Warren Buffett's Berkshire Hathaway (BRK.B, $302.82) took advantage of the market's second-quarter swoon to add to its stakes in Apple (AAPL, $173.16), Chevron (CVX, $156.80), Occidental Petroleum (OXY, $64.34) and a handful of other stocks, but the holding company didn't make any exciting or surprising new moves, a regulatory filing made late Monday revealed. Chairman and CEO Buffett, along with co-portfolio managers Ted Weschler and Todd Combs, were once again net purchasers of equities during the three months ended June 30, although their pace of buying slowed considerably compared with Q1.
