> what Warren Buffett's strategy is, and it said buying undervalued companies and holding for a long time
No. It’s cheap leverage applied to low-volatility assets bought for a fair price [1]. (Munger got him off the ‘cigarette butt’ strategy of buying on the cheap.)
According to the paper you posted (interesting analysis), it’s not just low-vol assets, but good quality ones. Also, they would no doubt do a lot more buying of undervalued (good quality) companies if they weren’t by this point “too big to care”, so to speak.
Please don’t do this.
