part is underway and stock purchases starting slowly).
5. Most importantly on the year-end call he said "$15bil revenue now in place, we expect to generate 15% return to shareholders of about net $70/share"....later in the Q&A he said..."we expect $2bil after tax in 2018". I have never heard him get this close to giving guidance even though he emphatically said he was not and never would issue guidance.
All thats needed now is a liitle proof, if the next few quarters go according to plan I fully expect to see FFH priced at +1.5x BV by the end of the year.
