Berkshire Hathaway (BRK.B) disclosed last quarter that it bought a sizable stake in Taiwan Semiconductor (TSM) stock. How sizeable? How about just over 60 million shares at just under $69 per share. This equates to roughly a $4.1 billion dollar outlay for Berkshire and famed chairman and CEO Warren Buffett.
The news of the acquisition on November 15 sent TSM stock soaring over 10% on the day. Shares moved from under $73 pre-announcement to close above $80 post-announcement. Taiwan Semiconductor has since pulled back somewhat to the $78 area.
