That's why Warren Buffett famously hates stock splits. Buffett has never approved a split of Berkshire Hathaway 's ( BRK.A -0.28% ) Class A shares, which cost about $270,000 per share, because he believes splitting the stock to "affordable" prices attracts undesirable short-term traders. Nonetheless, Berkshire still issued cheaper class B ( BRK.B 0.83% ) shares in 1996, then split those shares 50-for-1 in 2010 to fund its acquisition of railroad Burlington Northern Santa Fe.
